4.2
Mounting the communications module
Introduction
The communication modules are designed for mounting on a flat, solid surface. Alternatively,
you can use the axially symmetrical drill holes of the modules to fasten them to an aluminum
profile using sliding blocks.
Note
Functional ground
If a grounded metal mounting surface is used, the bottom mounting screw of the RF166C
module already establishes a reliable grounding connection. This eliminates the need for a
separate ground conductor. If you use the fixing screw as grounding connection, the thread
of the fixing screw or the contact facing of the fastening nut on the base must be unpainted.
This ensures a low-resistance connection.
Requirements
The following table shows and explains the types of screws you need to mount the modules.
