Ensure that the electrical components are disconnected from the electrical power supply during the work.
WARNING
Live parts!
Heed the following points when working on electrical cables and connections:
The national safety regulations apply for all electrical work on the system.
The system must be supplied through a residual current protection device (RCD) with residual current of not

Operate the system only in buildings in which an overvoltage protection system (e.g. surge arrestor, type 2 per
VDE regulations) is installed. Interference voltage can seriously damage electrical components and lead to sys-
tem failure.
