Voltage Selection
To change selected voltage: remove the fuse
cartridge using a small blade screwdriver or similar
tool; select the desired voltage by matching the
arrow on the fuse cartridge to the arrow located on
the front of the unit (lower right corner); replace the
fuse cartridge making sure the voltage selection
arrow aligns with the arrow located on the front of
the unit.

Changing Fuses
Remove the fuse cartridge using a small blade screw-
driver or similar tool; for Metric fusing pull out the
sliding fuse covers located at the top of each fuse
compartment; insert desired fuses; push the sliding
fuse covers back in place and insert the fuse
cartridge back into the unit making sure the voltage
selection arrow aligns with the arrow located on the
front of the unit. (Note: Single North American or
Metric fuse placement is always on the side of the
desired voltage selection arrow behind the fuse
symbol; the other compartment may be used as a
spare or be left blank. Dual Metric fusing capability is
available for 220/240 volts only.)
