IF THE INVERTER FUSE BLOWS 10.
The power inverter is fitted with fuses, 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 fuses blow:
The fuse is not user replaceable; take the inverter to a qualified service person. (Call 1.
customer service at: 1-800-621-5485.)
