1. Be sure the ON/OFF switch on the inverter is
in the OFF position.
2. Connect the cables to the power input termi-
nals on the rear panel of the inverter. The red
terminals are positive(+) and the black termi-
nals are negative (-). Insert the bare ends of
the cables into the terminals and tighten the
screws to clamp the wires securely.
3. Connect the cable from the negative terminal
of the inverter to the negative terminal of the
battery. Make a secure connection.
4. Double check that the cable you just installed
connects the negative terminal of the invert-
er to the negative terminal of the battery.
Power connections to the inverter must be
positive to positive and negative to negative.
5. Connect the cable from the positive terminal
of the inverter to the positive terminal of the
battery’s main fuse, or to the battery selector
switch, if you are using one. Make a secure
connection.
You might observe a spark when you make this
connection since current can flow to charge
capacitors in the inverter.
Operation.
Turn the inverter On by using the ON/OFF switch
on the left side panel .
The inverter is now ready to deliver AC power to
your loads. If several loads are to be operated by
the inverter, turn them on separately, after the
inverter has been turned On. This will ensure that
the inverter does not have to deliver the starting
currents required for all the loads at once.

WARNING: Do not make this
connection in the presence of
flammable fumes. Explosion or
fire may result. Thoroughly
ventilate the battery compart-
ment before making this con-
nection.

CAUTION: Loosely tightened
connectors result in excessive
voltage drop and may cause
over heated wires and melted
insulation.
CAUTION: Reverse polarity
connections (positive to nega-
tive) will blow internal fuses in
the inverter and may perma-
nently damage the unit. Such
damage is not covered by the
warranty.
CAUTION: We recommend a
main fuse in the battery’s posi-
tive cable to protect against
DC wiring short circuits (exter-
nal to the inverter). The fuse
should be as close to the bat-
tery as possible. We recom-
mend a Buss Fuse ANL-250 or
equivalent. The specific fuse
ampere rating should be sized
to allow operation of all your
DC powered equipment.
