Rear Panel Features

Power Entry Module
The power entry module is used to fuse the AC line, select the line voltage and block
high frequency noise from entering or exiting the instrument. The DS360 uses a
detachable three wire power cord for connection to the power source and the protective
ground. All exposed metal parts of the unit are tied to the outlet ground to protect against
electrical shock. Always use an outlet which has a properly connected protective ground.
Caution
This instrument may be damaged if operated with the LINE VOLTAGE SELECTOR set
to the wrong AC line voltage, or if the wrong fuse is installed.
Do not attempt to service or adjust this instrument while it is plugged into a live outlet.
Line Voltage Selection
The DS360 operates from a 100, 120, 220 or 240 V
having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power
source, verify that the LINE VOLTAGE SELECTOR card, located in the rear panel fuse
holder, is set so the correct AC input voltage is visible.
Conversion to other AC sources requires a change in the fuseholder voltage card position
and fuse value. Disconnect the power cord, open the fuse holder and rotate the fuse lever
to remove the fuse. Remove the small printed circuit board and select the operating
voltage by orienting it so the correct voltage is visible when pushed back into its slot.
Rotate the fuse-pull lever back to its normal position and insert the correct fuse into the
holder.
Line Fuse
Verify that the correct fuse is installed before connecting the line cord. For 100/120
V use two ½ amp fuses. For 220/240 V
