Wiring Steps
Disconnect the positive battery terminal before doing any
wiring to the inverter.
Using proper sized copper wire and proper terminations,
wire the inverter to the electrical system and fuse block.
See your local RV dealer or automotive shop for wire,
connectors, fuse block and other wiring parts. Tighten all
connections firmly, but do not over tighten. Remember to
recheck all connections every few months of operation.
Use ring type lugs for a ¼” post to attach to the wire.
Crimp the rings to the wire and slide the rings over the
binding post and tighten securely by hand.
WARNING: Do not operate the power inverter
without a fuse installed.
Double check all wiring for proper polarity.
Install the fuse and reconnect the wire to the battery. Note,
a slight spark and beep from the inverter is normal when
the unit is first connected to 12 volt power.
