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

Section 2Safety information


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.



Changing the active setting group will inevitably change the IEDsoperation. Be careful and check regulations before making thechange.

2.3 Note signs

The protection assembly is designed for a maximum continuouscurrent of four times rated value.



Section 3 Overview

About this chapterThis chapter outlines the installation and commissioning of the IED.

3.1 Commissioning and installation overviewThe settings for each function must be calculated before the commissioning task canstart. A configuration, done in the configuration and programming tool, must also beavailable if the IED does not have a factory configuration downloaded.The IED is unpacked and visually checked. It is preferably mounted in a cubicle oron a wall. The connection to the protection system has to be checked in order to verifythat the installation is successful.

Section 3Overview


Section 4 Unpacking and checking the IED

About this chapterThis chapter describes the delivery and the unpacking of the IED

4.1 Taking delivery, unpacking and checkingProcedure

1. Remove the transport casing.2. Visually inspect the IED.3. Check that all items are included in accordance with the delivery documents.

Once the IED has been started make sure that the software functions orderedhave been included in the delivery.

4. Check for transport damages.If transport damage is discovered appropriate action must be taken against thelatest carrier and the nearest ABB office or representative should be informed.ABB should be notified immediately if there are any discrepancies in relationto the delivery documents.

5. StorageIf the IED is to be stored before installation, this must be done in the originaltransport casing in a dry and dust free place. Observe the environmentalrequirements stated in the technical data.

Section 4Unpacking and checking the IED


Section 5 Installing the IED

About this chapterThis chapter describes how to install the IED.

5.1 OverviewThe mechanical and electrical environmental conditions at the installation site mustbe within the limits described in the IED technical data. Dusty, damp places, placessusceptible to rapid temperature variations, powerful vibrations and shocks, surgevoltages of high amplitude and fast rise time, strong induced magnetic fields or similarextreme conditions should be avoided.Sufficient space must be available in front of and at the rear of the IED to allow accessfor maintenance and future modifications. Flush mounted IEDs should be mountedso that IED modules can be added and replaced without excessive dismantling.

5.3 Mounting methods and details5.3.1 Mounting the IED

Most of the IED 670s can be rack, flush or wall mounted with the use of differentmounting kits, see figure10. An additional box of type RHGS can be mounted to oneside of a 1/2 or 3/4 IED.



The different mounting kits contain all parts needed including screws and assemblyinstructions. 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 flushmounting.

The mounting kits must be ordered separately when ordering an IED.They are available as options on the ordering sheet in Accessoriesfor IED 670, see section 0.

Generally, all the screws included in delivered mounting kits are of Torx type and ascrewdriver of the same type is needed (Tx10, Tx15, Tx20 and Tx25).

If other type of screws are to be used, be sure to use the dimensionsof the screws that are given in this guide.

5.3.2 Flush mounting5.3.2.1 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 cubiclepanel, 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 x19 and are also suitable for mounting of RHGS6, 6U 1/4 x 19 cases.

Flush mounting cannot be used for side-by-side mounted IEDs whenIP54 class must be fulfilled. Only IP20 class can be obtained whenmounting two cases side-by-side in one (1) cut-out.

To obtain IP54 class protection, an additional factory mounted sealingmust be ordered when ordering the IED.

5.3.6 Side-by-side flush mounting5.3.6.1 Overview

It is not recommended to flush mount side by side mounted cases if IP54 is required.If your application demands side-by-side flush mounting, the side-by-side mountingdetails kit and the 19 panel rack mounting kit must be used. The mounting kit hasto be ordered separately. The maximum size of the panel cut out is 19.

With side-by-side flush mounting installation, only IP class 20 isobtained. To reach IP class 54, it is recommended to mount the IEDsseparately. For cut out dimensions of separately mounted IEDs, seesection "Flush mounting".

When mounting the plates and the angles on the IED, be sure to usescrews that follows the recommended dimensions. Using screws withother dimensions than the original may damage the PCBs inside theIED.

