Overview Chapter 3
1 Overview
Most of the IED 670s can be rack, flush or wall mounted with the use of different mounting kits,
see figure2. An additional box of type RHGS can be mounted to one side of a 1/2 or 3/4 IED.
The different mounting kits contain all parts needed including screws and assembly instructions.
The following mounting kits are available:
• Flush mounting kit
• 19” Panel (rack) mounting kit
• Wall mounting kit
• Side-by-side mounting kit
The same mounting kit is used for side-by-side rack mounting and side-by-side flush mounting.
Note!
The mounting kits must be ordered separately when ordering an IED. They are available as op-
tions on the ordering sheet in “Accessories for IED 670”, see section 1.3 "Related documents"
on page 2.
Generally, all the screws included in delivered mounting kits are of Torx type and a
screwdriver of the same type is needed (Tx10, Tx15, Tx20 and Tx25).
Note!
If other type of screws are to be used, be sure to use the dimensions of the screws that are given
in this guide.

3.1 Overview
All IED sizes, 1/2 x 19”, 3/4 x 19” and 1/1 x 19” and RHGS6 6U 1/4 x 19”, cases, can be flush
mounted. Only a single case can be mounted in each cut-out on the cubicle panel, for class IP54
protection.
The flush mounting kit are utilized for IEDs of sizes: 1/2 x 19”, 3/4 x 19” and 1/1 x 19” and are
also suitable for mounting of RHGS6, 6U 1/4 x 19” cases.
Note!
Flush mounting cannot be used for side-by-side mounted IEDs when IP54 class must be fulfilled.
Only IP20 class can be obtained when mounting two cases side-by-side in one (1) cut-out.
Note!
To obtain IP54 class protection, an additional factory mounted sealing must be ordered when
ordering the IED.

1. Cut an opening in the panel.
See section 3.4 "Flush mounting dimensions" on page 20 regarding di-
mensions.
2. Carefully press the sealing strip around the IEDs collar. Cut the end
of the sealing strip a few mm to long to make the joining point (5)
tight.
The sealing strip is delivered with the mounting kit. The strip is long
enough for the largest available IED.
3. Insert the IED into the opening (cut-out) in the panel.
4. Attach the fasteners to the IED.
Insert the panel end of the fastener in the gap between the IED and the
panel. Insert the rear end of the fastener into the groove. Insert from the
rear side and lightly tighten the screw (4)
Repeat this with the remaining fasteners.
5. Fix the IED by tightening all four (7) screws against the panel.

19” panel rack mounting Chapter 3
4 19” panel rack mounting
4.1 Overview
All IED sizes can be mounted in a standard 19” cubicle rack by using the for each size suited
mounting kit which consists of two mounting angles and fastening screws for the angles. The
mounting angles are reversible which enables mounting of IED size 1/2 x 19” or 3/4 x 19” either
to the left or right side of the cubicle.
Note!
Please note that the separately ordered rack mounting kit for side-by-side mounted IEDs, or
IEDs together with RHGS cases, is to be selected so that the total size equals 19”.
Note!
When mounting the mounting angles, be sure to use screws that follows the recommended di-
mensions. Using screws with other dimensions than the original may damage the PCBs inside
the IED.

6. Place the IED assembly in the rack.
Table 5: Side-by-side mounting kit
6.4 IED 670 mounted with a RHGS6 case
An 1/2 x 19” or 3/4 x 19” size IED can be mounted with a RHGS (6 or 12 depending on IED
size) case. The RHGS case can be used for mounting a test switch of type RTXP 24. It also has
enough space for a terminal base of RX 2 type for mounting of, for example, a DC-switch or two
trip relays.
The side-by-side mounting kit consists of 2 mounting plates (pos 1 in figure 15 "Side-by-side rack mount-
ing details." on page 29), fixing screws (pos 2 and 3 in figure 15 "Side-by-side rack mounting details." on
page 29) and assembly instruction.
The side-by-side mounting kit does not include mounting angles or fixing screws for rack mounting. Appli-
cable rack mounting kit, depending on total size of IEDs or test switches mounted side-by-side, must
therefore be ordered separately according to table 2 "Rack mounting kit" on page 23.
When ordering an IED of 1/2 or 3/4 x 19" and a RTXP24 test switch module, the test switch is mounted in
a RHGS 6 case which can be mounted side-by-side to the IED. A side-by-side mounting kit is included
when ordering a test switch module.

Side-by-side flush mounting Chapter 3
7 Side-by-side flush mounting
7.1 Overview
It is not recommended to flush mount side by side mounted cases if IP54 is required. If your ap-
plication demands side-by-side flush mounting, the side-by-side mounting details kit and the 19”
panel rack mounting kit must be used. The mounting kit has to be ordered separately. The max-
imum size of the panel cut out is 19”.
Note!
With side-by-side flush mounting installation, only IP class 20 is obtained. To reach IP class 54,
it is recommended to mount the IEDs separately. For cut out dimensions of separately mounted
IEDs, see section 3 "Flush mounting" on page 17.
Note!
When mounting the plates and the angles on the IED, be sure to use screws that follows the rec-
ommended dimensions. Using screws with other dimensions than the original may damage the
PCBs inside the IED.

Connecting to protective earth Chapter 4
1 Connecting to protective earth
Connect the earthing screw (pos 1 in figure 20) on the rear of the IED unit to the closest possible
earthing point in the cubicle. Electrical codes and standards require that protective earth cables
are green/yellow conductors with a cross section area of at least 2.5 mm2
(AWG14). There are
several protective earthing screws on an IED. The Power supply module (PSM), Transformer
input modules (TRM) and the enclosure are all separately earthed, see figure 20 below.
The cubicle must be properly connected to the station earthing system. Use a conductor with a
core cross section area of at least 4 mm2
(AWG 12).
Figure 20: Rear view of IED with one TRM showing earthing points.

Note!
Use the main protective earth screw (1) for connection to the stations earthing system. Earthing
screws for PSM module (2) and TRM module (3) must be fully tightened to secure protective
earth connection of these modules.

39
Connecting the power supply module Chapter 4
2 Connecting the power supply module
The wiring from the cubicle terminal block to the IED terminals (see figure 34 on page 64 for
PSM connection diagram) must be made in accordance with the established guidelines for this
type of equipment. The wires from binary inputs and outputs and the auxiliary supply must be
routed separated from the current transformer cables between the terminal blocks of the cubicle
and the IEDs connections. The connections are made on connector X11. For location of connec-
tor X11, refer to section 3 "Rear side connectors" on page 58.

40
Connecting to CT and VT circuits Chapter 4
3 Connecting to CT and VT circuits
CTs and VTs are connected to the 24–pole connector of the Transformer input module (TRM)
on the rear side of the IED. Connection diagram for TRM is shown in figure 29 on page 61.
Use a solid conductor with a cross section area between 2.5-6 mm2 (AWG14-10) or a stranded
conductor with a cross section area between 2.5-4 mm2
(AWG14-12).
If the IED is equipped with a test-switch of type RTXP 24 COMBIFLEX wires with 20 A sock-
ets must be used to connect the CT and VT circuits.
Connectors X401 and X402 (for location see section 3 "Rear side connectors" on page 58) for
current and voltage transformer circuits are so called “feed-through terminal blocks” and are de-
signed for conductors with cross sectional area up to 4 mm2
(AWG 12). The screws used to
fasten the conductors should be tightened with a torque of 1Nm.

