3.6 RECOMMENDATIONS
Before commissioning the system, it must be ensured that the installation of the system complies with the
technical guidelines and national laws.
The control elements must be installed in such a way that the functions they set in motion can be monitored by
the operator.
The highest priority is the safety of humans and animals.
Failure to do so could result in serious, permanent injury.
All electrically conductive system components must be connected to the building’s potential
equalization.
