2.4.3 DC Cable Connections
Do not put anything between the battery cable ring lug and the battery post or the fl at metal part
of the inverter's DC terminal. When connecting the battery cable to the battery post or inverter
DC terminal, the cable should be placed directly against the inverter terminal or battery post.
Incorrectly installed hardware causes a high resistance connection which could lead to poor inverter/
charger performance, and may melt the cable and terminal connections.
Refer to Figures 2-5 and 2-6 to connect the DC cables and to 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 Flange/Kep nuts are made of stainless steel which have
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 Flange/Kep nuts.
