Electrical connection

• Install protective earth conductor for mains connection. Obey local regulations.
• Install a residual-current device (RCD) with a trigger current of 30 mA.
• Use fuse protection at the mains connection with a maximum rating of 10 A.
• Make sure that the mains connection is compatible with the voltage (U) and frequency (f) data on the rating plate.

Do not connect the pump under the following conditions:

• The connection cable is damaged.
• To replace the damaged cable, contact a qualified electrician or customer service.
• A stand-alone inverter is used.
• A stand-alone inverter is used in autonomous power supplies, e.g., solar power supply. An inverter can cause overvoltage. Overvoltage destroys the pump.
• A power strip is used.
• An energy-saving plug is used.
• The plug decreases the power supply to the pump. The pump can overheat and be destroyed.
• A start-up control device is used.
• Do not connect the pump to a frequency converter or a soft starter. The pump is not designed for such operation.
• There is a potentially explosive atmosphere. The pump has no Ex approval.
