Installation, Wiring - Kessel Aqualift F Mono Installation Manual

Only qualified electricians may carry out the work on el-
CAUTION:
ectrical equipment described below. Before any work is
carried out on the switch unit, the pump or level control,
the main switch and fuses must be switched off, i.e. be vol-
tage-free and secured against being switched back on
again
5.1 General instructions
An external main switch must be installed for the electric
switch unit that can be used in an emergency to switch off all
the downstream circuits independently of the control unit.
This must be assigned clearly to the switch unit.
All connected cables must be strain-relieved.
Screw connections not used must always be sealed properly.
All the cables connected to the electrical switch unit must
IMPORTANT:
be fixed in place using suitable measures (e.g. cable ties)
so that they do not cause a hazard in the 1-error case, i.e.
if a connection becomes loose..
Please heed national and local safety regulations. If these
are not observed, personal hazard may be the result. In ad-
dition, no liability or warranty will be granted. After work has
been completed, the housing cover must be sealed properly
again.
5.2 Mounting the switch unit
Screw the housing cover with max. 1 Nm. Install the switch
unit provided in a frost-free, dry, flood-proof and well-venti-
lated room. The switch unit has been designed for vertical
wall-mounting on a solid base. Sufficient air circulation must
ensure excessive inside temperatures develop. The unit is
mounted using 4 screws (Ø 6 mm) at the corners of the hou-
sing (drilling template in the packaging box). The attachment
holes are accessible after the cover has been opened.

5.3 Installation, wiring

The pump cables and control cable have a standard length
of 5 m. Extension to max. 20 m is possible on site, but must
be done using a VDE-conform connection.
NOTE applies to pressure diaphragm switches up to model
year 01/10)
The cable on the pressure level switch is a special cable with
an air hose in the centre for compensating pressure for the
pressure sensor in the lifting station to the atmosphere. The
following must always be observed:
– The cable may be cut off at any point but must never be
extended. Special lengths of this cable can be ordered di-
rectly from KESSEL.
– The cable must be routed at a constant gradient from the
switch unit to the lifting station.
For this reason, excess lengths must not be rolled up, the
cable has to be shortened to fit.
– The respective screw connection at the switch unit may be
tightened with a maximum torque of 2.5 Nm. Greater torques
can lead to the air hose being squeezed.
– Deviations from these instructions can lead to fun-
ctional failure of the pressure sensor and thus the
whole system!
