1. Disconnect line power.
2. Observe what line voltage setting is displayed in the PEM window. If it is correct, the fuse assembly
will be re-inserted in the same orientation it is removed. Otherwise, it will need to be rotated 180°
before re-insertion.
3. Open the fuse compartment by inserting a screwdriver blade in the slot located at the top of the fuse
compartment and open the PEM door.
4. Use the screwdriver blade to pry out the fuse block by inserting the blade in the slot located at the top of
the fuse block.
5. Remove the fuses from the assembly for replacement or verification. Be sure the correct fuses are
installed.
6. Reinstall the fuse assembly by pushing it back into the PEM while ensuring that the correct line voltage
label is shown in the PEM window. Close the PEM door so it locks in place.

3.4 Connecting to Line Power
WARNING: To avoid electrical shock, connect the factory supplied three-prong line power cord to a
properly grounded power outlet. Do not use a two-prong adapter or extension cord that will break the
ground connection.
After the line voltage setting and correct fuse are veried, connect the instrument to a properly grounded
three-prong outlet using the provided line voltage cord.
3.5 Placement and Rack Mounting
In general, place the Super-Thermometer in an area free of drafts and excessive electrical noise. Refer to the
specications for environmental requirements.
The Super-Thermometer is designed to be used on a bench-top or installed in a standard width rack with the
optional rack mount kit. For bench-top use it is equipped with hinged, non-slip feet. For rack mount instruc-
