Notes on Installation
CAUTION
For safety during installation, secure an ample working space and work in a team. Be sure to
observe the following when installing on a rack or on an instrumentation panel:
Insulation from Rack
The safety control unit or safety node unit or Unit for Optical Bus Repeater Module must be
insulated from the rack using insulating bushing to prevent direct contact. Place the bushing on
both sides of the plate, as shown in the figure below. Make sure that the rack-mounted equipment
is electrically insulated from the rack. Insulating bushing is supplied as an accessory.
When you mount a device with insulating bushing to a rack, please do not leave it in an unstable
condition where it is only hooked with loose screws. It may add unnecessary force to an
insulating bushing to cause breakage.
Installation Procedure
1. Fasten a pair of insulating bushings together to each of the screw holes on the plate or the
bracket on the device. The tapering end of the insulating 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.
