Figure 13: Example of label to check PWR-XXXX part number
If you cannot read the base part number, ensure that the pull handles are both in a horizontal orientation
and that the sheet metal on the power cord face for each supply has the same perforation shapes.
When you add or replace a power supply unit in your system, be sure to verify the supply's features and
that the PWR-XXXX part numbers match to ensure that you have the correct supply.

multiple connections to the AC MAINS SUPPLY:
• The building installation shall provide a means for connection to protective earth; and
• The equipment is to be connected to that means; and
