4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
processfitting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.

nameplate.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your VEGAKON 66 additional protection against mois-
ture penetration by leading the connection cable downward in front of
thecableentry.Rainandcondensationwatercanthusdrainoff.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

the measured product and the process temperature.

In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.

Due to agitators, equipment vibration or similar, the level switch can
be subjected to strong lateral forces.
