Ex-separating chamber
To ensure sufficient air and creeping dis-
tances, an Ex-separating chamber must be
mounted to the VEGATOR connections. Loop
the lines through the Ex-separating chamber
and connect the lines. Fasten the Ex-separat-
ing chamber with the lower hold screw.
Please note the operating instructions of the
BGT 596 carrier.
Mounting in carriers
When mounting VEGATOR with Ex-approval
in a carrier, you have to use a VEGA-Ex-
module. Keep a distance of at least 10 mm (2
TE) to module cards of other manufacturers.
If you want to mount VEGATOR in the far left
position in the carrier, you have to mount a
blind cover of at least 20 mm (4 TE) first, and
then you can mount the instrument module.
Protection in Ex-applications
In Ex-applications, a protection of IP 20
should be maintained. Cover the gaps or free
modules at the front by appropriate blind
covers.

Coding
The multiple plug of the instrument is pro-
vided with one or several coding holes to
avoid the interchanging of different instru-
ments.
A fixed coded pin on the Ex-module ensures
that only the Ex-instrument can be inserted.
Two additional coded pins are attached to the
module to avoid the interchanging of differ-
ent instruments. Insert the attached coded
pins into the appropriate holes on the
multipoint connector. The coded pins must be
inserted in the following positions:
