Make sure that work is only carried out by qualified personnel under due observance of the five safety rules,
the warning information in this operating instructions and the safety information on the product itself.
Handling of Power Cells
DANGER
Risk of electrical Shock
Do not touch metal frame of cell. Capacitors store hazardous energy. Disconnect all sources of supply. Wait
until all LEDs on cell control board are out before serving cell.

6 A5E02417952B AF, 05/2012
Discharging the DC link voltage
DANGER
DC link capacitor discharge time
After the mains power has been switched off, there are still high voltages present on the DC link capacitors.
These cause death or serious injury if the safety instructions are not observed or if the equipment is handled
incorrectly.
The DC link capacitors require up to 10 minutes before they are discharged to a safe value (< 60 V).
Once you have switched off the main power supply, do not touch the device or carry out any maintenance work
or repair work until the 10 minutes have elapsed.
Measure the voltage once the discharge time has elapsed.
DANGER
Hazard due to auxiliary voltages
Auxiliary voltages are still present even after the make-proof grounding switch has been closed. Contact with
live parts can result in death or serious injury.
When working on the equipment, always wait for the discharge times specified on it and in the product
documentation to elapse and always observe the five safety rules.
Safety precautions when working on the equipment
DANGER
General safety precautions when working on the equipment
Note the following information for your own safety:
● Always disconnect the equipment before working on it.
● Leave the covers in place during normal operation and keep the cabinet doors closed.
● Do not use any instrumentation if you know it is defective or damaged.
● Secure the main circuit breaker in the OFF position so that it cannot be reconnected, for example by
removing the switch unit when working on a connected motor or the feeder cable to the motor.
● Ground the converter cabinet and/or the chassis units properly with the make-proof grounding switch to
ensure that no accessible parts of the equipment are energized or connected in any way to a dangerous
voltage source.
● If the optional make-proof grounding switches are not available, then use an earthing spider for grounding
purposes. Read the information provided in the section "Safety instructions regarding maintenance and
repairs" in "Maintenance and servicing" in your operating instructions.
● Always follow the national regulations and local specifications when working on the equipment.

A5E02417952B AF, 05/2012 7
Closing the make-proof grounding switch
The converter is optionally equipped with make-proof grounding switches (N44 or N45).
The make-proof grounding switches can be closed when the doors have been closed and the following prerequisites are
fulfilled:
● The DC link voltage must be de-energized.
● The EMERGENCY-OFF switch on the cabinet unit must be activated.
● The key-operated switch on the converter must be set to the OFF position.
● A delay time of 10 minutes must have expired.
If the auxiliary voltage fails completely, the make-proof grounding switch cannot be closed.
The doors are secured by the electrical door magnet system and can be opened only after the make-proof grounding switch
is closed.
Procedure
1. Take the socket spanner, which can be found in the tool set, and turn it counter-clockwise.
Figure 1 Make-proof grounding switch closed
2. The contacts are closed and the voltage DC link is grounded.
CAUTION
You must note the following to prevent injury or material damage:
For operation, the make-proof grounding switch must be deactivated and the grounding switch lever must be removed
before the voltage is switched on. The interlock mechanism is thus activated.
This prevents grounding while the system is live, which could cause a DC link short-circuit.

8 A5E02417952B AF, 05/2012
Hot surfaces
WARNING
Protection from burns
Certain components (e.g. the heat sink or filter reactor) can become very hot during operation. These components can
remain hot for a long time after operation.
The anti-condensation heating is activated when the converter is not operating and the limit value set on the temperature
regulator is reached. Once activated, the anti-condensation heating can generate a great deal of heat.
Serious injury (scalding) may occur if you come into contact with hot surfaces.

Figure 2 Particulary hazardous areas
DANGER
Danger due to voltages
During operation and shortly after the system has been switched off with the EMERGENCY OFF button, high
voltages are still present in the converter and its components. These voltages may remain if the connection to
the motor is not removed or grounded. The hazard occurs with the use of PEM machines and synchronous
motors where de-excitation is not immediate. In this case, voltages can remain if the connection to the motor is
not removed or grounded.
Never force the doors open during operation if the make-proof grounding switch is open or while the power DC
link capacitors are discharging.
The discharge time for the DC link capacitors once the EMERGENCY OFF button has been pressed is 10
minutes.

