2.2.3 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 to the inverter’s 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.
Refer to Figures 2-5 and 2-6 for the correct way to connect the DC cables and to stack the hardware.
Tighten the DC cable connections from 10 to 12 ft lbf (13.6 to 16.3 Nm).
CAUTION:
The DC terminal bolt and nut are made of stainless steel, which has a high
likelihood of seizure. To help prevent the bolt and nut from seizing—causing the bolt to
strip or snap/break-off—the use of an anti-seize lubricant is highly recommended.
Info:
If an antioxidant grease or spray is used, apply it after all the connections have
been made and are properly tighten.
Info:
A 1/2-inch wrench or socket is used to tighten the 5/16 SAE Flange or Kep nuts.
