Auxiliary supply voltage input

The auxiliary voltage of the IED is connected to terminals X420-1 and X420-2/3. The
terminals used depend on the power supply.
The permitted auxiliary voltage range of the IED is marked on top of the IED's LHMI.

Binary inputs
The binary inputs can be used, for example, to generate a blocking signal, to unlatch output
contacts, to trigger the digital fault recorder or for remote control of IED settings.
Each signal connector terminal is connected with one 14 or 16 Gauge wire.
