3.4.2 Installing the KPG pump
•
Take particular care when installing the pumps,
as the procedure is not similar to that of other
submersible pumps.
•
To install the pump in the gate, lift the pump
horizontally by the lifting eyes on the outlet
casing, see fig.
.
•
Only use certified lifting equipment when lifting
the pump.
Proceed as follows:
1. Make sure the cables are not damaged during
the installation.
2. Make sure the lifting eye bolts are correctly
installed and tightened in the pump before lifting
the pump.
3. Lower the pump in front of the gate to a position
where the centre line of the pump is level with the
centre line of the flange on the pump gate.
4. Make sure the rubber gasket at the gate flange is
correctly positioned.
5. Position the motor on the flange on the gate.
6. Slide the pump onto the gate flange.
7. When the pump is in place and the holes in the
pump flange and gate flange are aligned, bolt the
two flanges together.
8. Secure the cables to a flexible cable tray or
similar.
– Make sure the cables can adapt to the different
positions of the gate without being damaged.
– The weight of the cables is significant. Make
sure the stress on the cables is taken by a
flexible cable tray.
3.5 Electrical connection
The supply voltage and frequency are marked on the
nameplate. Make sure that the motor is suitable for
the power supply available at the installation site.
Connect the pump to an external main switch
ensuring all-pole disconnection with a contact
separation according to EN 60240-1, 5.3.2.
Connect P1, P2 and P3 in series with the thermal
protectors and moisture sensors. See section

DANGER
Crushing of hands
Death or serious personal injury
- Do not put your hands or any tools into
the pump inlet or outlet after the pump
has been connected to the power
supply, unless the main switch has been
locked in position 0/Off.
Carry out the electrical connection in
accordance with local regulations.
The pump must be connected to a motor-
protective circuit breaker, for example MP
204.
A phase sequence relay is recommended
in case of possible changes in the phase
sequence from the power supply company.
