WARNING
Before replacing a blown fuse, it is necessary to remove the
cause of the blown fuse. For this reason, only the personnel
who have a working knowledge of maintenance and safety
are allowed to carry out this work. When replacing a fuse
with the cabinet open, be careful not to touch the
high–voltage circuit section (marked and shielded with
a shock hazard prevention cover). If you touch the
high–voltage circuit section when it is uncovered, you will
get an electric shock.
This section describes the replacement of the Power Mate controller fuse.
The controller contains a +24 V power input fuse, F1. If LED EN does not light
when +24 V power is supplied, fuse F1 may have blown. In such a case, remove
the fuse from its socket, then check its continuity using a multimeter (or visually
check whether it has blown). If the fuse has blown, investigate the cause, take
appropriate action, then replace the fuse. The capacity, part number, and
location of the fuse are as follows:
