DC Cable Connections

When connecting the DC cable to the battery or to the inverter's DC
terminals, the hardware should be installed in the correct order to
prevent high resistance connections from heating up and possibly
causing the connections to melt. Follow Figures 11 and 12 to stack
the hardware correctly. Tighten the terminal connections from 10 to
12 foot-pounds.
CAUTION: Don't put anything between the DC cable ring
lug and the battery terminal post or the inverter's DC
terminal. If antioxidant grease or spray is used, apply it
after all the connections have been made and are properly
tightened.
CAUTION: Overtightening or misthreading nuts on the DC
terminals will cause the bolts to strip and snap/break-off.

CAUTION: The inverter is NOT reverse polarity protected
(negative and positive connected backwards). You must
verify the correct voltage polarity BEFORE connecting the
DC wires or damage may occur.
Crimped and sealed copper ring terminal lugs with a 5/16" hole should
be used to connect the DC wires to the inverter's DC terminals.
