5.2.4 INSTALLATION IN EG4 BATTERY RACK
1. Insert the battery into the rack slot, beginning with the top slot and progressing downward. Slide
in until the battery is firmly seated in the rack.
2. Follow steps 1-3 in Connecting cables to the battery terminals and busbars from Section 3.2.3 -
General Installation.
Use the included 2 AWG power cable to connect each battery to the busbar.
3. DO NOT finger tighten the battery or
busbar terminal bolts. Both require a
specific torque [60 in. lbs. (7Nm)] to
ensure they do not loosen during
operation. Failure to properly tighten the
terminal bolts can result in serious
damage and will void the warranty.
4. Clearly identify the location of the
system’s positive and negative terminals
(red to the positive terminal and black to
the negative) to ensure no connection
errors. Then connect to the equipment or
switch terminals.
Grounding
You can attach a grounding wire from the
rack/cabinet to an equipment grounding
conductor, then terminate the EGC at a
grounding electrode.
For example, in this image, there are 6 EG4-LL
12V 400Ah batteries wired in parallel. This
battery bank still maintains the appropriate 12V
needed for a system. However, the Amp hour
rating of this bank has increased to 2400Ah. In
addition, the potential output amperage of the
rack increases. Size main battery cables
appropriately! Refer to an NEC approved
ampacity chart for specifications.
