The Guardian 5000 can be operated from a power source of 90 to 130 VAC or 200 to
250 VAC. Power connection is via the rear panel through a standard receptacle. Before
connecting the 3-wire power cord between the unit and AC power source make sure the
voltage selection switches on the rear panel (as indicated) and fuses are in accordance with
the power source being used. 7A, 250V, 5x20mm, for 90-130V source and 3.5A, 250V,
5x20mm, for 200-250V source. Always use an outlet which has a properly connected
protection ground.
To change the fuse proceed as follows:
WARNING
MAKE SURE THE UNIT HAS BEEN DISCONNECTED FROM ITS AC POWER
SOURCE FOR AT LEAST FIVE MINUTES BEFORE PROCEEDING.
Remove the fuse drawer, by inserting a flat head screwdriver behind the small tab located just
below the 3 prong receptacle, and force outward.
Once the fuse drawer has been removed from the instrument snap the fuse from the holder
and replace. Make sure the new fuse is of the proper rating. Note that the fuse drawer can
also be used to store a spare fuse.
Install the fuse drawer back in the inlet module (fuse down) by pushing in until it locks
securely in place.
