BEFORE USING YOUR POWER INVERTER

When you turn on a device or a tool that runs on a motor, the device basically goes through two stages:

1.

Start Up – Requiring an initial surge of power (commonly

2.

known as the “starting or peak load”).

Continuous Operation – Power consumption drops (commonly known as the “continuous load”).

The wattage (WATTS) or amperes (AMPS) can normally be found stamped or printed on most devices and equipment, or in the user’s manual. Otherwise, contact the manufacturer to find out

• 2 •

whether the device you want to use is compatible with a modified sine wave.

To calculate the wattage: Wattage = AMPS x 120 (AC Voltage).

To calculate the starting load: Starting Load = 2 x WATTS. In general, the start up load of the device or power tool determines whether your inverter has the capability to power it.

To calculate the continuous load: Continuous Load = AMPS x 120

(AC Voltage).

Always run a test to establish whether the inverter will operate a particular piece of equipment or device. In the event of a power overload, the inverter is designed to automatically shut down.

This safety feature prevents damaging the inverter while testing devices and equipment within the wattage range of the inverter.

When using the vehicle’s 12 volt accessory port, this inverter is designed to supply 60 to 70 watts when the vehicle is not running. With the vehicle’s engine running, it can supply up to

100 watts. To use the full output, you must connect the inverter directly to your battery.

NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles. Some vehicles may allow the full output. If the fuse blows when you switch on the device you are trying to use, you have to either use a smaller device or you must connect the inverter directly to the battery.

6.

press the Display button.

To disconnect, reverse the above procedure.

NOTE: If more than one device is to be powered, start one device at a time to avoid a power surge and overloading the inverter.

The surge load of each device should not exceed the inverters

Continuous Operation wattage rate.

If there is a short circuit or power surge in the device,  will display and the alarm will sound. Press the ON/

OFF switch to turn off the alarm. If the  displays after several attempts, there is a short circuit or the device requires more

“starting” or “peak” load than the inverter is capable of providing.

NOTE: After two  events the inverter will go into a mandatory 10 second cool down period before it will turn on again.

If you are using the power inverter to operate a battery charger, monitor the temperature of the battery charger for about 10 minutes. If the battery charger becomes abnormally warm, disconnect it from the inverter immediately.

NOTE: You can use an extension cord from the inverter to the device without significantly decreasing the power being generated by the inverter. For best operating results, the extension cord should be no longer than 50 feet.

Using the Inverter to Operate a TV or Audio Device:

The inverter is shielded and filtered to minimize signal interference. Despite this, some interference may occur with your television picture, especially with weak signals. Below are some suggestions to try and improve reception.

1.

Make sure the television antenna produces a clear signal

2.

under normal operating conditions (i.e. at home plugged into a standard 120-volt AC wall outlet). Also, ensure that the antenna cable is adequately shielded and of good quality.

Try altering the position of the inverter, antenna cables, and television power cord. Add an extension cord from the inverter to the TV so as to isolate its power cord and antenna cables from the 12-volt power source.

Try coiling the television power cord and the input cables

3.

4.

running from the 12-volt power source to the inverter.

Affix one or several “Ferrite Data Line Filters” to the television power cord. Ferrite Data Line Filters can be purchased at most electronic supply stores.

NOTE: You may hear a “buzzing” sound being emitted from inexpensive sound systems when operated with the inverter. This is due to ineffective filters in the sound system’s power supply.

Unfortunately, this problem can only be resolved by purchasing a sound system with a higher quality power supply or higher quality filter.

POWER SOURCE

Your average automobile or marine battery at full charge will provide an ample power supply to the inverter for approximately 3 hours when the engine is off. The actual length of time the inverter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the inverter.

If you decide to use the inverter while the engine is off, we recommend you turn OFF the device plugged into the inverter before starting the engine. To maintain battery power, start the engine every 2 to 3 hours and let it run for approximately 10 minutes to recharge the battery.

Although it is not necessary to disconnect the inverter when turning over the engine, it may briefly cease to operate as the battery voltage decreases. While the inverter draws very low

IF THE INVERTER FUSE BLOWS

Your power inverter is fitted with a fuse, which should not have to be replaced under normal operating conditions. A blown fuse is usually caused by reverse polarity or a short circuit within the device or equipment being operated.If the fuse does blow:

1. Disconnect the device or equipment immediately.

2. Find the source of the problem, and repair it.

3. Install a new fuse, 15-amp. The fuse can be found on the end of the plug on the inverter.

4. Do not tighten the fuse cap too tight; finger tight is sufficient.

• 7 •

8.

Do not install a fuse higher than 15-amp, as this may damage the inverter. Make sure to correct the cause of the blown fuse before using the inverter again.
