7. IF THE INVERTER FUSE BLOWS
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:
1. Disconnect the device or equipment immediately.
2. Find the source of the problem and repair it.
3. Install a new fuse (15A). The fuse can be found on the end of the plug on the
inverter.
4. Do not tighten the fuse cap too tight; finger-tight is sufficient.
ATTENTION: Do not install a fuse higher than 15A, as this may damage
the inverter. Make sure to correct the cause of the blown fuse before using the
inverter again.
