Figure 9, DC Cable to Battery Terminals

DC Cable Connections

When connecting the DC cable to the battery or inverter DC terminals,

the hardware should be installed in the correct order to prevent high

resistance connections which will heat up and could cause the connec-

tions to melt. Follow Figures 9 and 10 to stack the hardware correctly.

Tighten the terminal connections from 10 to 12 foot-pounds.

CAUTION:

Do not put anything between the DC cable ring

lug and the battery terminal post or 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.
