4. Electrical installation
Carry out the electrical connection and protection according to
local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
Warning
Switch off the power supply before making
connections.
Warning
The pump must be connected to an external
mains switch with a minimum contact gap of
3 mm in all poles.
Earthing or neutralisation can be used for
protection against indirect contact.
If the pump is connected to an electric
installation where an earth leakage circuit
breaker (ELCB) is used as an additional
protection, this circuit breaker must trip when
earth fault currents with DC content
(pulsating DC) occur.
The earth leakage circuit breaker must be marked
with this symbol:
•
The pump must be connected to an external mains switch.
•
The pump requires no external motor protection.
•
The motor incorporates thermal protection against slow
overloading and blocking (IEC 34-11: TP 211).
•
When switched on via the power supply, the pump will start
pumping after approx. 5 seconds.
The number of starts and stops via the power
Note
supply must not exceed four times per hour.
4.1 Supply voltage
1 x 230 V ± 10 %, 50/60 Hz, PE.
The voltage tolerances are intended for mains voltage variations.
They should not be used for running pumps at other voltages than
those stated on the nameplate.
