3.6 Electrical connection
DANGER
Electric shock
Death or serious personal injury
Switch off the power supply before you
start any work on the product. Make
sure that the power supply cannot be
accidentally switched on.
The pump must be earthed.
DANGER
Electric shock
Death or serious personal injury
The protective earth of the socket
outlet must be connected to the
protective earth of the pump. The plug
must therefore have the same PE
connection system as that of the
socket outlet. If not, use a suitable
adapter.
We recommend that you fit the permanent
installation with a residual-current circuit
breaker, RCCB, with a tripping current less
than 30 mA.
DANGER
Electric shock
Death or serious personal injury
If the pump is used for cleaning or
other maintenance of swimming pools,
garden ponds or similar places, make
sure that the pump is supplied through
a residual-current circuit breaker,
RCCB, with a tripping current of 30
mA.
DANGER
Electric shock
Death or serious personal injury
Connect pumps that are delivered
without cable and/or plugs to an
external main switch with a minimum
contact gap of 3 mm in all poles.
Make sure that there is at least 3 m free
cable above the liquid level.
Check that the supply voltage and frequency
correspond to the values stated on the pump
nameplate.
The electrical connection must be carried out by an
authorised electrician in accordance with local
regulations.
