2.2 Mounting and installation
FRA5087 2-4
2.2.3 Rack mounting
The FRA5087 Frequency Response Analyzer can be mounted on the 19-inch IEC, EIA or JIS
standard rack by the use of a rack-mount adapter (option).
First, mount the rack-mount adapter on the instrument as shown in
“Fig. 2-2 Mounting
rack-mount adapter” , and then, mount the instrument on the rack.
Remove foot-stands from the instrument by placing it upside-down as shown in “Fig. 2-3
Removal of foot-stands”, when the foot-stands interfere with the bottom of the rail.
Following attention should be drawn when you mount the instrument on the rack:

Support the instrument by all means by installing some supports such as rails on the rack.

Do not mount this instrument on an enclosed rack; otherwise, internal temperature rises high
enough to induce operational failures.
Prepare ventilation openings on the rack, or install an air flow system in the rack by using a
fan.
If you install other equipment above and/or below this instrument in the rack, secure the
space of 40 mm at minimum between the lower equipment for ventilation purposes.

A space above the FRA5087 is required for replacing the thermal paper roll when the built-in
thermal printer is used.
See “Figure 9-6 External Drawing” for how to secure a space that allows the lid of the printer
unit to be opened and closed.
