4. The case temperature becomes hot (exceeds 145°F). The Green and Red

rated output.

To reset after shutdown occurs:
1. Disconnect the converter from the 12V power source.
2. Check the source of the problem and correct.
3. Reconnect the converter to the 12V power source.

10. IF A CONVERTER FUSE BLOWS

Your power converter is fitted with two 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 a 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 (25A). The fuse can be found on the back of the converter.
IMPORTANT: Do not install a fuse with a higher amp rating than the original fuse, as
this may damage the converter and any product you use with the converter. Make
sure to correct the cause of the blown fuse before using the converter again.
