4. General
Work on live equipment must be done only by duly qualified and trained staff.
Unconditionally pay attention to following points:
• Never touch live parts.
• Only use suitable tools and proper measuring instruments according to the protection classes (I, II, III or
IV).
• Take care of correct work clothes and eye protection.
• Work on live equipment must be done only under attendance of a second skilled person.
• For human protection an insulated, non-grounded mat has to be used.
Please also see the safety directives of EN 50110 "Work on electric installations below 1 kV AC and
1.5 kV DC".
Generally defect units are replaced by exchange devices.
All >pDRIVE< MX eco & pro up to 18.5 kW have a compact power part and therefrom they are typically
replaced as a whole. Exceptions are the Matrix operating panel BE11, option cards used and fans.
HTSI
All >pDRIVE< MX eco & pro from 22 kW are designed in such a way, that service can be done on module level.
For devices from 90 kW an additional tool for removing and fitting (>pDRIVE< "Exchange tool") is supplied,
which is returned after exchange together with the defect inverter.
Please consult our competent service experts in case of severe faults, which cannot be solved by
8 P01 035 EN.01/01
means of this instruction.
Before exchanging defect parts or fuses, the cause of fault must be found. Exchanging parts without
eliminating the cause of fault leads to a new breakdown and may even enlarge the dimension of
damage.
Check as well the ambient conditions before exchanging defect parts or the whole device. See also
chapter "Environmental influences", page 4.

5. Identification of the device
It is important to identify the respective device on the basis of type and serial number in case of maintenance
and repair. These information are required especially when contacting the service department or ordering
spare parts.
There are two possibilities to identify a device:
1. Read off the data on the name plate of the device.
The name plate is always placed on the lower right sight of the housing.
2. Read off the values of parameter F1
These information are absolutely necessary for maintenance and repair:
Type: Name plate or F1.01
Serial no.: Name plate or F1.05
HTSI
8 P01 035 EN.01/01
Storage
Storage temperature -25°C to 70°C
In case of storage times up to 3 years no special treatment of the frequency inverter is necessary due to the
comparatively low sharing resistors.
In order to guarantee the life cycle we recommend applying voltage to the inverter for about 1 hour before
pulse enable takes place. This process is also called forming the electrolytic capacitors !!
3
6. Environmental influences
The frequency inverters >pDRIVE< MX eco & pro provide the following protection degree as standard:
>pDRIVE< MX eco & pro up to 75 kW from 90 kW
Front and sideways IP21 IP31
Top IP41, IP20 without protective cover 4V: IP20, IP31 with DCL box
6V: IP20, IP31 with TRAFO-BOX
Bottom IP21 IP00, IP31 with terminal box
The cooling channel of the power part is separated from the control electronics for all devices and corresponds
with IP54.
If a higher protection degree is desired or required, additional measures have to be taken (e.g. installation in a
cubicle).
The permissible pollution degree of the environment is pollution degree 2 according to EN 61800-5-1 for the
whole power range.
According to EN 60721-3-3 the following applies up to 75 kW Class 3C1 and 3S2
from 90 kW: Class 3C2 and 3S2
Use of frequency inverters in waste water treatment plants
HTSI
