Dc Cable Connections; Figure 2-6, Dc Cable To Battery Terminals - Magnum Energy MMS Series Owner's Manual

2.2.4 DC Cable Connections

When connecting the DC cable to the battery or to the inverter's DC
terminals, the hardware should be installed in the correct order to
prevent high resistance connections from heating up and possibly
causing the connections to melt. Stack the hardware per Figures
2-6 & 2-7. Tighten the terminal connections from 10 to 12 ft-lbs
(13.6 to 16.3 N m).
CAUTION: Do not put anything between the DC cable
ring lug and the battery terminal post or the 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.