Electromagnetic fields
Safety information
WARNING
Electromagnetic fields electro smog
Electromagnetic fields are generated by the operation of electrical power engineering installations such as transformers,
converters or motors.
Electromagnetic fields can interfere with electronic devices, which could cause them to malfunction. For example, the
operation of heart pacemakers can be impaired, potentially leading to damage to a person's health or even death. It is
therefore forbidden for persons with heart pacemakers to enter these areas.
The plant operator is responsible for taking appropriate measures (labels and hazard warnings) to adequately protect
operating personnel and others against any possible risk.
● Observe the relevant nationally applicable health and safety regulations. In Germany, electromagnetic fields are subject
to regulations BGV B11 and BGR B11 stipulated by the German statutory industrial accident insurance institution.
● Display adequate hazard warning notices.
● Place barriers around hazardous areas.
● Take measures, e.g. using shields, to reduce electromagnetic fields at their source.
● Make sure that personnel are wearing the appropriate protective gear.

A5E02417952B AF, 05/2012 11
Safety Precautions and Warnings
The Siemens Perfect Harmony (PH) series of Medium Voltage (MV) Pulse Width Modulated (PWM) Variable Frequency
Drives (VFD) are designed with considerable thought to personal safety. However, as with any piece of high power
equipment, there are numerous internal connections that present potentially lethal voltages. In addition, some internal
components are thermally hot to the touch. Follow the dangers, warnings and cautions listed in this section when working in
or near the VFD system.
WARNING
Potential Arc Hazard
Arcing can result in damage to property, serious injury and even death.
The equipment has not been tested for resistance to internal arcing.
Avoiding arc hazard risks is dependent upon proper installation and maintenance. Incorrectly applied equipment,
incorrectly selected, connected or unconnected cables, or the presence of foreign materials can cause arcing in the
equipment.
Follow all precautionary rules and guidelines as used in working with Medium Voltage switchgear.
DANGER
Electrical Hazards!
● Always follow the proper lock-out/tag-out procedures before beginning any maintenance or troubleshooting work on the
drive.
● Always follow standard safety precautions and local codes during installation of external wiring. Protective separation
must be kept between extra low voltage (ELV) wiring and any other wiring as specified in IEC 61800-5-1.
● Always work with one hand, wear insulated composite or steel toe safety (electrical hazard rating) shoes, electrical
safety gloves, and safety glasses. Also, always work with another person present.
● Always use extreme caution when handling or measuring components that are inside the enclosure. Be careful to
prevent meter leads from shorting together or from touching other terminals.
● Use only instrumentation (e.g., meters, oscilloscopes, etc.) intended for high voltage measurements (that is, isolation is
provided inside the instrument, not provided by isolating the chassis ground of the instrument).
● Never assume that switching off the input disconnect will remove all voltage from internal components. Voltage is still
present on the terminals of the input disconnect. Also, there may be voltages present that are applied from other
external sources.
● Never touch anything within the GenIV converter cabinets until verifying that it is neither thermally hot nor electrically
alive.
● Never remove safety shields (marked with a HIGH VOLTAGE sign) or attempt to measure points beneath the shields.
● Never run the drive with cabinet doors open. The only exception is the control cabinet which contains extra low voltages
(ELV).
● Never connect any grounded (i.e., non-isolated) meters or oscilloscopes to the GenIV system.
● Never connect or disconnect any meters, wiring, or printed circuit boards while the drive is energized.
● Never defeat the instrument’s grounding.
● Only qualified individuals should install, operate, troubleshoot, and maintain this drive. A qualified individual is one
familiar with the construction and operation of the equipment and the hazards involved.
● Hazardous voltages may still exist within the GenIV converter cabinets even when the disconnect switch is open (off)
and the supply power is shut off.
● When a system is configured with drive bypass switchgear (e.g., contactors between line and motor, and drive and
motor), these switches should be interlocked so that the line voltage is never applied to the drive output if the medium
input voltage is removed from the drive.

