Centralized Architecture
Introduction
This section covers the field assembly for Centralized Architecture
DC power connections to central bus bar
Refer to Figure 6 - 1 for this procedure
Step
1
Install optional plates if more than 8 connections are needed. (See Figure 6 - 1.)
Run and connect new wires from positive and negative bus bars in each cabinet to charge and charge return
centralized bus bars located outside the equipment.
