VEGATOR
Ex version
Ex separating chamber
An Ex separating chamber must be mounted
to the connections of VEGATOR to ensure
sufficient "air and creep distances". Feed the
cables through the Ex separating chamber
and connect them. Fasten the Ex separating
chamber with the lower retaining screw. Note
the operating instructions of the carrier BGT
596.
Mounting in carriers
If you are mounting a VEGATOR with Ex
approval in an assembly carrier, you must
use a VEGA-Ex module. Leave a distance of
min. 10 mm (2 TE) to modules of other manu-
facturers. If VEGATOR is to be mounted in
the carrier at the extreme left position, a blind
cover with min. 20 mm (4 TE) must be
mounted to the left of the module.
Protection for Ex applications
For Ex applications, protection IP 20 must be
maintained. To do this, cover gaps and
empty slots with blind covers.

Coding
The multipoint connector of the instrument is
provided with one or more coding holes to
prevent incorrect module insertion.
A fixed coded pin on the Ex module ensures
that only Ex instruments can be inserted.
Two additional coded pins are enclosed with
the module to prevent incorrect insertion of
other instruments. Insert the attached coded
keys into the holes on the multipoint connec-
tor. The coded keys must be plugged into
the following positions:
