5 Electrical connection
Electrical connection should be carried out in accordance with the local regulations.
It is vital to ensure that the voltage and frequency indicated on the nameplate are compatible
with the mains supply available.
Warning
Before carrying out any electrical connection work, the voltage supply must be
switched off.
The pump must be connected to an external network switch with a contact opening
on all poles of minimum 3 mm.
The protection against indirect contact can be achieved by earthing or potential
equalisation.
The pump does not require any external motor protection. The motor has integrated over-tempe-
rature protection, which offers safeguarding against overloading that appears slowly and against
blocking according to IEC 34-11: TP 211.
5.1 Additional safety features
If the pump is connected to an electrical installation, which has an FI circuit breaker for additional
protection, the FI circuit breaker must trigger with a pulsing direct current component if earthing
fault currents arise.
The FI circuit breaker must be marked with the following symbol:

FI FI
5.2 Supply voltage
1×230V ±10%, 50 / 60 Hz, PE
The voltage tolerances are set for equalising voltage fluctuations on the mains. They are not for
operating pumps with voltages other than those shown on the nameplate.
With direct mains connection, the pump may not be switched on and off at the
mains more than four times an hour. If the pump is switched on directly via the
mains, it only starts after a 5-second delay.
