NOTICE

1.

It is crucial to connect the +24 VDC power supply to the correct terminal. Improper connection can destroy the

electronic protection functions of the circuit breaker. The trip unit imposes a load of 45 ma. 

2. The OPTIM 550 Ground Fault Trip and Ground Fault Alarm units have "NS and NS*" wires. The Non-Ground Fault

Optim 550 units have no wires.

3.

Customer wiring connections are made on the removable male plug of the terminal block. 

4. If the customer requires the interlock feature in their system then the removal of the jumper between

positions 2
