Mounting The I/O Module - Siemens RF182C Operating Instructions Manual

Mounting

3.2 Mounting the I/O module

3.2 Mounting the I/O module
Features
● The base unit is mounted on a stable surface
Note
Functional ground (PE)
If a grounded metal mounting surface is used, the bottom mounting screw of the RF182C
module already establishes a reliable grounding connection. This eliminates the need for
a separate grounding cable. 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.
