IRF
The IRF contact functions as a change-over output contact for the self-supervision
system of the IED. Under normal operating conditions, the IED is energized and one of
the two contacts is closed. When a fault is detected by the self-supervision system or
the auxiliary voltage is disconnected, the closed contact drops off and the other contact
closes.
Each signal connector terminal is connected with one 14 or 16 Gauge wire.

Communication connections

The IED's LHMI is provided with an RJ-45 connector. The connector is intended for
configuration and setting purposes.
Rear communication via the X1/LAN1 connector uses a communication module with
the optical LC Ethernet connection.
The HMI connector X0 is used for connecting an external HMI to the IED. The X0/
HMI connector must not be used for any other purpose.
Rear communication via the X8/EIA-485/IRIG-B connector uses a communication
module with the galvanic EIA-485 serial connection.
Ethernet RJ-45 front connection
The IED's LHMI is provided with an RJ-45 connector designed for point-to-point use.
The connector is intended for configuration and setting purposes. The interface on the