41
Connecting the binary input and output signals Chapter 4
4 Connecting the binary input and output signals
Auxiliary power and signals are connected using voltage connectors. Signal wires are connected
to a female connector, see figure 21, which is then plugged into the corresponding male connec-
tor, see figure 22, located at the rear of the IED. For location of BIM, BOM and IOM refer to
section 3 "Rear side connectors" on page 58. Connection diagrams for BIM, BOM and IOM are
shown in figure 30, figure 36 and figure 32 on page 63.
If the IED is equipped with a test-switch of type RTXP 24 COMBIFLEX wires with 20 A sock-
ets, 1.5mm2
(AWG16) conductor area must be used to connect the auxiliary power.
Procedure
1. Connect signals to the female connector
All wiring to the female connector should be done before it is plugged
into the male part and screwed to the case. The conductors can be of rigid
type (solid, stranded) or of flexible type.
The female connectors accept conductors with a cross section area of
0.2-2.5 mm2
(AWG 24-14). If two conductors are used in the same ter-
minal, the maximum permissible cross section area is 0.2-1 mm2 (AWG
24-18 each).
If two conductors, each with area 1.5 mm2
(AWG 16) need to be connect-
ed to the same terminal, a ferrule must be used. It is recommended to use
Phoenix ferrules Al-Twin2 1,5-8 BK, Phoenix part No 32 00 82-3, see
figure 23. This ferrule, is applied with the by Phoenix recommended
crimping tool, Phoenix part No 12 06 36 6, see figure 24. No soldering is
needed. Wires with a smaller gauge can be inserted directly into the fe-
male connector receptacle and the fastening screw shall be tightened with
a torque of 0.4 Nm (This torque applies to all binary connectors).
2. Plug the connector to the corresponding back-side mounted male
connector
3. Lock the connector by fastening the lock screws

Making the screen connection Chapter 4
5 Making the screen connection
When using screened cables always make sure screens are earthed and connected according to
applicable engineering methods. This may include checking for appropriate earthing points near
the IED, for instance, in the cubicle and/or near the source of measuring. Ensure that earth con-
nections are made with short (max. 10 cm) conductors of an adequate cross section, at least 6
mm2 (AWG10) for single screen connections.

Overview Chapter 5
Optical connections
1 Overview
Each IED is provided with a communication interface, enabling it to connect to one or many sub-
station level systems or equipment, either on the Substation Automation (SA) bus or Substation
Monitoring (SM) bus.
Following communication protocols are available:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
Theoretically, several protocols can be combined in the same IED.

Optical connections
2 Connecting station communication interfaces
(OEM and SLM)
The IED can, if ordered accordingly, be equipped with an optical ethernet module (OEM, see
figure 33 on page 63), needed for IEC 61850 communication and a serial communication mod-
ule (SLM, see figure 33 on page 63) for LON, SPA and IEC 60870–5–103 communication. In
such cases optical ports are provided on the rear side of the case for connection of the optical
fibers. For location of OEM and SLM, refer to section 3 "Rear side connectors" on page 58.
• Optical ports X311: A, B (Tx, Rx) and X311: C, D (Tx, Rx) on the OEM module
are used for IEC 61850 communication. Connectors are of ST type. When the op-
tical ethernet module is used, the protection plate for the galvanic connection
must not be removed.
• Optical port X301: A, B (Tx, Rx) on the SLM module is used for SPA or IEC
60870-5-103 communication. Connectors are of ST type (glass) or HFBR Snap
in (plastic).
• Optical port X301: C, D (Tx, Rx) on the SLM module is used for LON commu-
nication. Connectors are of ST type (glass) or HFBR Snap in (plastic).
Connectors are generally color coded; connect blue or dark grey cable connectors to blue or dark
grey (receive) back-side connectors. Connect black or grey cable connectors to black or grey
(transmit) back-side connectors.
Caution!
The fiber optical cables are very sensitive to handling. Do not bend too sharply. The minimum
curvature radius is 15 cm for the plastic fiber cables and 25 cm for the glass fiber cables. If cable
straps are used to fix the cables, apply with loose fit.
Always hold the connector, never the cable, when connecting or disconnecting optical fibers. Do
not twist, pull or bend the fiber. Invisible damage may increase fiber attenuation thus making
communication impossible.
Note!
Please, strictly follow the instructions from the manufacturer for each type of optical ca-
bles/connectors.

Test switch modules
1 Overview
The test switch RTXP 24, see figure 38, is used to make it possible to test an IED in a fail-safe
way. Inserting the test-plug handle, see figure 37, into the test switch automatically makes all
preparations for a secure test in proper sequence. Blocking trip circuits, short circuit CT's and
opening voltage circuits makes the IED available for secondary injection testing.
The Test switch module is to be ordered as an accessory when ordering the IED, see section “Or-
dering” in “Accessories for IED 670”. Ordering number for the different test switches,
DC-switch and mounting accessories can also be found in section 2 "Ordering details" on page
69.
As a option, a COMBIFLEX DC-switch can be ordered and mounted in one of the two seats RX
2 terminal base, see figure 39. The RX 2 terminal base can also be used for e.g. additional trip-
ping relays and reduce the cost for an additional case or rack.
Each test switch RTXP 24 is equipped with a signal contact no 29–30, located at the top on right
hand housing (see section 3 "Test switch configurations" on page 71.. This contact is used for
signaling of test in progress, which is very important especially during test of differential pro-
tections.

