Connecting the differential relay
There is a potential free differential relay contact (semiconductor relay) at the
clamps K1 to K4; K1 and K3 are the common connectors of the relay. If a voltage
breakdown, a RJ45-port error or a fiber optic port error is detected, the differential
relay drops down (K1-K2 closed and K3-K4 opened).
Function of the contacts K1 – K2: Differential relay contact: closes in case of errors
Function of the contacts K3 – K4: Differential relay contact: opens in case of errors
The capacity of the differential relay contact is 25VDC (1A) or 60VDC ( 0,3A)
[Note] When wiring, please mind the appropriate cable cross-section of at
2
least 0,75mm
