1050 (example of total wattage) ÷ 120 (AC volts) = 8.75 amps
200 (amp-hour rating of 12V DC battery) ÷ 10 (always use 10) = 20 amp-hours @ 120 volts AC
20 (amp-hours @ 120 volts AC) ÷ 8.75 (amps) = 2.3 hours of operating time
To increase the operating time, the amp-hour rating must be increased. Either choose a battery with a
higher amp-hour rating, or connect multiple batteries together in parallel. If the 12-volt DC battery has
a rating of 200 amp-hours, connecting two 12-volt DC batteries, each having a 200 amp-hour rating
in a parallel arrangement, would increase the amp-hour rating to 400 amp-hours, doubling the time of
operation.
Use conservative estimates when selecting a battery. The number of amp-hours you expect to use
should be 50% of the battery’s rated amp-hours.
There is no accurate conversion formula for converting CCA (cold cranking amps)
into battery amp-hours. There are too many variations between battery manufacturers to
have a standard formula. To determine the amp-hours for your battery, contact the battery
manufacturer.
P
ositioning of Power Inverter
When using the remote outlet with the Inverter, make sure the Inverter is not
mounted more than 10 ft (3 m) away from where the remote outlet will be mounted. The cords
for the remote outlet will not reach the Inverter if it is more than 10 ft (3 m) away.
Position the Power Inverter on a reasonably flat surface. DO NOT place on or under the vehicle
seats. Allow at least 3 in. (76 mm) of clearance around the Inverter to allow for airflow. Always use the
Inverter where there is adequate ventilation. Do not block ventilation slots or the cooling fan.
Install the Inverter as close to the DC power source as possible. It is more efficient to use longer AC
wiring than DC wiring.
If desired, the Power Inverter can be solidly mounted to a base using the mounting brackets.
If installed in a vehicle, it is recommended that the Inverter be shock-mounted using
a rubber isolation pad between the Inverter and the base.
The Inverter can be mounted on a vertical surface, on a horizontal surface or under a horizontal
surface. Install the Inverter so that the receptacles and the ON/OFF switch are accessible.
Do not install the Inverter on a vertical surface where the cooling fan is facing up or
down.
FIRE HAZARDS
• Do not place the Inverter near flammable materials or in any location that may accumulate
flammable fumes or gases such as the battery compartment of your vehicle or engine
compartment of your boat.
• Do not expose the Inverter to extreme heat or flames. The surrounding air temperature
should be between 14° and 104°F (-10° and 40°C). Do not place the Inverter on or near a
heating vent or any equipment which is generating heat above room temperature. Do not
place the Inverter in direct sunlight.
ELECTROCUTION HAZARD
Do not operate the Inverter if it is wet. Do not allow water, moisture or other liquids to come in
contact with the Inverter, the device being operated or the power source.
Marine Installation
Marine installations are subject to additional vibration and stress on the cables.
Marine installations require tight, water-resistant electrical connections with slack in both the
cables and appliance wiring. Use the appropriate cable insulation for the environment.
Install the Power Inverter away from moisture and water. Install the Inverter above the waterline, as
high as possible. The Inverter must not be installed below or near the waterline.
The Inverter’s DC input must be connected to approved marine wiring using non-corrosive marine
fasteners and fittings.
Connecting to P
ower Source
FIRE HAZARD
Do not connect the Inverter to RV or household AC distribution wiring, to an AC load circuit
or where the neutral conductor is connected to the negative terminal of a DC power source.
Connecting to these circuits could cause damage to the Inverter and/or create a spark.
Do not use with positive gr
ound electrical systems. Connecting the Inverter to a
positive ground electrical system will damage the Inverter. Only use the Power Inverter on
negative ground electrical systems. If in doubt, check with your vehicle dealer or consult the
vehicle’s owner’s manual.