Note!
20A COMBIFLEX terminal sockets (2658 636-1) and multi stranded and tinplated wire of 2.5
mm2 must be available for connection of the IED to the test switch module.
Note!
For connection of contacts 29 and 30, a multi stranded and tinplated wire of 1.5mm2 and 10A
terminal sockets (2658 634-1) are needed.

2 Ordering details
Selection of a RTXP 24 test switch for each ordered test switch module is required. See appli-
cable IED Buyer's guide for recommendations. Please refer to section “Related documents”.
Table 13: Test switch
The test switch module consists of a RHGS 6 case including a RTXP 24 test switch and if no other options
are selected an empty two seat COMBIFLEX terminal base RX2 is mounted at the lower part of the mod-
ule (see figure 39 "A typical test switch module with a RTXP 24 and a optional DC-switch mounted in one
RX 2 terminal base" on page 68).
A side-by-side mounting kit (see table 5 "Side-by-side mounting kit" on page 30) is always included in the
delivery of a test switch module. To flush mount side-by-side mounted test switches, the separately
ordered 1/1 x 19” rack mounting kit shall be used. To rack mount side-by-side mounted test switches
applicable rack mounting kit, to reach 19”, shall be used (see table 2 "Rack mounting kit" on page 23).
Observe that cut-outs in panel must be made according to dimensions given for side-by-side flush mount-
ing (see table 7.4 "Side-by-side flush mounting dimensions" on page 34
When ordering an IED 670 (all sizes) and a test switch module, the test switch module will be delivered
separately, neither mounted side-by-side or wired to the IED.

Test switch modules
4 4U 19” rack mounting of test switches
If the cubicle assembly consists of more than one IED 670 and needs more than one test switch
totally, it can be advantageous to mount up to four test switches in a 4U 19” rack by using the
side-by-side mounting kit instead of mounting each test switch in a separate RHGS 6 case. A
distance of min. 1C (7mm) is required between each test switch in order to allow for the opening
of the cover locks, see figure 49 and figure 50.

Mounting in cubicles
Chapter 9 Mounting in
cubicles
About this chapter
This chapter describes the mounting of units in cubicles.

78
Overview Chapter 9
1 Overview
The cubicle’s design shall take into account all the electrical and environmental demands arising
from the location of the cubicle.
The cubicle should be designed according to the international standard publication IEC 439-1
and to other IEC publications referring to this standard.
Degrees of protection as per IEC 60 529: IP21, IP41, IP43 or IP54.
The earthquake protection of the cubicle should follow the standard, IEEE 693 draft 5.

79
Requirements Chapter 9
2 Requirements
2.1 Degrees of protection
The IEC 60 529 describes standard degrees of protection provided by enclosures (IP code) that
a product is designed to provide when properly installed.
2.1.1 Identification examples using the IP code
The explanation of the Alpha-numeric IP code system can be illustrated as shown in figure 51.
Figure 51: Explanation of the Alpha-numeric IP code system
Using the IP code according IEC 60 529, the degrees of protection of the equipment are IP21,
IP41, IP43 or IP54. The IP code components are described in table 16.

2.2 Environmental aspects
The cubicle can be equipped with thermostat (figure 52) controlled heating elements (figure 53)
to prevent condensation. Normal cubicles are designed and fitted for indoor use in a dry envi-
ronment or at a reasonable humidity and air pollution level.
2.3 Earthquake protection
The standard IEEE 693 draft 5 states recommended practice for seismic design of substations.
The cubicle should be able to sustain a maximum ground acceleration (ZPA) equivalent to 0.5g
in areas with a high risk for seismic shocks.
2.4 Power losses
The temperature rises in a cabinet due to the power losses from the equipment housed in it. It
also depends on the cabinet’s degree of protection (airtightness). Self-ventilated cooling is also
highly dependent on the type of equipment involved and its location in the cabinet.
Equipment placed to ensure free air circulation around a heat source can be expected to emit
more heat for the same increase in temperature than equipment which is not so well situated. Ex-
pected power losses at certain permissible temperature rises can also only be given as guidelines
as shown in figure 54, figure 55 and figure 56.

