Section 2 Safety information
About this chapterThis chapter contains safety information. Warning signs are presented which urge theuser to be careful during certain operations in order to avoid injuries to humans ordamage to equipment.
2.1 Warning signs
Strictly follow the company and country safety regulations. Workingin a high voltage environment requires serious approach to avoidhuman injuries and damage to equipment.
Do not touch circuitry during operation. Potentially lethal voltagesand currents are present.
Always avoid touching the circuitry when covers are removed. Theproduct contains electronic circuits which can be damaged if exposedto static electricity (ESD). Lethal high voltage circuits are alsoexposed when covers are removed.
Always use suitable isolated test pins when measuring signals in opencircuitry. Potentially lethal voltages and currents are present.
Never connect or disconnect a wire and/or a connector to or from aIED during normal operation. Hazardous voltages and currents arepresent that may be lethal. Operation may be disrupted and IED andmeasuring circuitry may be damaged.
Always connect the IED to protective earth, regardless of theoperating conditions. This also applies to special occasions such asbench testing, demonstrations and off-site configuration. Operating

the IED without proper earthing may damage both IED and measuringcircuitry and may cause injuries in case of an accident.
Never disconnect the secondary connection of current transformercircuit without short-circuiting the transformers secondary winding.Operating a current transformer with the secondary winding open willcause a massive potential build-up that may damage the transformerand may cause injuries to humans.
Never remove any screw from a powered IED or from a IEDconnected to powered circuitry. Potentially lethal voltages andcurrents are present.
Take adequate measures to protect the eyes. Never look into the laserbeam.
2.2 Caution signs
Always transport PCBs (modules) using certified conductive bags.Always handle modules using a conductive wrist strap connected toprotective ground and on a suitable antistatic surface. Electrostaticdischarge (ESD) may cause damage to the module since electroniccircuits are sensitive to this phenomena.
Do not connect live wires to the IED. Internal circuitry may bedamaged
Always use a conductive wrist strap connected to protective groundwhen replacing modules. Electrostatic discharge (ESD) may damagethe module and IED circuitry.
Take care to avoid electrical shock if accessing wiring and connectionIEDs when installing and commissioning.

5.4.3 Connecting the power supply moduleThe wiring from the cubicle terminal block to the IED terminals (see figure 23 forPSM connection diagram) must be made in accordance with the establishedguidelines for this type of equipment. The wires from binary inputs and outputs andthe auxiliary supply must be routed separated from the current transformer cablesbetween the terminal blocks of the cubicle and the IEDs connections. The connectionsare made on connector X11. For location of connector X11, refer to section "Rearside connectors".
5.4.4 Configuration for analog CT inputsThe secondary rated current of the CT (i.e. 1A or 5A) determines the choice of TRMin the IED. Two TRMs are available, One is dimensioned for an input current of 5Aand the other for an input of 1A. If the CT rated secondary current does not matchthe TRM input current rating adjustments can be made in settings depending on thetolerance of the TRM.
5.4.5 Connecting to CT and VT circuitsCTs and VTs are connected to the 24pole connector of the Transformer input module(TRM) on the rear side of the IED. Connection diagram for TRM is shown infigure 19.
Use a solid conductor with a cross section area between 2.5-6 mm2 (AWG14-10) ora 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 with20 A sockets must be used to connect the CT and VT circuits.Connectors X401 and X402 (for location see section "Rear side connectors") forcurrent and voltage transformer circuits are so called feed-through terminal blocksand are designed 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.
5.4.6 Connecting the binary input and output signalsAuxiliary power and signals are connected using voltage connectors. Signal wires areconnected to a female connector, see figure 31, which is then plugged into thecorresponding male connector, see figure 32, located at the rear of the IED. Forlocation of BIM, BOM, IOM and SOM refer to section "Rear side connectors".Connection diagrams for BIM, BOM, IOM and SOM are shown in figure 20,figure 25, figure26 and figure 27.If the IED is equipped with a test-switch of type RTXP 24 COMBIFLEX wires with20 A sockets, 1.5mm (AWG16) conductor area must be used to connect the auxiliarypower.

Procedure
1. Connect signals to the female connectorAll wiring to the female connector should be done before it is plugged into themale 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 0.2-2.5mm2 (AWG 24-14). If two conductors are used in the same terminal, themaximum 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 connected tothe same terminal, a ferrule must be used, see figure 33. This ferrule, is appliedwith the by Phoenix recommended crimping tool, see figure "". No solderingis needed. Wires with a smaller gauge can be inserted directly into the femaleconnector receptacle and the fastening screw shall be tightened with a torque of0.4 Nm (This torque applies to all binary connectors).
2. Plug the connector to the corresponding back-side mounted male connector3. Lock the connector by fastening the lock screws

5.5 Optical connections5.5.1 Connecting station communication interfaces (OEM and
SLM)The IED can, if ordered accordingly, be equipped with an optical ethernet module(OEM, see figure 22), needed for IEC 61850 communication and a serialcommunication module (SLM, see figure 22) for LON, SPA and IEC 608705103communication. In such cases optical ports are provided on the rear side of the casefor connection of the optical fibers. For location of OEM and SLM, refer tosection "Rear side connectors". 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
Section 5Installing the IED

-
optical ethernet module is used, the protection plate for the galvanic connectionmust not be removed.
Optical port X301: A, B (Tx, Rx) on the SLM module is used for SPA or IEC60870-5-103 communication. Connectors are of ST type (glass) or HFBR Snapin (plastic).
Optical port X301: C, D (Tx, Rx) on the SLM module is used for LONcommunication. Connectors are of ST type (glass) or HFBR Snap in (plastic).
Connectors are generally color coded; connect blue or dark grey cable connectors toblue or dark grey (receive) back-side connectors. Connect black or grey cableconnectors to black or grey (transmit) back-side connectors.
The fiber optical cables are very sensitive to handling. Do not bendtoo sharply. The minimum curvature radius is 15 cm for the plasticfiber cables and 25 cm for the glass fiber cables. If cable straps areused to fix the cables, apply with loose fit.Always hold the connector, never the cable, when connecting ordisconnecting optical fibers. Do not twist, pull or bend the fiber.Invisible damage may increase fiber attenuation thus makingcommunication impossible.
Please, strictly follow the instructions from the manufacturer for eachtype of optical cables/connectors.
5.5.2 Connecting remote communication interfaces (LDCM)The Line Data Communication Module (LDCM, see figure 22) is the hardware usedfor the transfer of binary and analog signal data between IEDs in different protectionschemes on the IEEE/ANSI C37.94 protocol. The optical ports on the rear side of theIED are X302, X303, X312 and X313. For location of LDCM module, refer tosection "Rear side connectors".
