POWER AND GROUNDING
Figure 15 depicts a typical power and grounding layout for colocated PPN and EPN cabinets. A
ground wire from the ground block on the EPN cabinet connects to the single-point ground block
on the PPN cabinet. A 6-AWG ground wire connects the single-point ground block on the PPN
cabinet to an approved ground. (Also see ‘‘Grounding,’’ later in this section).
Note that the AC powering for a multi-carrier cabinet is as shown in Figure 15 for the PPN
cabinet.