Figure 56: Temperature rise, IP54 (sealed cubicle)
2.5 Ambient temperature
2.5.1 Maximum permissible ambient temperature
The relays are designed for a maximum ambient temperature of 55°C at 110% of rated voltage.
The permissible ambient temperature stated for a relay refers to the average temperature sur-
rounding the relay itself and not the temperature in the control room, where the relay’s cubicle
or panel is located.
If a relay is mounted in a cubicle, case or other sealed enclosure, consideration must be given to
the increase in temperature, resulting from the power losses in the equipment.
2.5.2 Permissible temperature increase
The maximum permissible ambient temperature for relays mounted in a case or cubicle is, in
reality, less than the specified 55°C due to temperature rises in the case and cubicle.
The temperature rise must be considered when designing control rooms. The temperature rise
for the room ambient temperature compared to the relay ambient temperature could be as high
as 15°C if the maximum permissible power losses given in table 17 are applicable.
The actual power losses will generally be less than the maximum permissible values and the
temperature rise will be less than 15°C. With the maximum permissible room ambient temper-
ature corresponding to +55°C, the permissible relay ambient temperature could be +40°C.

83
If the room temperature is higher, it is necessary to keep the increase less than 15°C. This can
be achieved either by mounting the equipment in several cubicles or cases in order to reduce the
supplied power losses per cubicle or case, or by improving cooling through increased natural
ventilation or by forced ventilation using a fan.
The total power losses of the relays incorporated in a case or cubicle are usually too low to cause
a 15°C temperature increase. However, there are two situations when it may be necessary to ob-
serve the total power losses and to rearrange the relaying equipment. It may then also be neces-
sary to reduce the total losses per frame or cubicle.
The first situation is when the auxiliary voltage supply is 220 or 250 V dc for several voltage or
current measuring relays (2-3 pcs) with a fairly high power consumption, positioned in the same
equipment frame or in equipment frames mounted close to each other. It is not possible to fill all
positions in a cubicle or a rack or otherwise to pack the above relays too closely and still stay
within the 15°C rise in the air surrounding the relay.
The second situation concerns auxiliary relays. There is a limitation to the numbers of continu-
ously energized auxiliary relays that may be included in a RHGS or RHGX case or equipment
frame and still stay within the 15°C rise limit. For example in an application of continuously en-
ergized interposing relays. It is the temperature rise rather than the physical space which may
limit the number of relays in a case or frame.
2.5.3 Permissible power losses
Concerning permissible relay power losses in cases of type RHGS or RHGX, consideration must
be given to how the case is mounted when defining the permissible power losses.
Example: When a case is flush-mounted at the front of a cubicle
1. Take the calculated temperature increase within the case
2. Add the temperature increase of the air in the cubicle
3. Calculate the total temperature increase in the case in relation to room tempera-
ture
Relaying equipment in cubicle
Table 17 states the recommended values of permissible power losses of relaying equipment
mounted in the D-plane (hinged frame or front plane) and the B-plane (rear mounting plane).
2.5.4 Temperature rise
A calculation of the temperature rise within an RHGS or RHGX case mounted in a cubicle is
shown in equation 1.
Note!
It is recommended to mount only transformers, resistors and similar apparatuses in the B-plan.
It is not recommended to mount relays in the B-plane, as the air circulation is minimal.

distributed over the whole equipment frame.
2)
Also applicable to equipment frames mounted close to each other if every alternate equipment
frame has a low continuous power loss (approximately 5 W). It is desirable to mount the equip-
ment frames in the cubicles with maximum possible space between them, to ensure the best pos-
sible heat dissipation.
3)
The heater should be disconnected by a thermostat set for maximum 45°C.

