4.5 Electrical connection

• The electrical connection of the pump should be
carried out by qualified persons in accordance
with local regulations.
• For electrical data of the pump, see section
3.2 Electrical data.
• Do not lay signal cables, if any, together with
power cables.
Warning
Danger to life due to non-tripping of the
residual current device (RCD)!
If the pump is connected to an electric
installation where a residual current device
(RCD) is used as an additional protection,
this RCD must trip when earth fault
currents with DC content (pulsating DC)
and smooth DC earth fault currents occur.
This means that a RCD type B, sensitive to
universal current, must be used.
