4.3 DC Wiring Installation Procedure
Verify the Power ON/OFF Switch is in the OFF position before connecting inverter to the battery.
Route the negative DC cable to the battery. Verify cable polarity before proceeding. The fuse will be
blown and inverter may be damaged if the DC cables are reversed. Route the positive DC cable to
the fuse and then to the battery. Protect cables with loom and use grommets or other appropriate
means where cables may contact hard, sharp edges.
Connect Chassis Ground Bonding Lug to the vehicle chassis and/or earth ground using 12AWG or
larger copper wire. (The wire must be sized to safely carry DC current as needed to blow the DC fuse
located near the battery in the inverter’s positive DC input cable.)