12 A5E02417952B AF, 05/2012
WARNING
● Always comply with local codes and requirements if disposal of failed components is necessary (for example, CPU
battery, capacitors, etc.).
● Always ensure the use of an even and flat truck bed to transport the GenIV drive system. Before unloading, be sure
that the concrete pad is level for storage and permanent positioning.
● Always confirm proper tonnage ratings of cranes, cables, and hooks when lifting the drive system. Dropping the
converter cabinet or lowering it too quickly could damage the unit.
● Never disconnect control power while medium voltage is energized. This could cause severe system overheating
and/or damage.
● Never store flammable material in, on, or near the drive enclosure. This includes equipment drawings and manuals.
● Never use fork trucks to lift converter cabinets that are not equipped with lifting tubes. Be sure that the fork truck tines fit
the lifting tubes properly and are the appropriate length.
CAUTION
ESD Sensitive Equipment!
● Always be aware of electrostatic discharge (ESD) when working near or touching components inside the GenIV
converter cabinet. The printed circuit boards contain components that are sensitive to static electricity. Handling and
servicing of components that are sensitive to ESD should be done only by qualified personnel and only after reading
and understanding proper ESD techniques. The following ESD guidelines should be followed. Following these rules can
greatly reduce the possibility of ESD damage to PC board components.
● Always transport static sensitive equipment in antistatic bags.
● Always use a soldering iron that has a grounded tip. Also, use either a metallic vacuum-style plunger or copper braid
when desoldering.
● Make certain that anyone handling the GenIV printed circuit boards is wearing a properly grounded static strap. The
wrist strap should be connected to ground through a 1 megohm resistor. Grounding kits are available commercially
through most electronic wholesalers.
● Static charge buildup can be removed from a conductive object by touching the object to a properly grounded piece of
metal.
● When handling a PC board, always hold the card by its edges.
● Do not slide printed circuit boards across any surface (e.g., a table or work bench). If possible, perform PCB
maintenance at a workstation that has a conductive covering that is grounded through a 1 megohm resistor. If a
conductive tabletop cover is unavailable, a clean steel or aluminum tabletop is an excellent substitute.
● Avoid plastic, StyrofoamTM, vinyl and other non-conductive materials. They are excellent static generators and do not
give up their charge easily.
● When returning components to Siemens LD A, always use static-safe packing. This limits any further component
damage due to ESD.
Additional safety precautions and warnings appear throughout this manual. These important messages should be followed
to reduce the risk of personal injury or equipment damage.

Safety information on transportation
In the following sections, note the following:
● Transportation unit refers to the converter cabinet before it has been unpacked;
● Cabinet refers to the converter cabinet after it has been unpacked.
Safety precautions during transportation
Pay attention to the safety-related instructions on transport, storage and correct handling of the equipment in this chapter
and on the packaging.
● In this way you will prevent personal injury and material damage.
● Particular care must be taken during transportation and handling to ensure that no components are bent and/or no
alterations made to isolating distances.
WARNING
Transportation in accordance with proper procedures
The transport unit/cabinet is heavy. The center of gravity is in the upper half of the cabinet. The equipment can tip over
if it is not transported correctly or if the means of transport used is not permittted.
Death, serious injury, or material damage can result.
Ensure that the transport unit/cabinet is only transported by trained personnel using a permitted means of transport and
permitted lifting equipment. The equipment must always be positioned the right way up and must not be tipped.
Permissible means of transportation
Use a fork-lift truck and/or crane for transporting and aligning the transport units.
Securing the load
Secure the load in the following ways:
● Retaining straps
● Positive locking on the loading surface, e.g. by wedging the transport unit on the truck loading surface
● Fitting of spacers
Make sure that the individual transportation units are properly lifted and transported in the marked upright position.

Placing the device down
WARNING
Avoid vibrations
Serious jolts or knocks during transportation can damage the equipment and destroy the insulation material. This can result
in insufficient insulation with respect to ground or a ground flashover (the relevant error messages are output).
For this reason, avoid impacts and jolts when setting the equipment down.
Center of gravity of the transportation unit/cabinet
The diagram below shows the center of gravity of the transport unit/cabinet, which must always be taken into account when
the cabinet is lifted and installed.
)URQWYLHZ 6LGHYLHZ
Figure 4 Example illustration of the center of gravity of the cabinet
WARNING
Take center of gravity into account
A sticker or stamp showing the precise specifications regarding the center of gravity of the cabinet is attached on each
transportation unit.
Failure to take into account the center of gravity can result in death, severe injury, or material damage.
You must take into account the center of gravity during transportation.
Further information about transporting the units
For detailed information about dimensions and center of gravity specifications, see the dimension drawing in Layout
diagrams and dimension drawings in your operating instructions.
Note
Observe the transport instructions
You must put in place the measures described to avoid damaging the housing during transportation and to operate the
devices under the permissible climatic conditions (compliant with EN 50178). See also the technical specifications in
Technical specifications/test certificates in your operating instructions.

