If The Converter's Fuse Blows; Troubleshooting - Schumacher SI1479 Manual Del Usuario

2. When the power input from the vehicle's battery exceeds 15 volts, high voltage
protection occurs. Solution: reduce the voltage range to between 12 and 14 volts.
3. The continuous load demand from the equipment or device being operated
exceeds the continuous load rating of the converter being used. Solution: use
a higher capacity converter or lower rated device.
4. The case temperature becomes hot (exceeds 145°F). Solution: allow the
converter to cool. Do not block the cooling slots or air flow over and through
the converter. Reduce the load on the converter to the continuous rated output.
RESET: To reset after shutdown occurs, remove the 12V plug from the accessory
outlet. Check the source of the problem and correct. Reinsert the 12V plug into the
accessory outlet.

7. IF THE CONVERTER'S FUSE BLOWS

Your power converter 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 25A fuse. The fuse can be found on the end of the plug on the
converter.
4. Do not over-tighten the fuse cap; finger-tight is sufficient.
ATTENTION: Do not install a fuse higher than 25A, as this may damage the converter.
Make sure to correct the cause of the blown fuse before using the converter again.
