4. Using one (1) 120 mm2 [#4/0] cable, connect the appropriate (top or bottom) BAT 2-
terminal in Terminal Block #2 to the BAT 2- terminal in Battery Breaker #2.
At Terminal Block #2: If using top cable entry, connect to top terminal (as shown) of the BAT
2- segment on right. Otherwise, connect to bottom terminal. Secure lug to stud with preset
washer and nut. To relieve strain, zip tie cable to the shelf directly above the terminal block.
At Battery Breaker #2: Refer to the battery breaker’s wiring diagram for the proper BAT 2- lug
landing on the other end of this cable.
Connecting terminal blocks to batteries
To minimize risk, connections between terminal blocks and batteries should be made FROM the
terminal blocks TO the batteries. 120 mm2 [#4/0] cable is supplied for all connections specified in
this section. Each terminal block assembly contains preset hardware for securing cable lugs.

Warning
Review “Safety” on page 1 for safety warnings and caution notices. Take heed of
all safety information before proceeding with battery connections. Failure to
comply could result in serious injury or death!
Note
Prior to making connections, use a voltmeter to measure collective voltage of the
BAT 1 (#1-32) and BAT 2 (#33-64) strings. Readings should approximate the
number of batteries in each string times 12V (or about 386V per string).
