LED INDIcATOR AND ShUTDOWN PROTEcTION 6.
The LED glows GREEN automatically when plugged into a 12-volt DC source and
will not glow under the following conditions:
When the power input from the vehicle’s battery drops to approximately 1.
10.5-volts, low battery shutdown occurs and inverter shuts off. Solution:
Recharge or Replace the battery.
When the power input from the vehicle’s battery exceeds 15.5-volts, high
2.
voltage protection occurs. Solution: Reduce the voltage range to between
11-volts and 15-volts.
The continuous load demand from the equipment or device being operated
3.
exceeds the continuous load rating of the inverter being used. Solution:
Use a higher capacity inverter or lower rated device.
The case temperature becomes hot (exceeds 145°F). Solution: Allow the
4.
inverter to cool. Do not block the cooling slots or air flow over and through
the inverter. Reduce the load on the inverter to the continuous rated output.
RESET: To reset after shutdown occurs, remove the 12-volt plug from the accessory
outlet. Check the source of the problem and correct. Reinsert the 12-volt plug into
the accessory outlet.
If ThE INvERTER fUSE BLOWS 7.
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:
Disconnect the device or equipment immediately. 1.
Find the source of the problem, and repair it. 2.
Install a new 15-amp fuse. The fuse can be found on the end of the plug on 3.
the inverter.
Do not tighten the fuse cap too tight; finger tight is sufficient.
4.
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.
