Installation and electrical connection
– Provide a motor protection switch!
Do not connect the pump if:
▪ The connection cable is damaged
Have the connection cable replaced by a qualified electrician or customer service.
▪ A standalone inverter is in use
Standalone inverters are used in autonomous power supply (such as solar power) and
may cause overvoltages. Overvoltages can destroy the pump.
▪ A multiple plug socket or power strip is in use
▪ An energy-saving plug is in use
These reduce the energy supply to the pump which may cause the pump to become
too hot.

Connection: Pump with plug
NOTICE
Pump starts up or is ready for operation!
The connection to the mains is established by inserting the plug into the socket.
Once the plug is connected to the socket, the pump is ready for operation and will
start depending on the fill level!
We recommend switching the socket on and off using a separate main switch!
