Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Caution In a system with dual power supplies, connect each power supply to a separate input line. In case of a
line failure, the second source will most likely still be available.
Step 4 Verify that all connections to the DC PEM are secure.
Step 5 Remove the tape from the circuit breaker switch handle, and restore power by moving the circuit breaker
switch handle to the On (|) position.