22 A5E02417952B AF, 05/2012
Off-loading
Due to the size and weight of Perfect Harmony components, it is important to carefully plan all handling operations. Off-
loading from the truck is often the most critical operation because of the limited access. Advance planning and coordination
among the manufacturer, the carrier, the installation contractor, and the owner are vital. Prior considerations should be made
for ceiling heights, door widths, and ease of installation.
DANGER
Never use eye bolts for lifting any of the Perfect Harmony cabinets. Eye bolts are used at the beginning of the
manufacturing process when the cabinets weigh much less.
Prior to moving the unit, ensure that:
● The unit doors are closed
● The unit is in an upright position
● The unit is stabilized to prevent tilting
● Each cell’s locking latches are tie-wrapped in an upright position
General Lifting Instructions
WARNING
Liability of Lifting and appropriate Equipment
● Though lifting options are presented, the final lifting is the liability of those lifting the structures. Care and attention
should be used while lifting to monitor the condition of the lift at all times. Low lifting heights and slow movements
should be made where possible.
● The actual lifting process must be monitored continously. Also, the equipment used must be sized appropriately
according to forces to which they will be subjected. This analysis has been prepared without knowing any of the
equipment available on site, so tailored lifting descriptions cannot be made.
To avoid personal injury or equipment damage follow the warnings and cautions in this section.

A5E02417952B AF, 05/2012 27
Placement, Location and Storage
Note
● Intake cooling air enters the drive through front-mounted ventilation grilles, and is exhausted through the fan mounted on
top of the enclosure. Do not place the drive where the intake/exhaust paths could be blocked. A minimum of 36
(915 mm) is required from the front of the drive unit.
● Place the drive in a location where the removable access plates interface with the cable entry to the drive.
After final inspection, move the drive promptly to its final position or dry indoor storage area. When choosing the location for
the Perfect Harmony drive, be sure the area is clean, flat, dry, and the front of the drive is easily accessible even when the
drive doors are open. Allow at least 36´´ (915 mm) of clearance in front of the units to allow the drive doors to fully open.
Shims may be necessary to level the cabinet on uneven floors.
Avoid extreme temperatures, such as below -5° C or above 55° C; avoid conditions as noted on the shipping labels. If it is
necessary to temporarily store the drive in an outdoor area, heaters may be placed in the drive and operated to prevent
moisture accumulation. A protective cover such as plastic or a tarp should be placed over the drive to reduce any problems
due to the outside elements. This is especially important if the storage is for more than a few days.
WARNING
If the mounting surface is not flat, the metal cabinets of the Perfect Harmony drive may buckle, causing the cabinet doors
to be misaligned and/or not open and close properly. Shims may be necessary to level the drive for proper door operation.
WARNING
If a drive is de-energized (or in storage) for 24 months or more, the Harmony cell electrolytic capacitors will need to be
reformed.

28 A5E02417952B AF, 05/2012
Safety information on storing the equipment

● The conditions for storing the converter must be met in order to ensure perfect operation.
● Ensure that it is not stored for longer than the permissible maximum of two years.
Safety information on bolting the transport units together
CAUTION
Mechanical damage
Strain occuring during transport can exert mechanical pressure on the components.
Material damage can result.
● Line the cabinets up precisely with each other in order to avoid shearing forces when the base units are bolted
together.
● Make sure that the ground on which the converter is to be located is completely flat.
Detailed Information on commissioning and maintenance
Note
For more detailed information, please refer to the Commissioning and Maintenance manual.

