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.
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:
The pump does not require any external motor protection.
The motor has integrated over-temperature protection,
which offers safeguarding against overloading that appears
slowly and against blocking according to IEC 34-11: TP 211.
5.1 Supply voltage
1×230 V ±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
Note
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.
