7.5. Output relays
7.5.1. ARC-EM/2.0
Connect the circuit breaker’s trip circuits to the following terminals (a maximum of four sepa-
rate trip outputs in two separate groups):
TRIP1: X1-7, X1-8 (fast, group 1)
TRIP2: X1-9, X1-10 (fast/CBFP, group 1)
TRIP3: X1-11, X1-12 (fast, group 2)
TRIP4: X1-13, X1-14 (fast/CBFP, group 2)
Connect the self-supervision alarm output to an IF change-over contact, either terminals X1-
17, X1-18 (normally open) or X1-19, X1-20 (normally closed).
During normal system operation (no internal fault) and with the auxiliary power supply con-
nected, the terminal X1-17, X1-18 are closed and X1-19, X1-20 are open.
Connect the trip alarm output to the closing terminals X1-15, X1-16.
7.5.2. ARC-EP10/2.0, ARC-EL3/2.0 and ARC-EC1/2.0
Connect the circuit breaker’s trip circuit to the following terminals:
TRIP1: X2-15, X2-16 (fast)
The output trip relay of the arc I/O units (ARC-EP10/2.0 and ARC-EL3/2.0) operates during
faults in its own zone. In the current I/O unit (ARC-EC1/2.0), select the protection zone con-
trolling the I/O unit using the programming switches.
7.5.3. ARC-EP10-2/2.0
Connect each output relay to corresponding breaker.
Sensor channel 1 controls Trip output 1 (X2-15, X2-16)
Sensor channel 2 controls Trip output 2 (X2-11, X2-12)
Sensor channel 3 controls Trip output 3 (X2-8, X2-9)