Sewage gases may contain ammoniac which cause oxidation of bright copper. In this case, components of the
control and power electronics will corrode and this leads to a malfunction of the device !
Use of frequency inverters in dust polluted environment (e.g. waste incineration plants)
Please be aware of the risk of conductive (metal-)dust and the impact on the inverter electronics. Conductive
8 P01 035 EN.01/01
dust causes short circuit of components and thus results in damage.
Use of frequency inverters in the vicinity of crushing plants
Please observe that dust is produced in varying size and consistence in the vicinity of crushing plants (e.g.
shredders). The use of the inverters has to take place in that way, that a contamination with dust is impossible.
Condensation
Generally the operation of the frequency inverter in condensing environment is forbidden. Also condensation
without mains voltage supply causes in interaction with dust (e.g. at chalk-pits) oxidation of copper (even
through solder resist).
Correctives in case of the described environmental influences may be:
• Installation of the frequency inverters aloof from contaminated areas.
• Cooling air for the inverter supplied from a clean area through a separated air flow channel (overpressure
ventilation).
• Appropriate high protection degree of the cubicle (take care of sufficient cooling!).
4
7. If the frequency inverter is operated outside the specification, warranty claim expires !!!
This applies for example in case of:
• Conductive dust
• Humidity and condensation
• Aggressive atmosphere
• Operation outside the specified temperature range
• Non-compliance with pollution degree 2 according to EN 61800-5-1
Application remarks
The use of the >pDRIVE< MX eco & pro frequency inverters is basically in all mains variants permitted. But
>pDRIVE< MX pro 6V devices must not be operated in "Corner Grounded Networks".
For nongrounded mains (typical for industrial mains) the built-in radio frequency interference filter has
to be adapted by means of switch-over/reconnection. In this case the maximal allowed pulse
frequency is 4 kHz.
Please observe the remarks in chapter "Nongrounded mains" of the corresponding mounting
instructions !
HTSI
Switching between motor and inverter reduces the life cycle of the power part. Therefore the frequency inverter
must be locked with impulse inhibit first and after switching it has to be enabled delayed or set parameter
C6.08 "Motor contactor control" to "1 .. VSD controlled" or "2 .. External control".
8 P01 035 EN.01/01
Avoid the use of reversing contactors to change the rotational direction. If avoiding is not possible, at least an
interlock with the inverter has to be provided !
Motors with attached magnetic spring-loaded brake must be supplied externally and not from the inverter
output !
Fans of forced ventilated motors must be supplied externally and not from the motor terminal box !
5
8. Factory setting
Macros are factory presettings of the parameters for typical applications of the >pDRIVE< MX eco & pro. When
loading a macro, the application data in the EEprom are overwritten. Parameter groups such as motor data,
language setting, fault memory, operating hours, texts and basic communication settings as well as the
parameter settings stored in the "Backup" remain unchanged.
Using parameter B2.02 "Macro selection", the parameter settings according to the selected macro are loaded
into the device memory.
The macro M1 corresponds to the factory setting.
The following parameters are not reset by loading a macro:

