Mounting and maintenance
4.2 Rail mounting
All additional supplementary modules can be connected in the same way to the
supplementary module to the left.
Note
The power supply system can be mounted in a control cabinet on standard mounting rails
according to EN 60715. For stability reasons, it is recommended that the TH35-15 version
(15 mm deep) is used. The TH35-7.5 (7.5 mm deep) version has been released for use with
the power supply system. However, when installing the standard mounting rail with a depth
of 7.5 mm, it is crucial that a suitable number of mounting points (dependent on the system
configuration and therefore the total weight) is used so that the standard mounting rail does
not twist.

Installation of the unit in a hazardous zone
