Appendix C: Employing Sidecars

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 mm2 [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.

Be certain battery breakers are in the open (or OFF) position before making connections to them.

Electrical

Hazard

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.

Note

1.Using three (3) 253 mm2 [500 MCM] cables, connect the BAT 2- horizontal bar in the Sidecar to the specified BAT 2- bus in Battery Breaker #2.

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.