Reset of the fault memory
The whole fault memory can be canceled by entering "7635" in parameter F6.05 Service code. In this way
important information for analysis of faults get lost and thus this function should only be used in exceptional
cases.
Reset of operating hours meters
All operating hours meters can be canceled by entering "1966" in parameter F6.05 Service code. In this way
important information for analysis of faults get lost and thus this function should only be used in exceptional
cases.
In parameter F6.05 Service code only codes described in these instruction may be entered. Otherwise
malfunction and loss of guarantee may occur.

9. Motor data
Each >pDRIVE< MX eco & pro frequency inverter provides factory motor data according to its power.
These motor data are the basis for operating the frequency inverter but usually they are adjusted by entering
the data of the rating plate or they are improved by the determined autotuning data.
When changing a motor parameter the autotuning data get lost. That means that autotuning has to be
executed again after each change of a motor parameter!

12. Maintenance
The frequency inverters >pDRIVE< MX eco & pro are low-maintenance units and contain no moving parts
except the fans. The maintenance intervals depend on the power-on time (0...24 h) and the environmental
conditions of the plant (influences by application and environment).
Visual inspection
During visual inspection the overall condition of the inverter installation should be checked for following points:
− Mechanical damages of the housing
− Traces of oxidation caused by humidity, aggressive gases or liquids
− Dust sedimentation inside the inverter, especially conductive dust
− Dirt and dust sedimentation on the heat sink and the motor terminal board
− Damages of cable isolation (especially at the inverter lead-through)
− Take the actual parameter settings and compare them with the commissioning settings
Cleaning the heat sink
HTSI
Parameter A3.05 "Thermal load VSD" shows the thermal balance which arises from the two factors load and
cooling conditions. If the thermal load reaches 105 %, a fault shut-down "Inverter over temperature" occurs.
Reset can be done if the thermal load is below 80 % again.
If parameter A3.05 reaches high values (values near 100 %) even at low load and ambient temperature,
8 P01 035 EN.01/01
it is necessary to clean the heat sink and to check the cooling conditions.
Cooling air holes and filter mats
If the inverters are mounted in a cubicle, the cooling air holes and filter mats, if existing, have to be regularly
checked and exchanged.
Removing the filter mats enables intrusion of dangerous substances, which leads to loss of warranty
claim in case of damage !
10
13. Maintenance of fans
The frequency inverters up to >pDRIVE< MX eco 4V110, MX pro 4V90/110 and MX pro 6V75/90 contain DC
fans for cooling the power part and the control part.
The inverters from >pDRIVE< MX eco 4V132, MX pro 4V110/132 and MX pro 6V90/110 contain DC fans for
cooling the control part and AC fans for cooling the power part.
The fans of the power part are switched off during impulse inhibit or low load if parameter B3.41 "Fan control"
is set appropriate.
Life cycle of DC-fans: approx. 30.000 hours
Life cycle of AC-fans: approx. 48.000 hours
The ambient condition has an effect on the life cycle of the fans.
Parameters A5.10 "Operating hours fan" and A5.12 "Interval counter fan" show the actual operating time of the
AC fans in the display. By means of parameter A5.11 "Interval fan" a maintenance message can be released
after reaching a preset operation time.
The fans for the control part start running as soon as the inverter is applied with voltage. Therefore
these fans should be replaced precautionary after five years!
Exchanging the control part fans
HTSI
The fans for the control part are 24 V DC fans and are located in the upper part of the inverter (see chapter
"Plans", page 69). Depending on the power the devices are equipped with one to four fans for the control part,
marked with M10, M11, M12 and M13.
When exchanging a fan from >pDRIVE< MX eco 4V160, MX pro 4V132/160 and MX pro 6V90/110 you have to
8 P01 035 EN.01/01
pull the connected plug X30, X31, X32 or X33 and to loosen the four screws. For mounting the new fan
proceed in reverse order.
The drawing shows as example the control part fan and the
corresponding plug for a >pDRIVE< MX eco 4V160. To all other
power ratings the description applies analogously.
11
14. Exchanging the power part fans
The power part fans are 400 V AC fans and located below the terminal panel on the lower end of the inverter
(see chapter "Plans", page 69). Depending on the power the devices are equipped with one to four fans for the
power part, marked with M1, M2, M3 and M4.
Basically there are two ways to exchange the power part fans:
Exchange from the bottom
For this easy and quick method access from below is required. Possibly the mains and motor cables have to
be disconnected therefor.
1. Pull off the plug of the fan to be exchanged and thread the cables including the grommet through the
terminal panel.
2. Loosen both fixing screws of the fan in the lower end of the inverter approx. 5 mm but do not remove.
3. Lift up the fan and pull it out downwards.
4. Insert the new fan from the bottom, making sure that the upper folding plate sticks into the provided hole.
5. Check whether the gaskets are placed in the right way between the fan and the heat sink.
6. Fasten both fixing screws of the fan in the lower end of the inverter.
7. Thread the plug of the fan and the grommet through the terminal panel and insert the grommet in the right
way again.
8. Finally connect the plug of the fan again.
HTSI
Exchange from the front
In this case no access from the bottom is required. This is advantageous e.g. when the terminal box TER-BOX
is used.
1. Pull off the plugs of all power fans and thread the cables including the grommet through the terminal panel.
8 P01 035 EN.01/01
2. Unscrew all internal power connections (see following drawing).
3. Unscrew all mains connections (L1, L2, L3) and motor connections (U, V, W).
4. Remove the control cables by pulling-off the terminals and the cable conduit on the right-hand side.
5. Unplug following plugs:

X3 (6.3 mm, violet), X13 (4.8 mm, violet)
6. Unscrew the earth screw on the left inner wall (see following drawing).
7. Unscrew the 6 screws of the terminal panel and lift it to the front.
8. Loosen both fixing screws of the fan(s) in the lower end of the inverter approx. 5 mm but do not remove.

General advice for troubleshooting:
• If a fault occurs during commissioning, the reason is in all probability an external fault because the
inverters are checked for full functionality before delivery.
• When a fault occurs after some time in operation, the reason could be either an external fault or an
inverter fault.