Please contact factory for special add on plates for mounting FTswitches on the side (for 1/2 19" case) or bottom of the relay.

Number 2 shows the one-phase plate with setting resistor and metrosil. Number 3 shows the necessary connection for the metrosil. Shown connections

are applicable for both types of one-phase plate. Number 4 shows the positionof optional test switch for secondary injection into the high impedancedifferential relay.

Number 4 shows the position of optional test switch for secondary injection intothe high impedance differential relay.

Number 5 shows the necessary connection for setting resistor. Shownconnections are applicable for both types of one-phase plate.

Number 6 shows how to connect the REF high impedance scheme to one CTinput in IED 670.

Number 7 shows a TRM module where this current input is located. Note thatthe CT ratio for high impedance differential protection application must be setas one! Thus for main CTs with 1A secondary rating the following setting valuesshall be entered: CTprim=1A and CTsec=1A; while for main CTs with 5Asecondary rating the following setting values shall be entered: CTprim=5A andCTsec=5A. The parameter CTStarPoint shall be always left to the default valueToObject.

Number 8 shows a connection made in Signal Matrix Tool (i.e. SMT) whichconnects this current input to first input channel of the preprocessing functionblock (10). For high impedance differential protection preprocessing functionblock in 3ms task shall be used.

Number 9 shows the preprocessing block which has a task to digitally filter theconnected analogue inputs. Preprocessing block output AI1 shall be connected



to one instances of high impedance differential protection function block (e.g.HZD1 function block in the configuration tool).

5.4.2 Connecting to protective earthConnect the earthing screw (pos 1 in figure 30) on the rear of the IED unit to theclosest possible earthing point in the cubicle. Electrical codes and standards requirethat protective earth cables are green/yellow conductors with a cross section area ofat least 2.5 mm2 (AWG14). There are several protective earthing screws on an IED.The Power supply module (PSM), Transformer input modules (TRM) and theenclosure are all separately earthed, see figure 30 below.The cubicle must be properly connected to the station earthing system. Use aconductor with a core cross section area of at least 4 mm2 (AWG 12).

Use the main protective earth screw (1) for connection to the stationsearthing system. Earthing screws for PSM module (2) and TRMmodule (3) must be fully tightened to secure protective earthconnection of these modules.



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

5.4.7 Making the screen connectionWhen using screened cables always make sure screens are earthed and connectedaccording to applicable engineering methods. This may include checking forappropriate earthing points near the IED, for instance, in the cubicle and/or near thesource of measuring. Ensure that earth connections are made with short (max. 10 cm)conductors of an adequate cross section, at least 6 mm2 (AWG10) for single screenconnections.

Inner shielding of the cable shall be grounded at the externalequipment end only. At the Relay terminal end, the inner shield mustbe isolated from protective ground.

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



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".

5.6 Galvanic X.21 line data communication (X.21-LDCM)

5.6.1 Connecting Galvanic X.21 line data communication module(X.21 LDCM)The Galvanic X.21 line data communication module (X.21 LDCM, see figure 22) isthe hardware used for the transfer of binary and analog signal data between IEDs indifferent protection schemes via telecommunication equipment, for example leased



telephone lines. For location of X-21 LDCM module, refer to section "Rear sideconnectors".The galvanic X.21 line data communication module uses a ABB specific PC*MIPType II format.

Soft groundTo avoid ground loops when the grounds are connected, a soft ground connection forthe IO-ground can be used. This is handled in the ground selection connector.



Three different kinds of grounding principles can be set:1. No ground - leave the connector without any connection2. Direct ground - connect the ground pin directly to earth3. Soft ground - connect the two pins to each other

The distance between earth points should be < 1200 m (3000 ft), see figure 38 and39. Only the outer shielding is connected to the protective earth at the terminal. Theinner and outer shieldings are connected to the protective earth at the externalequipment. Use insulating tape for the inner shield to prevent contact with theprotective earth. Make sure that the terminals are properly earthed with as shortconnections as possible from the earth screw, for example to an earthed frame.The terminal and the external equipment should preferably be connected to the samebattery.
