DC Hardware Connections

Do not put anything between the DC cable lug and the DC terminals (i.e., on the Inverter DC
Disconnect, DC shunt busbars, batteries, or inverter terminals). Ensure the hardware used to hold
these connections is stacked correctly. Incorrectly installed hardware causes a high resistance
connection which could lead to poor inverter performance, and may melt the cable and terminal
connections. Follow Figure 3-20 to connect the DC cables and stack the hardware correctly.

Info:

After making the battery connections

and ensuring they are properly torqued,

cover the outside of the connection with petroleum jelly or an

antioxidant grease/spray.

Do not put jelly/anti-corrosion grease between the terminal and the battery cable.
