Replacing Fuses (DC)
If a fuse is tripped, there is no current flow on the DC side.
A total of 6 vehicle fuses (40 A) are located on the rear of the LPS. The upper
3 fuses protect the DC output, the lower 3 fuses the DC input.
To replace the fuses, perform the following steps:
1. Switch off the LPS.
2. Remove the damaged plug-in fuses on the back of the LPS.
3. Insert fuses of the same type and rating into the fuse device.
The fuses have been replaced.
Replacing Fuses (AC)
If a fuse has been tripped, there is no current flow on the AC side. Check that
the fuse toggle switches are facing upwards.
The fuses (AC) are located in the fuse box on the front of the LPS. Open the
fuse box and push the toggle switch upwards if necessary.
