50 Battery Rack Assembly and Installation Manual
Connecting sidecars to battery breakers
To minimize risk, sidecar-to-battery breaker connections are made prior to battery-to-terminal block
connections. TOP entry of 253 mm
2
[500 MCM] cable (not supplied) is recommended for all
connections specified in this section. To avoid cable congestion, the sidecar connections are made
from back-to-front in the enclosure.
1. Using three (3) 253 mm
2
[500 MCM] cables, connect the BAT 2- horizontal bar in the
Sidecar to the specified BAT 2- bus in Battery Breaker #2.
At Battery Breaker #2: Refer to the battery breaker’s wiring diagram for the proper BAT 2- lug
landings on the other end of these three (3) cables.
Electrical
Hazard
Be certain battery breakers are in the open (or OFF) position before making
connections to them.
Note
All external cable must comply with European and local electrical code. If using
conduit, BAT 1 (+ and -) and BAT 2 (+ and -) cables must be run separately.
At the Sidecar:
a. Make connections to the three (3) two-hole
landings nearest the RIGHT side of the
BAT 2- horizontal bar (refer to right
graphic). If using top cable entry, connect
with lugs pointing down. Otherwise,
connect with lugs pointing up. Secure the
three (3) lugs to their landings with six (6)
M12 [1/2”] bolts, washers, lock washers,
and hex nuts. Hardware not supplied.
b. If using top cable entry, reduce strain by zip
tying cables to supports at top of frame
(refer to below graphic). Zips not supplied.
