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
(RCD/RCCB) 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 the first or both of
the symbols shown
below:
Warning
It must be possible to
lock the mains switch in
position 0. Type and