A5E02417952B AF, 05/2012 29
Notes on electrical installation
External Wiring
Refer to the project drawing C set for the customer I/O connection interface (#12 - #22 AWG). All hardwired I/O cabling
should be routed and terminated prior to commissioning.
CAUTION
Electrical Hazard!
Standard safety precautions and local codes must be followed during installation of external wiring.
Protection separation must be kept between extra low voltage (ELV) wiring and any other wiring as specified in the CE
safety standard IEC 61800-5-1.
The transformer has a set of +5%, nominal, -5% voltage taps for compensating the primary voltage source. The GenIV VFD
(Variable Frequency Drive) is shipped with the nominal taps connected. This means that the VFD secondary cell voltages
are at the nominal 750 VAC (for example) for rated primary input voltage. Customer-supplied medium voltage cables enter
an access plate in the top (input/output section) or bottom (transformer section). See Figures GenIV Enclosure (4 160 V
Output, 200 - 1 100 Hp), GenIV Enclosure (4 160 V Output, 1 000 - 2 500 Hp) and Enclosure (4 160 V Output, 300 -
3 500 Hp) or project drawings for exact locations.
Customer-supplied low-voltage cables (#8 - #22 AWG) for the control enter an access plate in the top (input/output section)
or bottom (transformer section). See Figures GenIV Enclosure (4 160 V Output, 200 - 1 100 Hp), GenIV Enclosure (4 160 V
Output, 1 000 - 2 500 Hp) and Enclosure (4 160 V Output, 300 - 3 500 Hp) or project drawings for exact locations.
DANGER
Ensure that the entire system is earth grounded at its P.E. ground point.
NOTICE
The transformer primary winding neutral point is designed to operate floating (ungrounded). Do not bond the transformer
primary winding neutral point to ground. Failure to adhere to this instruction will cause large, unbalanced currents to
circulate in the ground/neutral path of the drive’s input source system during drive energization.
Note
Torque specifications for the Perfect Harmony drive are listed in Table Torque Specifications for the Perfect Harmony.
Note
Conductor sizes for input medium voltage termination may vary based on the size of the drive and the dynamics of the
system. The customized system schematic (included with your drive) shows the conductor size used on the main
transformer taps. The size of the input conductors will usually match or exceed this size. However, be sure to size the input
conductors appropriately for your particular application, taking into account the length of the input power feed and your local
standards and electrical codes. Labels are applied near the connects recommending the use of 75 °C conductors.

30 A5E02417952B AF, 05/2012
NOTICE
To maintain EMC compliance, input medium voltage wiring must be installed in metallic electrical conduit and routed
through the approved access plates.
Customer supplied low voltage I/O cabling #12 - #22 AWG must be routed separately from power cables / medium voltage
cables. Shielded low voltage cables shall maintain shield integrity for the length of the cable including all inter-connections
and the shield shall be grounded only at the source.
The input and output medium voltage terminals (L1, L2, L3 and T1, T2, T3) are offset from one another and have two NEMA
one-hole pattern configurations (vertical and horizontal) to facilitate top or bottom cable termination. MV terminations are
provided for 3/8 fasteners.
Note
The GenIV design is best accommodated for single-conductor single-core medium voltage cables. Three-conductor single-
core cables are not recommended and may require special attention.
Note
Customer should not terminate MV cables at drive output until start of commissioning cycle.

A5E02417952B AF, 05/2012 31
Safety information regarding connection of the power cables
Before starting work, please note the following points:
WARNING
Maintaining the degree of protection
Any changes to the floor panel or the roof panel in order to modify the cable entry port area can result in the converter no
longer meeting the requirements for the degree of protection shown.
Using a converter with an inadequate degree of protection can result in death, serious injury, or material damage.
To maintain the degree of protection, seal any access holes made in the floor panel/roof panel immediately after installation
so that they are air tight.
CAUTION
Damage from short-circuits
Transposing the input and output terminals can result in a short-circuit, which can destroy the converter.
● Check the electrical connections after service work.
● The operating coils for contactors and relays in the converter must be connected to overvoltage limiters (e.g. RC
elements or varistors).
WARNING
Check the cable insulation
Improperly laid or damaged cables and incorrectly attached cable shieldings can heat up in places and cause fires or short-
circuits wherever they make contact.
● Make sure that the cable shields are intact and insulate any that are damaged.
● Make sure that a short-circuit cannot occur on the power cables due to failure of the insulation as a result of improper
cable installation.
CAUTION
Using non-magnetic parts
The use of magnetic parts, e.g. magnetic cable clamps is not permitted in the converter.
Using magnetic parts can damage the converter.
Only use parts that consist of non-magnetic material.
DANGER
Grounding the equipment
The converter must be grounded to ensure that it operates safely.
Using a converter with insufficient grounding can result in death or serious injury. Serious material damage can also result.
Ensure that the converter is always grounded and that the protection and monitoring systems are functioning.

