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.
