1.1 Function, configuration and
mounting
Function
Ex-separator VEGATRENN 548 V Ex is used
for intrinsically safe, galvanically isolated
supply of up to 15 digital (VBUS) presure
transmitters. At the input side it is connected
to the tow-wire-VBUS-line of the signal
conditioning instruent and provides at the
output side 15 intrinsically safe ia-circuits.
The Ex-separator can be used in conjunction
with the following signal conditioning
instruments or sensors:
- VEGAMET 514 V and 515 V
- EV-card of VEGALOG 571
- pressure transmitter D80, D81, D84 or D86
in Ex-version with VBUS-electronics E23V
The ia-circuits are divided into 3 branches, up
to five sensors can be connected to each
branch. The ia-circuits are galvanically
connected and a fuse per branch is used for
safety reasons.
The intrinsically safe circuits are galvanically
isolated from the not intrinsically safe circuits.

Mounting
The Ex-separator VEGATRENN 548 V Ex can
be mounted as follows:
- in carrier BGT 596 Ex or BGT LOG 571
- in housing type 506
Mounting in carrier
First of all mount the Ex-module inot your
carrier. The Ex-module consists of a multipoint
connector acc. to DIN 41 612, individual
coded pins (see drawing), a separating
chamber as well as guide rails and mounting
material.
Wire the connections of the multipoint
connectro acc. to the wiring place on the
following pages.
The multipoint connector is available as
follows:
- Wire-Wrap standard connection
1,0 x 1,0 mm
- Plug-connection 2,8 x 0,8 mm
- Termi-Point standard connection
1,6 x 0,8 mm
- Soldering connection
- Screw terminals 2 x 0,5 mm
2
Further information concerning mounting is
stated in the operating instruction of the
carrier.
Mounting in single housing
The housing socket can be either screwed
directly to a mounting plate or plugged on a
carier rail (TS 35 x 7,5 acc. to EN 50 022 or
TS 32 acc. to EN 50 035). Further information
concerning mounting are stated in the
operating instruction of the housing. Connect
the wires acc. to the wiring plan.
Coding
The multipoint connector of the carrier or the
housing must be provided with coded eys to
avoid interchanging of the various signal
conditioning instruments. The multiple plug of
VEGATRENN is povided with the appropriate
holes (mechanical coding).
The instrument coding ensures that the
various signal conditioning instruments are not
interchanged. The appropriate coded pins are
attached to each module or housing. Provide
the multipoint connector with these coded
pins acc. to the following table and figure.
The Ex-coding with fixed coded pin ensures
that not-Ex and Ex-intruments are not
interchanged.

3.1 Installationinformation
Generally the following instructions must be
noted for installation:
Installation place
VEGATRENN 548 V Ex as well as the
apropriate signal conditioning instrument must
be generally instaled outside the hazardous
areas.
Protection
In Ex-applications protection IP 20 must be
maintained. Cover the gaps or free modules
from the front with appropriate blind covers.
Ex-separating chamber
An Ex-separating chamber must be mounted
to the connections of VEGATRENN to ensure
sufficient „air and creeping distances“. Loop
the cable through the Ex-separating chamber
and connect the cables. Fasten the Exseparating chamber with the lower screw.
Note the operating instruction of the carrier
BGT 596 Ex.M.
Mounting in carrier
When you mount VEGATRENN 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. When you want
to mount VEGATRENN in the complete left
position in the carrier, a blind cover of at least
20 mm (4 TE) must be mounted in front of the
module of the instrument.

VEGATOR
Blind cover
Separation from not intrinsically safe
circuits
A separating wall must be provided between
the connection parts of intrinsically safe and
not intrinsically safe circuits so that the min.
distance of 50 mm must be kept. When using
a separating chamber (supplied with the
module) this condition is met.
General conditions
In addition the valid „Installation and operating
instructions“ as well as the special conditions
and instructions in the conformity certificates
must be noted.

3.2 Connection instructions
Not intrinsically safe input
The not intrinsically safe input of the Exseparator is connected via a standard twowire line with a signal conditioning instrument.
If electromagnetic interferences have to be
expected, screened cable should be used.
The screen must only be earthed a one end of
the signal conditioning instrument.
Intrinsically safe output
The wiring of the intrinsically safe outputs of
the Ex-separator with the sensors must meet
with the valid installation regulations. E.g. the
DIN-regulations prescribe that the connection
lines between Ex-separator and sensors must
be marked on the entire length. For coverings
light blue must be used as colour.
If electromagnetic interferences must be
expected, screened cable must be used. The
screen must only be earthed at one sensor
end.
