8. Electrical connection
The electrical connections and additional pro-
tection should be carried out by qualified per-
sons in accordance with local regulations.
The operating voltage and frequency are
marked on the nameplate. Make sure that the
motor is suitable for the electricity supply on
which it will be used.
The pump must be connected to the mains via
a sheathed cable with a protective ground
lead. It is possible to replace the mains supply
cable. See fig. 10.
Fig. 10 Electrical connection
Connect the mains supply cable of the pump
to the electricity supply. When the cable is
connected, a red and a green indicator light on
the control panel will be on. See fig. 11.

8.1 Generator or inverter
WARNING
Non-submersible pump.
If the power cord is damaged, it
must be replaced by the manufac-
turer, an authorized service center
or by a qualified person in order to
avoid risks.
Never make any connections in
the pump terminal box unless the
electricity supply has been
switched off for at least 5 minutes.
Risk of electric shock:
This pump is supplied with a
grounding conductor and ground-
ing type attachment plug.
To reduce the risk of electric
shock, install only on circuit pro-
tected by a Ground-Fault-Circuit-
Interrupter (GFCI).
This pump is not intended, nor has
it been investigated for use in
swimming pool or marine areas.
This pump has been evaluated for
use with water only.
Do not start the pump until it has
been filled with water (primed, see

Note
The MQ can be powered by a gen-
erator or an inverter. However, the
pump will only operate satisfacto-
rily if the generator or inverter
generates a true sinusoidal wave
with the necessary power and volt-
age input. The generator must be
sized 10 % above the P1
(input power) of the pump. For P1,
see section 12.1 Dimensions.
