4.5 Fuses
There are four (4) fuses adjacent to the UPS CONTROL switch inside the
front door. If one of these fuses is blown, the control logic will not become energized
at startup. Once the UPS is started, it will operate even though one or more of the
fuses is blown.
In case a fuse blows, replace it with a fuse of the same make and size.
These are the only fuses available to the user unless he or she has had
authorized factory training.
