Power connection
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with relevant regulations.
WARNING Electrocution
The connection to the power supply is only permissible
as a permanent connection in conjunction with the re-
movable cable entry. Ensure that the appliance can be
separated from the power supply by an isolator that dis-
connects all poles with at least 3 mm contact separation.
WARNING Electrocution
Ensure that the appliance is earthed.

Observe the type plate. The specified voltage must match
the mains voltage.
f Undo the screws at the bottom of the control panel cover and
f
remove the cover.
f Select a cable of the cross-sectional area suited to the load
f
of the appliance. Prepare the power cable, ensuring that the
earth conductor is longer than the other conductors.
f Feed the power cable through the cable entry into the control
f
panel.
f Connect the required load in accordance with the wiring
f
diagrams (see chapter "Specification / Wiring diagrams and
connections").
f Fit the control panel cover.

Contactors for thermostats or high limit safety cut-outs
must be installed outside the control panel of the flanged
immersion heater. The contactors must be switched inde-
pendently of one another by the thermostats and the high
limit safety cut-out respectively (see chapter "Specifica-
tion / Wiring diagrams and connections").
If the appliance is operated with power-OFF control, you must
install the power-OFF contact between the contactors or upstream
of the contactor.
Required contactor breaking capacity:
Sizing in accordance with the connected load (see chapter
"Specification / Data table") for l
stant current with a resistive load at an ambient temperature of
up to 70 °C).
f Label the contactors according to their function.
f
f If required, mark any live components inside the control
f
panel that are supplied with power from outside.
f Once connected, check that the contactors are functioning
f
properly.

Boiling dry destroys the thermostat, which must then
be replaced. The high limit safety cut-out must be reset.
Material losses
!
If an indirect coil is installed in the same cylinder, limit
the maximum temperature for this appliance to the maxi-
mum temperature for the flanged immersion heater. This
prevents the high limit safety cut-out of the flanged im-
mersion heater from responding.
Appliance handover
f Explain the appliance function to users and familiarise them
f
with its operation.
f Make users aware of potential dangers.
f
f Hand over these instructions.
