CAUTION The PDU is very heavy and may present a crush hazard if proper precaution and tools are
not used.
If site specifications require seismic mounting, use 5/8 in. (15mm) bolts, and the seismic brackets
and anchors that shipped with the NGPDU. Refer to Figure 1-79 for mounting hole locations, and
mount the PDU so it can be easily removed for service.
