2 Safety
2.1 General safety notes
The manuals for the system and parts thereof as well as the maintenance records and handover certificates must be kept
available near the system.
During installation, operation, maintenance or repair of the system, the regulations for the prevention of accidents, the perti-
nent DIN and VDE standards and directives, as well as the directives of the local power supply industry must be heeded.
NOTICE
Disconnect system from energy sources!
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 regulations concerning electrical safety apply to all connections and installation work.
The system must be supplied through a residual current protection device (RCD) with residual current of not
more than 30mA.
The control unit and the float switch or level control 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.
2.2 Personnel - qualification
The relevant operational safety regulations and the hazardous substances ordinance or national equivalents apply for the
operation of the system.

2.3 Intended use
The control unit represents the control of a lifting station or a pumping station for wastewater. Probes, float switches or pres-
sure sensors can be used to detect the level. When the switching level has been reached, the pump-off function is activated.
