Protection relay's physical connections

Inputs

Energizing inputs

Differential currents

The protection relay can also be used in single or two-phase
applications by leaving one or two energizing inputs unoccupied.
However, at least terminals X120:7-8 must be connected.

Auxiliary supply voltage input

The auxiliary voltage of the protection relay is connected to terminals X100:1-2. At
DC supply, the positive lead is connected to terminal X100:1. The permitted auxiliary
voltage range (AC/DC or DC) is marked on the top of the LHMI of the protection
relay.
