Safety and Preparation for Use
WARNING!
Dangerous voltages, capable of causing injury or death, are
present in this instrument. Use extreme caution whenever the
instrument is cover is removed. Do not remove the cover while
the unit is plugged in to a live outlet.
Caution
This instrument may be damaged if operated with the LINE VOLTAGE SELECTOR set
for the wrong AC line voltage, or if the wrong fuse is installed.
Line Voltage Selection
The DS360 operates from a 100, 120, 220 or 240 Vrms AC power source having a line
frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify
that the LINE VOLTAGE SELECTOR, located in the rear panel fuse holder, is set so
that the correct AC input voltage is visible.
Conversion to other AC input voltages requires a change in the fuse holder voltage card
position and fuse value. Disconnect the power cord, open the fuse holder cover door and
rotate the fuse-pull lever to remove the fuse. Remove the small printed circuit board and
select the appropriate operating voltage by orienting the printed circuit board so that the
desired voltage is visible when pushed firmly into its slot. Rotate the fuse-pull lever back
into its normal position and insert the correct fuse into the fuse holder.
Line Fuse
Verify that the correct fuse is installed before connecting the line cord. For 100/120
VAC, use two ½ Amp fuses and for 220/240 VAC use two ¼ Amp fuses.
Line Cord
The DS360 has a detachable, three-wire power cord for connection to the power source
and to a protective ground. The exposed metal parts of the instrument are connected to
the outlet ground to protect against electrical shock. Always use an outlet which has a
properly connected protective ground.
Power Switch
The power switch is located on the front panel of the unit, in the lower right hand corner.
Turn on the unit by pressing the switch in.
Fan
The fan in the DS360 is required to maintain proper operation. Do not block the vents in
the chassis or the unit may not operate properly.
