Notes for the field installation
The modules are to be mounted on a flat surface, each with or at least with two screws.
Type of mounting
Screws
Torque

Nm
With all types of mounting a flat washer according to DIN 125 has to be
used.
Important note:
For the derivation of interference currents and/or for the EMC stability the module provides a metal
grounding sheet.
It is necessary to connect this metal grounding sheet by a low impedance connection to the
reference earth. In case of a grounded mounting surface the connection can be set up directly
through the mounting screws (not with laterally mounting).
With a not grounded mounting surface or lateral mounting a ground strap or a suitable PE-cable has
to be used.
