To connect your inverter
to the power source:
1. Push the inverter’s ON/OFF
switch to OFF.
2. If the power source is a DC
power supply, switch it off.
3. To use the cigarette
lighter plug wire:
Connect the wire to the
posts on the right side of
the inverter. Insert the plug
into the cigarette lighter
of your vehicle.
To use the direct-to-
battery wire:
a. Connect the black cable
to the black post marked (-)
on the back of the CPI 300.
Connect the other end to
the negative terminal on
the battery.
b. Connect the red cable to
the red post marked (+) on
the back of the CPI 300.
Connect the other end to
the positive terminal on
the battery.
4. Plug the power cord from
the test load into the
inverter’s AC receptacle.
5. Check to be sure all power
connections are secure.
A reverse polarity connection
(positive to negative) will blow
the fuse in the inverter and may
permanently damage the unit.
Testing
Turn on the inverter. It should
supply power to the load. If
the inverter does not appear
to work properly, refer to the
Troubleshooting Guide on
page 7.

The location where you install
your CPI 300 must be:
• dry–Do not install the unit
where water can drip or
splash on it.
• cool–Ambient air temperature
should be between 30˚ and
105˚ F (0˚ and 40˚ C). The
cooler the better.
• ventilated–Allow at least
1 inch (3 cm) of clearance
around the unit for proper
air flow. Make sure that
ventilation openings on the
ends of the unit are not
obstructed.
To prevent fire, do not cover
or obstruct ventilation
openings. Do not install the
unit in a zero-clearance
compartment. Overheating
may result.
The inverter must only be
connected to batteries with a
nominal output voltage of
12 volts. It will not work with
a 6 volt battery, and will be
damaged if it is connected
to a 16 volt battery.
Turning on Your
Power Inverter
Turn on your CPI 300 by
pushing the ON/OFF switch
to ON.
The unit is now ready to deliver
AC power to your loads. If
several loads are to be powered
by the inverter, turn them on
separately AFTER the inverter
has been turned on. This will
ensure that the inverter will
not have to deliver the start-up
currents required for all loads
at once.
