voltage and frequency available at the installation
site.

accordance with local regulations.
Warning
The product must be earthed. 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.
The installation must include an earth
leakage circuit breaker for protection
against earth fault currents. This will
ensure protection when using a Schuko
plug or another plug with earth pin.
