Stand-alone inverters are used in autonomous power
supplies, e.g. solar power supply, and can generate over-
voltages. Overvoltages can destroy the pump.
ƒ A multiple plug socket or power strip is in use
ƒ An energy-saving plug is in use
This reduces the energy supply to the pump and the pump
may heat up too much.
5.3.1 Connection: Pump with plug
Provide a socket outlet with earthing contact. To connect
the pump, insert the plug into the socket.
NOTICE
Pump starts up or is ready for operation!
Once the plug is connected to the socket, the
pump will either start immediately or be ready
for operation:
• Pump without float switch: pump switches

• Pump with float switch: pump is ready for
operation and will switch on depending on
the fill level!
▶ We recommend switching the socket on
and off using a separate main switch!
