NOTES
Reverse polarity protection
If the battery is connected in reverse, the internal battery protection fuse may be ruptured and the unit should be re-
turned to the manufacturer for repair. If the fuse is good, the voltage measured as at step 3 above should be exactly the
same on both the load and battery outputs.
