Connecting Loads
Cable Routing Strategy
As with any power system, cabinet positioning with respect to cable racks, batteries, and the AC ser-
vice is very important in order to ensure easy installation, proper maintenance, and graceful growth of
the system in the future.
Each cabinet is arranged to separate ac leads from dc leads to minimize electrical noise transmitted
to the load. Run ac cable in an ac conduit mounted above the front of the cabinet. Route dc leads
along a cable rack above the back of the cabinet. Review Figure 5-7 for various cable rack arrangements.

ED83143-31 Groups 1 and 5 may also be equipped with a Capacitor Charge Unit (refer to Figure 8-1 to
mount this unit on the panel). The Group 5 has 5 circuit breaker positions. One position is not availa-
ble if the capacitor charge unit is mounted.
To use the Capacitor Charge Unit, follow the instructions silk-screened on the unit.
