6.5 Battery Connections
Battery cables should be sized for a 0.25 V drop from battery to the power system at full load including antici-
pated growth. The cables should also meet ampacity requirements.
6.5.1 Battery Return Connections
Procedure:
1. Connect the battery return cables to an external battery return bus bar, if installed, (Figure 26) or to the return
bus bar termination on the bay:

• 24 sets of 1/2" holes on 1¾" centers
• 24 sets of 3/8" holes on 1" centers
• 72 sets of 1/4" holes on 3/8" centers • 6 sets of 1/2" on 1 3/4" centers and/or
3/8" on 1" centers (12 if connected to both
sides of the bar)

6.5.2 Hot Voltage Battery Cables
CAUTION!
Do NOT make final connection to battery live. Insulate and leave disconnected or re-
move the battery fuses. Switch battery contactors off (if used).
1. Connect "hot" primary voltage cables directly to the primary "hot" voltage bus bar (Figure 27).
2. For the dual voltage option, connect "hot" secondary voltage cables directly to the secondary "hot" voltage
bus bar (Figure 27).
See Table F
on page 38 for
recommended
torque values.
