Safety information

Strictly follow the company and international safety regulations.

Working in a high voltage environment requires serious approch to

aviod human injuries and damage to equipment

Do not touch any circuitry during operation. Potentially lethal

voltages and currents are present

Avoid to touching the circuitry when covers are removed. The IED

contains electirc circuits which can be damaged if exposed to static

electricity. Lethal high voltage circuits are also exposed when covers

are removed

Using the isolated test pins when measuring signals in open circuitry.Potentially lethal voltages and currents are present

Never connect or disconnect wire and/or connector to or from IED

during normal operation. Dangerous voltages and currents are

present. Operation may be interrupted and IED and measuring

circuitry may be damaged

Always connect the IED to protective earth regardless of the


5/221

operating conditions. Operating the IED without proper earthing may

damage both IED and measuring circuitry and may cause injuries in

case of an accident.

Do not disconnect the secondary connection of current transformer

without short-circuiting the transformers secondary winding.

Operating a current transformer with the secondary winding open will

cause a high voltage that may damage the transformer and may

cause injuries to humans.

Do not remove the screw from a powered IED or from an IED

connected to power circuitry. Potentially lethal voltages and currents

are present

Using the certified conductive bags to transport PCBs (modules).

Handling modules with a conductive wrist strap connected to

protective earth and on an antistatic surface. Electrostatic discharge

may cause damage to the module due to electronic circuits are

sensitive to this phenomenon

Do not connect live wires to the IED, internal circuitry may be

damaged

When replacing modules using a conductive wrist strap connected to

protective earth. Electrostatic discharge may damage the modules

and IED circuitry

When installing and commissioning, take care to avoid electricalshock if accessing wiring and connection IEDs

Changing the setting value group will inevitably change the IEDs

operation. Be careful and check regulations before making the

change

The Human Machine Interface (HMI) on the IED provides an ideal

mechanism for the day to day operation and even advanced use of the IED.

The keyboard, LCD and LEDs on the front of the IED are what constitute the

HMI. Troubleshooting, monitoring, setting and configuring are all possible via

this interface. Through the screens and menu elements available, as well as

the keypad, the user is able to navigate throughout the menu structure and

move from screen to screen.

The IED is unpacked and visually checked. The connection to the protection

system has to be checked in order to verify that the installation is successful.

The settings for each function must be calculated before the commissioning

task. The functions setting menu have been listed in detail so that the user

can find and change the required settings directly and correctly. For the

different application, the IED can be performed conveniently throughswitching the setting group.

For the functions included in the IED can be tested by users, the testing

procedure have been listed as reference to verify that protection function

operate correctly.

After the IED is in service, some checking items also need to be done for

maintenance in order to ensure that the IED is in good condition during

operation, some suggestions have been preset as reference and the user can

perform some other checking items according to the relevant regulations.

connected with the IED via this port to make setting, testing and cofiguration,

etc.

3.2 Connecting to protective earth

Connect the earthing screw on the rear panel to the nearest protective

earthing point in the cubicle. The protective earth cables should be green or

yellow conductors with cross-sectional area 2.5mm2according to electrical

regulations and electrical standards requirement.

The cubicle must be properly connected to station earthing system, using the

conductor with cross-sectional area of at least 4mm2.

3.3 Connecting the power supply module

The wiring from the cubicle terminal block to the IED terminals must be

connected in accordance with the established guidelines for this type of IED.

The wires from binary inputs and outputs and the auxiliary power supply must

be routed separated from the current transformer cables between the terminal

blocks of the cubicle and the IEDs connections.

3.4 Connecting to CT and VT circuits

CT and VT are connected to the analogue input module on the rear side of

the IED.

Using solid conductor with cross-sectional 2.5-6mm2(AWG14-10) or stranded

conductor with cross-sectional 2.5-4mm2(AWG14-12). The screws used for

fixation conductor should be tightened.

3.5 Connecting the binary inputs and outputs

Auxiliary power supply and binary input and output signals are connected

using female connectors. Signal wires are connected to a female connector,

which is then plugged into the corresponding male connector, located at the


39/221


29

rear of the IED.

Procedure:

1. Connect wire 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

0.2-1.5 mm2 (AWG 24-15). If two conductors are used in the same

terminal, the maximum permissible cross section area is 0.2-0.8 mm2

(AWG 24-18, each conductor corresponding to one cross section area).

If two conductors, each with area 1.5 mm2(AWG 15) need to be

connected to the same terminal, a ferrule must be used to combine the

two conductors, no soldering is needed.

Press the locking button by screwdriver to insert the wiring with ferrule

into the connector, move away the screwdriver after the ferrule has been

inserted into the connector completely to lock the wiring tightly. The follow

picture illustrates this process.

30

Figure 12 Connection illustration with inserting the connector

2. Plug the connector to the corresponding back-side mounted male

connector

3. Lock the connector by fastening the lock screws

3.6 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 earth points near the IED, for instance, in the cubicle

and/or near the source of measuring. Ensure that earth connections are

made with short conductors of an adequate cross section, at least 6 mm2(AWG10) for single screen connections.

3.7 RS485 and RS232 ports connection

3.7.1 RS485 port connection

The RS485 interface is capable of half-duplex service with the signals A/A'

and B/B' to transmit signals.
