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 0.5...2.5 mm
2
0.5...1.0 mm wires.

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
PC has to be configured in a way that it obtains the IP address automatically if the
DHCPServer is enabled in LHMI. There is a DHCP server inside IED for the front
interface only.
The events and setting values and all input data such as memorized values and
disturbance records can be read via the front communication port.
Only one of the possible clients can be used for parametrization at a time.
