Placement And Rack Mounting; Accessing The Fuse - Fluke 5790A Operator's Manual

•
The air entering the instrument must be room temperature. Make sure that exhaust
from another instrument is not directed into the fan inlet.
•
Clean the air filter every 30 days or more frequently if the 5790A is operated in a
dusty environment. (Instructions for cleaning the air filter are in Chapter 8.)

2-5. Placement and Rack Mounting

You can place the 5790A on top of a workbench or mount it in a standard 19-inch wide,
24-inch (61-cm) deep equipment rack. For bench-top use, the 5790A is equipped with
non-slipping, non-marring feet. To mount the 5790A in an equipment rack, order the
accessory Y-5737 Rack Mount Kit. The rack mount kit comes with rack ears, 24-inch
slides, fasteners, and an instruction sheet.

2-6. Accessing the Fuse

To prevent instrument damage, verify that the correct fuse is
installed in accordance with the line voltage setting.
The line power fuse is accessible on the rear panel. The fuse rating label to the right of
the fuse holder (labeled F1) shows the correct replacement fuse rating for each line
voltage setting. To access the fuse, refer to Figure 2-2 and proceed as follows:
1. Disconnect line power.
2. Insert the blade of a standard screwdriver in the slot of the fuse holder labeled F1.
3. Turn the screwdriver counterclockwise until the cap and fuse pop free.
