RECHARGEABLE APPLIANCES

Certain rechargers for small nickel cadmium batteries can be damaged if connected to the CPI 150 BK. 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.

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 comes with a 24 inch cable and detachable cigarette lighter plug that converts to an airplane 12 volt female connector.

Do not connect to the power

source if flammable fumes are present. Explosion or fire may result.

QUICK CHECKOUT

To connect your inverter to the power source:

1. If the power source is a DC

power supply, switch it off.

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.

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.

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.

To prevent fire, do not cover or obstruct ventilation openings.

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.