32 A5E02417952B AF, 05/2012
Notes on components and options
Cabinet Details
Note
The Control Door, Control Section, and I/O Section are accessible without a K2 key. However, the medium voltage
components located in the I/O section are separated by fixed polyglass barriers.
Note
A cell lifter may be required for installing or removing power cells from the GenIV system.
DANGER
Remember that the cell chassis is not grounded and when energized can float to lethal voltages.
WARNING
The power cells include discharge resistors to dissipate stored energy after the input voltage is removed. The power cell
DC bus voltage decays to less than 50 VDC in less than 10 minutes.
Cabinet Details Cooling
An extremely important part of the installation process is making provisions for exhausting the heat that is generated by the
operation of the drive. Although the GenIV drive is highly efficient, there may be as much as a 3.0% energy loss emitted in
the form of heat from inside the system cabinetry. This heat must be transmitted to the outdoor air or into the structure of the
building at a rate fast enough to prevent the ambient temperature from rising above the rated conditions.
Note
Never energize the drive without operational blowers providing air flow. The drive contains components that have losses in
the IDLE state. Without air flow, these losses may heat up components and eventually damage the drive over time.
CAUTION
Stop of the converter
After the STOP command is issued, the converter output is in the INHIBIT state.
In this state it is very important that the cooling system stays running because the heat from the converter components has
to be dissipated. Due to the switching of the auxiliary voltage in this state, the converter components which have long
thermal time constants can get damaged.
If this happens, consistently the transformer and/or power cells will get damaged!
WARNING
High voltages
Disabling the drive does not necessarily remove voltage form the motor terminals! The motor, especially if spinning, may
have residual voltage on the terminals, and anything connected to them. Always observe the five safety rules and adhere
to the safety measures.

A5E02417952B AF, 05/2012 33
Using protection blocks
The Siemens LD A SOP development process for the NXG Control is detailed in controlled document EPI-001.
CAUTION
Using protection blocks
Protection blocks ensure safe drive function.
Failure to follow protections as outlined in these critical blocks may result in damage to the drive and the voidance of
system warrantee.
It is imperative that you use protection blocks as designed and note the impact of altering these critical protections.
Security access levels and codes (trained Siemens personnel only)
Only Siemens trained personnel is authorized to change drive parameters.
Familiarize yourself with the following safety notes and preferentially contact Siemens technical support before changing the
default configuration.
CAUTION
Changing parameter values
Changes to parameter values may result in drive trip, instability or damage of the drive parts.
Do not change settings of any of the following parameters unless you are completely certain that the change is safe.
If the changes have to be done, make sure that while you change parameter settings the drive is not running and inhibit to
run.
NOTICE
Entering correct parameter values
Entering parameter values may impact drive functions severely.
Do not enter parameter values unless you are completely sure of the effect your changes will have.
You are responsible for providing correct parameter values.

34 A5E02417952B AF, 05/2012
Notes on maintenance and servicing
Maintenance General Maintenance Safety Instructions
Siemens has designed, built and tested the Perfect Harmony variable speed drive for long, trouble-free service. However,
periodic maintenance is required to keep the drive working reliably, to minimize system down time, and to maintain safety.
DANGER
ELECTRICAL HAZARD!
Handling the equipment with main input power connected will cause death or severe injuries.
Always switch off the main input power to the equipment before attempting inspection or maintenance procedure.
WARNING
Qualified Service Personnel
Incorrect handling and maintenance may cause death or severe injuries.
Ensure that only qualified service personnel maintain Perfect Harmony equipment and systems.
Maintenance and Earthing Procedure
Note
Because the Perfect Harmony is modular system, it has been marketed into various configurations of highly integrated
applications. Therefore, the following instructions may not cover all variations of equipment types or installation.
1. Stop drive operation, either through remote or local controls.
2. De-energize input voltage by opening incoming switchgear and locking to OPEN position with mechanical interlock.
Apply lock-out/tag-out principles as required by local code.
3. De-energize auxiliary control voltages and synchronous motor field/exciter controls.
4. Wait ten minutes to allow stored energy to dissipate from the Perfect Harmony drive.
5. If applicable, isolate motor connections by opening output switchgear using interlock key from input switchgear and
locking to OPEN position using mechanical interlock.
6. Observe the cell control board voltage LEDs by removing the interlock key from the input/output switchgear and opening
the Perfect Harmony cell sections door(s).
7. The LEDs are an indication of stored energy within the power cell capacitors (see Figure Indicators and Labels). If all
cell LEDs are extinguished, remove polyglass plates located behind the swing-out control box. Where available, use
ancillary AC voltage sensing devices to confirm the drive is de-energized.
8. Apply GREEN/YELLOW insulated ground cables from L1/L2/L3 and T1/T2/T3 to protective earth, P.E., with captive
fasteners.
9. Perform maintenance as required.
10. Remove GREEN/YELLOW insulated ground cables from L1/L2/L3 and T1/T2/T3 to protective earth, P.E.
11. Close Perfect Harmony doors in reverse sequence, and replace interlock key into input switchgear.
