The accident prevention regulations, the applicable standards and directives as well as the regulations from the local energy
and supply companies must be observed during the installation, operation, maintenance and repair of the system.
NOTICE
Disconnect system from energy sources!
Ensure that the electrical equipment is disconnected from the power supply during the work.
Secure the electrical equipment against being switched on again.
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
more than 30 mA.
The control unit and the float switch or level measuring device are live and must not be opened.
It must be ensured that the electric cables as well as all other electrical system components are in a faultless condition. In
case of damage, the system may on no account be put into operation or must be stopped immediately.
WARNING
Danger due to overvoltage!
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.
CAUTION
Hot surfaces!
The drive motor can develop a high temperature during operation.
Wear protective gloves.
