3.7 Electrical connection

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.
