6. Electrical connection
The electrical connections and additional protection
should be carried out by qualified persons in accor-
dance 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 rub-
ber-sheathed cable with a protective ground lead. It is
possible to replace the mains supply cable, see fig. 7.
Fig. 7
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. 8.

6.1 Generator or inverter
Note: The MQ can be powered by a generator or an in-
verter. However, the pump will only operate satisfac-
torily if the generator or inverter generates a true
sinusoidal wave with the necessary power and volt-
age input.
Never make any connections in the
pump terminal box unless the elec-
tricity supply has been switched off for
at least 5 minutes.
Risk of electric shock: This pump is sup-
plied with a grounding conductor and
grounding type attachment plug. To
reduce the risk of electric shock, be cer-
tain that it is connected only to a
properly grounded electrical circuit
equipped with a ground fault inter-
rupter device.
This pump is not intended, nor has it
been investigated for use in swimming
pool 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 fig. 9).
For indoor use only.
