5.4 Connecting analog signals

A connection diagram is needed to connect the analog signals.

• Use the compression type for CT/VT terminals.The wires for the analog signals can be connected to the CT/VT terminals beforethe connector is connected to the protection relay. The connector features anautomatic short circuit mechanism for the current terminals. Therefore, detachingthe connector from the unit does not open the secondary circuit of the CT whichotherwise could cause dangerously high voltages.To avoid a mismatch between CT and VT connections, the connectors are colorcoded. The light gray pairs with short circuit facility are intended for CTs whilethe dark gray pairs without short circuit facility are for VTs. The counterpartconnectors on the module have the same color coding.

1. Energize the power supply of the protection relay and the optional LHMI. Thiscan be done in a number of ways, from energizing a whole cubicle to energizinga single protection relay.The following sequence is expected when the protection relay is energized:• The green Ready LED starts flashing instantly on the power supply

module of the protection relay.• Within 90 seconds both the green Ready LED of the power supply module

and the Home button on the LHMI show a steady light which indicates asuccessful start-up.

The start-up time depends on the size of the applicationconfiguration. Application configurations with lessfunctionality have shorter start-up times.

2. Check the self-supervision function via the HMI path Monitoring/IED statusto verify that the protection relay operates properly.

If the green Ready LED of the power supply module and theHome button on the LHMI continue to flash after the start-up,the protection relay has detected an internal error. Navigate toMonitoring/IED status to investigate the error description.
