Step 7
Connect the DC-input wires to the power entry module terminal block. The proper wiring sequence is positive to positive
(red wire) and negative to negative (black wire).
Step 8
Replace the terminal covers as shown in the figure above.
This cover should always be in place when power is applied to the terminals.
Step 9
Set the DC disconnect switch in the circuit to ON.
In a system with multiple power supplies, connect each power supply to a separate DC power source. In the
event of a power source failure, if the second source is still available, it can maintain system operation.
Caution
Step 10
Verify power supply operation by checking the power supply LED on the front of the chassis.
See
