DANGER
Risk of death due to electrocution!
Improper conduct when carrying out electrical work can lead to death due to elec-
tric shock! Electrical work must be carried out by a qualified electrician in accord-
ance with the locally applicable regulations.
▪ Power grid with correctly installed protective earth conductor.
▪ RCD (residual-current device) with 30 mA is installed.
▪ Max. fuse protection 16 A.
▪ The technical data of the product (see rating plate) must match the data of the power
grid.
▪ Connection cable with plug:
– Equip socket with earth contact.
▪ Connection cable without plug:
– Electrical connection must be carried out by a qualified electrician!
– Earth the device properly!
– 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.
