The pump does not require any external motor protection. The motor has integrated over temper-
ature protection, which offers safeguarding against overloading that appears slowly and against
blocking according to IEC 34-11: TP 211.
5.1
Supply voltage
1×230V ±10%, 50 / 60 Hz, PE
The voltage tolerances are set for equalising voltage 0uctuations on the mains. They are not for
operating pumps with voltages other than those shown on the nameplate.
5.2
Connection of the power supply
The pump must be protected on-site (10 A, slow) and must be connected to an external mains
switch. All cables used must have a heat resistance of up to 85 °C. They must not be in contact
with the pipe or the pump and motor casing.
All cables must be connected in accordance with EN 60204-1 and EN 50174-2: 2000. The electrical
connection must be made as indicated on the nameplate.
