When installing the unit, the ground connection must always be made first and disconnected last.
Step 8 Secure the ground cable to the cable holder with the two cable-ties.
Step 9 Retrieve the cable holder covers from the plastic bag and attach to the front panel at the locations shown
in Figure 9-3.
Note If the cable holder illustrated as number 5 and 8 in Figure 9-3 does not hold the DC input cables snugly,
please use a long cable tie to secure the cable holders as illustrated in number 9.
Step 10 Secure the terminal block cover using four screws and the terminal block barriers with two screws each.
Step 11 Turn on the DC inputs and verify power supply operation by checking the power supply front panel
LEDs.
The power supply rear panel LEDs should be in the following states:
• INPUT OK LED is green
• FAN OK LED is green
• OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see Identifying Startup Problems, page 8-6
