2.4.3 DC Cable Connections
Do not put anything between the DC cable ring lug and the battery terminal post or the fl at metal
part of the inverter's DC terminal. When connecting the DC cable to the battery or inverter DC
terminals, the cable should be placed directly against the inverter or battery terminals. Incorrectly
installed hardware causes a high resistance connection, which could lead to poor inverter/charger
performance and may melt the cable and terminal connections.
Follow the examples in Figures 2-5 and 2-6 to connect the DC cables and stack the hardware
correctly. Tighten the terminal connections from 10 to 12 ft lbf (13.6 to 16.3 N-m).
CAUTION: The DC terminal and Kep nuts are made of stainless steel, which has a high
likelihood of seizure. To help prevent the bolt and nut from seizing — causing the bolts
to strip or snap/break-off — the use of anti-seize lubricant is highly recommended.
Info: If antioxidant grease or spray is used, apply it after all the connections have been
made and are properly tightened.
Info: A 1/2-inch wrench or socket is used to tighten the 5/16 SAE Kep nuts.
