Isolation from Rack
Isolate the rack mountable devices from the rack by attaching isolation bushings. Fasten a
pair of isolation bushings together to each of the screw holes on the plate or the bracket on the
devices to prevent the devices from touching the rack, and then screw the devices to the rack.
After screwing the devices to the rack, confirm that the devices are electrically isolated. Isolation
bushings are supplied with the rack mountable devices.
CAUTION
When you install the ‘devices with isolation bushings attached’ on a rack or an instrument panel,
do not keep the devices hung on loose screws in an unstable status. Too much force may apply
to the isolation bushings and cause damaged or broken isolation bushings.
Installation Procedure
1. Fasten a pair of isolation bushings together to each of the screw holes on the plate or the
bracket on the device. The tapering end of the isolation bushings must come to the front
side where a screw enters.
2. Using eight M5 screws to fix the device onto the rack or the panel.
