Grounding Considerations
The ground terminal on the Power Supply module and the grounding lug on the rack
are not connected. Both points must be connected externally to earth ground and
checked with an ohmmeter before power is applied. Use a star washer (toothed lock
washer) to ensure effective grounding. Refer to figure 5.3 (four-slot rack) or figure 5.4
(eight-slot rack) for the location of the Power Supply module ground terminal and the
rack grounding lug.
!
ATTENTION: Ungrounded equipment presents a shock hazard. The
ground terminal on the power supply module and the grounding lug on
the rack are not connected together. Connect both points to an external
earth ground.
