Removing a DC-Input Power Supply
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
To remove a DC-input power supply, follow these steps:
Step 1
Turn off the in-line power switch on the DC-input power supply front panel. (This step applies to the
single input power supply only, PWR-C45-1400DC-P; the triple-input power supply,
PWR-C45-1400DC, does not have this switch.)
Step 2
Verify that power is off to the DC circuit on the power supply that you are removing. As an added
precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or
place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration
while you are working on the circuit.
Step 3
Loosen the screw on the terminal block cover, remove the cover from the terminal block, and set it aside
(see
Figure 4-9
or
Figure 4-10
).
Note
The triple-input power supply has two screws securing the terminal block cover.
