IMPORTANT:
Vehicle batteries are designed to
provide brief periods of very high current needed
for engine starting. They are not intended for
constant deep discharge. Regularly operating
the power inverter from a vehicle battery until
low-voltage shutdown occurs will shorten the life
of the battery.
• If an AC product rated higher than Watts men-
tioned in the product is plugged into the power
inverter, the inverter will shut down. The red fault
light comes on.
• If the power inverter exceeds a safe operating
temperature, due to insufficient ventilation or a
high-temperature environment, it automatically
shuts down. The red fault light comes on.
• Should a defective battery charging system cause
the battery voltage to rise to dangerously high
levels, the power inverter automatically shuts
down. The red fault light comes on.
CAUTION:
Although the power inverter incorpo-
rates protection against over-voltage, it may still be
damaged if the input voltage exceeds 16 V.
• In the event of an overload, low battery voltage
or overheating, the power inverter automatically
shuts down.
BATTERY OPERATING TIME
Operating time will vary depending on the charge
level of the battery, its capacity and the power level
drawin by the particular AC load. With a typical
vehicle battery and a 130 W load, an operating time
of 2 to 2,5 hours or more can be expected.
When using a vehicle battery as a power source, it
is strongly recommended to start the vehicle every
hour or two to recharge the battery before its
capacity drops too low.
The power inverter can operate while the engine is
running, but the normal voltage drop that occurs
during starting of the engine may trigger the
inverter’s low voltage shutdown feature.
INTERFERENCE WITH ELECTRONIC EQUIPMENT
Generally, most AC products operate with the
power inverter just as they would with household
AC power. Below is information concerning two
possible exceptions.
BUZZING SOUND IN AUDIO SYSTEMS AND RADIOS
Some inexpensive stereo systems and AM-FM radios
have inadequate internal power supply filtering
and “buzz” slightly when powered by the power
inverter. Generally, the only solution is an audio
product with a higher quality filter.
TELEVISION INTERFERENCE
With weak TV signals interference may be visible
in the form of lines scrolling across the screen. The
following should minimize or eliminate the problem:
- Increase the distance between the power inverter
and the TV, antenna and cables.
- Adjust the orientation of the power inverter,
television, antenna and cables.
- Maximize TV signal strength by using a better
antenna and use shielded antenna cable where
possible
