Rechargeable Power Supply Owner's Manual

OPERATING TIPS

The

Power Force 50™

should only be operated in locations that meet the

following criteria:

DRY - Do not allow water or other liquids to come into contact with the inverter.

COOL - Ambient air temperature should be between -20°C and 40°C - ideally

between 15°C and 25°C (60 - 80°F). Do not place the inverter on or near a

heating vent or any piece of equipment which is generating heat above room

temperature. Keep the inverter away from direct sunlight, if at all possible.

VENTILATED - Keep the area surrounding the

Power Force 50™

clear to ensure

free air circulation around the unit. Do not place items on or over the inverter

during operation. The unit will shut down if the internal temperature exceeds 90°C.

Restart the unit once it cools down sufficiently.

SAFE - Do not use the

Power Force 50™

near flammable materials or in any

locations that may accumulate flammable fumes or gases.

Rated Versus Actual Current Draw of Equipment

Most electrical tools, appliances, electronic devices and audio/visual equipment

have labels that indicate the power consumption in amps or watts. Be sure that the

power consumption of the item to be operated is below 50 watts. If the power

consumption is rated in amps, simply multiply by the AC volts (110) to determine

the wattage.

Resistive loads are the easiest for the

Power Force 50™

to run; however, it will not

run larger resistive loads (such as electric stoves and heaters) which require far more

wattage than the

Power Force 50™

can deliver on a continuous basis. Inductive

loads (such as TVs and stereos) require more current to operate than do resistive

loads of the same wattage rating. Induction motors, as well as some TVs, may

require 2 to 6 times their wattage rating to start up. The most demanding in this

category are those that start under load, such as compressors and pumps. Testing

is the only definitive way to determine whether a specific load can be started and

how long it can run. For safety reasons, the unit will simply shut down if it is

overloaded. To restart the unit after a shutdown due to overloading, momentarily

turn off the power to the unit.

Note: The Power Force 50™ will not operate appliances and equipment that

generate heat, such as hair dryers, microwave ovens, and toasters.
