WARNING
The following instructions are for use by qualified personnel
only. To avoid electrical shock, do not perform any servicing
other than contained in the operating instructions unless you are
qualified to do so.
Line voltage is exposed when the top cover is removed from the
power supply, and is present on the fuseholder and power switch
even when the unit is turned off.
FUSE REPLACEMENT
If the fuse blows, the LED indicator will not light and the power
supply will not operate. The fuse should not normally open unless
a problem has developed in the unit. Try to determine and correct
the cause of the blown fuse, then replace only with a fuse of the
correct rating as listed in Table 1. The fuse is located on the rear
panel (see Fig. 2).
