Once the fuse drawer has been removed from the instrument slide out the fuse from the holder

1.4.4 Safety Inspection

Before operating the instrument inspect the power inlet module on the rear of the Sentry Plus to
ensure that the properly rated fuse is in place, otherwise damage to the unit is possible. Make
sure that the voltage selector switches are set in accordance with the power source in use. Refer
to paragraph 1.4.3 and Figure 1-5.
The Sentry Plus instrument is shipped with a standard U.S. power cord, QuadTech P/N 4200-
0300 (with Belden SPH-386 socket or equivalent, and a 3-wire plug conforming to IEC 320).
Make sure the instrument is only used with these cables (or other approved international cord
set) to ensure that the instrument is provided with connection to protective earth ground.
The surrounding environment should be free from excessive dust to prevent contamination of
electronic circuits. The surrounding environment should also be free from excessive vibration.
Do not expose the Sentry Plus instrument to direct sunlight, extreme temperature or humidity
variations, or corrosive chemicals.
