RECHARGEABLE APPLIANCES
1
CAUTION
Certain rechargers for small
nickel cadmium batteries can
be damaged if connected to
the CPI 150 BK/WH. Two types
of equipment are particularly
prone to this problem:
1. Small battery operated
appliances that can be
plugged directly into
an AC receptacle for
recharging, including
flashlights, razors, and
night lights.
2. Certain battery chargers for
battery packs used in hand
power tools, specifically
those that have a
WARNING label stating
that dangerous voltages
are present at the battery
terminals.
1
Problems do not occur with
the vast majority of battery
operated tools, most of which
use a separate charger or
transformer that plugs into
an AC receptacle and
produces a low voltage
output. If the label on your
tool’s AC adapter or charger
states that is produces a low
voltage AC or DC output
(less than 30 volts) you
can safely power the charger
with your CPI 150.
In order to check the
performance of your
CPI 150 before using it,
please have the following
on hand:
1. A 12 volt DC power source
(such as a vehicle battery)
2. A test load such as a lamp
or other small appliance
that can be plugged into
the AC receptacle on the
inverter.
Power Source
You will need an 11 to
15 volt DC power source
capable of supplying enough
current to run the test load. As
a rough guide, divide the
wattage of the test load by 10
to get the current (in amperes)
that the power source must
supply. A fully charged
standard automotive battery
will work fine.

Connecting to the
Power Source
Your CPI 150 BK/WH comes
with a 24 inch cable and
detachable cigarette lighter
plug that converts to an
airplane 12 volt female
connector.
WARNING
Do not connect to the power
source if flammable fumes
are present. Explosion or
fire may result.

To connect your inverter
to the power source:
1. If the power source is a DC
power supply, switch it off.
Power Cord
2. Connect power cord to
the inverter.
3. Insert the cigarette lighter
plug into your vehicle’s
cigarette lighter.
4. For airline application, remove
lighter plug from cable.

Airplane Plug
Note: Some airplanes are
equipped with cigarette
lighter type socket.
5. Status LED on top of unit
will illuminate indicating
“on” status.
6. Plug the power cord from
the test load into the
inverter’s AC receptacle.
Testing
The inverter will come on
automatically. It should supply
power to the load. If the
inverter does not appear to
work properly, refer to the
Troubleshooting Guide on
page 7.
5V USB Outlet
The location where you should
use your CPI 150 must be:
dry–Do not use 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.
CAUTION
To prevent fire, do not cover
or obstruct ventilation
openings.
OPERATION
3
CAUTION
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.

Powering Up
To apply power to the CPI 150,
simply plug in to 12 Volt DC
source (cigarette lighter or
airplane power source).

Power/Fault Indicator
The "fault" indicator of your
CPI 150 will light whenever
the unit detects excessively
high or low input voltage, or
begins to overheat.

CAUTION NOTE: Make sure
you unplug inverter from
power source before you
leave your vehicle.
