Fusing Information
WARNING: To reduce the risk of fire, replace fuses only with the same type
and rating.
The DP564 uses a universal switching power supply that handles the full range of
nominal mains voltages between 90 and 264 VAC and any frequency between 50
and 60 Hz.
Main Fuse
The main fuse rating is:
T 1A L (1 amp, 250 V, 20 mm, time-lag, low breaking capacity) for all operating
voltages.
The power cord must be removed from the rear-panel connection to inspect or replace
the fuse.
To inspect or replace the main fuse:
1. Slide open the fuse compartment in the AC power input housing by placing
the tip of a small screwdriver in the notch.
2. Carefully pull out the fuse carrier.
3. Either replace the fuse with a new one, or check that the current fuse has the
correct rating.
4. Slide the fuse compartment back into place, then snap the fuse compartment
closed.
Internal Fuse
The switching power supply contains a separate fuse. Most fault conditions should be
protected by the main fuse.
If you find it necessary to replace the internal fuse, be certain to replace it with a fuse
of the same type and rating as printed on the switching power supply board.
