7. Electrical connection
7.1 Limit contact (optional)
Connect the limit contact, where used, as shown in
the wiring diagram and connect to the electrical
control system.
When connecting inductive loads such as
contactors, relays, etc, it must be ensured that the
electrical limit values are not exceeded, even for
short periods such as with voltage spikes.
To prevent overloading of the reed contact, it is
recommended that a contact protection relay is
used.
7.2 Measurement transducer
Reed contact chain (option ..W..)
Ensure that the electrical power supply is deenergised.
To avoid disturbances from electric fields of other electrical circuits, the cable
should not be laid together with other high voltage cables.
Remove the cover and run the power supply cable through the cable gland.
Connect the measurement transducer to the electronic system in accordance
with the following table.

transducers which have a connector housing.
If connecting the measurement transducer to a Kobold transmitter, such as type
ADI, please read the relevant operating instructions.
