Operation of the Inverter’s Automatic Shutdown Features
Over-voltage
- The Inverter automatically shuts down when the input voltage
from the vehicle or battery exceeds 15.6 Volts DC.
Low-voltage
- An audible alarm will sound and the Inverter will shut down
when the battery voltage reaches the lower voltage range of battery health:
11.3V. When the condition is corrected, the unit will restart.
Overload
- The Inverter automatically shuts down when the continuous AC
draw exceeds 150 Watts.
Short circuit
- The Inverter automatically shuts down when it detects a short
circuit or reverse polarity. This condition will usually result in the fuse being
blown. Immediately disconnect the shorted load and replace the fuse as
described in
Fuse Replacement
(see page 8).
Overheating
- The Inverter automatically shuts down when its internal temper-
ature rises above 140° F (60° C). Allow the unit to cool for at least 15 minutes
before restarting after a heat-related shutdown. Unplug unit while cooling.
Starting and Running the Vehicle’s Engine
• The Inverter may be used whether or not the vehicle’s engine is running.
However, the Inverter may momentarily stop operating while the engine is
starting since the battery voltage can drop substantially during cranking.
• The Inverter draws less than 0.3 Amps from the battery when it is not
supplying power to a load. Therefore, in most instances, the Inverter can
be left connected to the battery when not in use since it draws so little
current. However, if the vehicle is to remain unused for more than one
day, disconnect the Inverter from the battery.
• Depending on variables such as battery condition, device being operated,
even weather, an automotive battery can be discharged after 2 to 8 hours of
use. Users should either monitor voltage or start the vehicle every hour to
recharge the vehicle’s battery. This will guard against any unexpected shut-
down of the equipment and will ensure that there is always sufficient power
to start the vehicle.
• With the engine running the battery has much more capacity available and
at a higher voltage. If the Inverter is shutting down due to an excessive load
with the engine off, keeping the engine running may remedy the problem.—