2.5.5 Self-ventilated design of the cubicle
Figure 57: Self ventilated design of the cubicle
Table 17 is applicable for convection in sealed or self-ventilated cubicles with a design accord-
ing to figure 57. When the power losses are approximately evenly distributed in the equipment
frames, the temperature increase should not exceed 15°C.
Sources of maximum heat loss, such as power supplies for static relays and continuously ener-
gized auxiliary relays, should preferably not be located too close to each other. They should be
located with the maximum possible spacing, to ensure the lowest possible temperature in the sur-
rounding air.
The equipment frames containing relays with the highest power losses should preferably be po-
sitioned as far down as possible in the cubicle.
The temperature increase should be calculated when designing the layout of relaying equipment.
This is done by adding the power losses at rated voltage for all the relays in the cubicle that are
simultaneously energized including auxiliary relays, and comparing the calculated values with
those in table 17. Normally, it is sufficient to calculate with only the power losses of the auxil-
iary voltage supply for the static and numerical relays and thus to ignore the losses of signal cir-
cuits.

The power losses in table 17 shall be calculated based on the losses at 110% of rated voltage, as
obtained from the technical data tables (refer to the Buyer's Guide for the respective relay type).
The temperature rise of 15°C has, however, been based on the relays operating at their maximum
permissive voltage. For relays operating at their rated voltage the permitted losses in table 17
will result in a temperature rise less than that specified.

All units in the cubicle shall be earthed through the cubicle framework. All units must be well
fixed and the screws tightened correctly.
Equipment with a connector (possibly a screw) for protected earth shall be connected to the
earthing bar in the cubicle with a green/yellow cable. The minimum cross section area of the
conductor shall be selected according to the maximum power supply or a minimum cross section
area of 1.5 mm2.
Figure 58: Equipment label, marking the connection point for protective earth
For a cubicle with a hinged frame, the frame shall be earthed to the cubicle frame with two
green/yellow wires, each with a minimum cross section area of 6 mm2
. One of the wires shall
be mounted at the top and the other to the bottom of the cubicle.

A vertical earthing bar (see figure 60), size 12 x 3 mm, or a horizontal earthing bar (see
figure 61), size 30 x 10 mm, shall be installed in the base of the cubicle.

89
When two or more cubicles are mounted side-by side, the earthing bars shall be joined together
with joining pieces, see figure 62. The earthing bar is then connected to an earth grid, or equiv-
alent, in the plant.

Overreach A term used to describe how the relay behaves during a fault condition.
For example a distance relay is over-reaching when the impedance pre-
sented to it is smaller than the apparent impedance to the fault applied
to the balance point, i.e. the set reach. The relay “sees” the fault but per-
haps it should not have seen it.

TCP Transmission control protocol. The most common transport layer proto-
col used on Ethernet and the Internet.
TCP/IP Transmission control protocol over Internet Protocol. The de facto stan-
dard Ethernet protocols incorporated into 4.2BSD Unix. TCP/IP was
developed by DARPA for internet working and encompasses both net-
work layer and transport layer protocols. While TCP and IP specify two
protocols at specific protocol layers, TCP/IP is often used to refer to the
entire US Department of Defense protocol suite based upon these,
including Telnet, FTP, UDP and RDP.

Underreach A term used to describe how the relay behaves during a fault condition.
For example a distance relay is under-reaching when the impedance
presented to it is greater than the apparent impedance to the fault
applied to the balance point, i.e. the set reach. The relay does not “see”
the fault but perhaps it should have seen it. See also Overreach.

UTC Coordinated universal time. A coordinated time scale, maintained by the
Bureau International des Poids et Mesures (BIPM), which forms the
basis of a coordinated dissemination of standard frequencies and time
signals. UTC is derived from International Atomic Time (TAI) by the addi-
tion of a whole number of "leap seconds" to synchronize it with Universal
Time 1 (UT1), thus allowing for the eccentricity of the Earth's orbit, the
rotational axis tilt (23.5 degrees), but still showing the Earth's irregular
rotation, on which UT1 is based. The Coordinated Universal Time is
expressed using a 24-hour clock and uses the Gregorian calendar. It is
used for aeroplane and ship navigation, where it also sometimes known
by the military name, "Zulu time". "Zulu" in the phonetic alphabet stands
for "Z" which stands for longitude zero.
