(3) Attaching Modules in Intense Vibrating Environments
If the modules are used in intense vibration environments, fasten the modules with a
screw as shown in Figure C2.6. For this, use a screw described below. With a Phillips
screwdriver, tighten the upper side of the module with this screw.
During this operation, the user must tilt the screwdriver somewhat using the guide channel
at the top of the module. A clearance of approximately 80 mm between the module and the
duct above it is necessary to allow the screwdriver to access the screw.
CAUTION
DO NOT overtighten the module fixing screw.
