16.Fix the supply cable to the lifting wire by means of a cable
clamp approx. 0.8 m above the pump. This will prevent the
cable from falling down and becoming entangled in the
impeller during operation. Connect the cable clamp to the
lifting wire above the wire clamp by means of a snap hook.
See fig. 12. Attach the supply cable to the lifting wire by means
of cable clamps placed at 1 m intervals.

Attaching the supply cable to the lifting wire
17.Position the crane in the foot and mount the lifting wire in the
drum of the winch.
18.Lift the complete pump (pump rack with motor) using the crane
and slide it over the column profile.
19.Slowly lower the pump into the tank and down to position on
the connection flange.
20.Mount the cable sock (pos. 18) to the top fixation bracket
using the shackle, and pull the motor cable through it to the
desired position. See fig. 13. The supply cable should be
slightly tightened.

21.Dismantle the lifting wire from the winch and fit it to the wire
clamping (pos. 20) on the top fixation bracket.
Use the lifting wire as a relief for the supply cable. For this
reason, the lifting wire must always be tightened.
22.Connect the supply cable to the terminals in the control
cabinet.
7. Electrical connection
The electrical connections must be carried out by a qualified
electrician in accordance with local regulations.
All national and local regulations relating to safety and accident
prevention must be observed.
The supply voltage and frequency are marked on the pump
nameplate. Make sure that the pump is suitable for the power
supply available at the installation site.
The pump is supplied complete with a supply cable of 10 metres
(standard length, suitable for up to 7 m deep tanks).
The motor is marked either with a Y (star) or
Δ
(delta). Make this
connection in an external control panel using conductors 1 to 6 of
the supply cable.
Fig.14 shows a schematic drawing of these star and delta
connections. See also section
If the pump is connected in delta during operation, the pump can
be started in star-delta starting.

Caution
Dismantle the lifting wire from the crane before
starting the pump.
Warning
Make sure the power supply to the control
cabinet has been switched off.
Warning
Before making any electrical connections, make
sure that the fuses have been removed or the
mains switch has been switched to off. Make sure
that the power supply cannot be accidentally
switched on.
Warning
The explosion protection classification applies
only to versions for 400 V, 50 Hz.
The explosion protection classification is Ex e ck
ib IIC T3.
The classification of the installation must be
approved by the local authorities in each
individual case.
The safety instructions in section 4.2 Explosion-
proof versions must be observed.
