and galvanically separated to the output. The
HART communication sockets in the front enab-
le a bidirectional transmission of HART signals.
Voltage supply
Wide-range power supply unit with
20 ... 253 V AC/DC for worldwide use.
Detailed information about the power supply
can be found in chapter "Technical data".

Operation

There are no adjustment elements on VEGAT-
RENN 149A Ex. A parameter adjustment of the
connected sensors can be carried out via the
HART communication sockets. The adjust-
ment of the connected sensors is carried out
preferrably via a Windows PC with a parameter
adjustment software such as PACTware and
respective DTM.
3.4 Packaging, transport and
storage
Packaging
Your instrument was protected by packaging
during transport. Its capacity to handle normal
loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists
of environment-friendly, recyclable cardboard.
For special versions, PE foam or PE foil is also
used. Dispose of the packaging material via
specialised recycling companies.
Transport
Transport must be carried out in due conside-
ration of the notes on the transport packaging.
Nonobservance of these instructions can cause
damage to the device.
Transport inspection
The delivery must be checked for completeness
and possible transit damage immediately at re-
ceipt. Ascertained transit damage or concealed
defects must be appropriately dealt with.
Storage
Up to the time of installation, the packages
must be left closed and stored according to the
orientation and storage markings on the outside.
Unless otherwise indicated, the packages must
be stored only under the following conditions:
VEGATRENN 149A Ex • Ex-separator for 4 ... 20 mA/HART
•
Not in the open
•

Mounting

4.1

Mounting instructions

VEGATRENN 149A Ex is designed for carrier
rail mounting (top hat rail 35 x 7.5 according
to DIN EN 50022/60715). Due to its protection
rating of IP 20, the instrument is suitable for
mounting in switching cabinets. It can be moun-
ted horizontally and vertically.
VEGATRENN 149A Ex is a correspon-
ding, intrinsically safe equipment and
must not be installed in hazardous areas.
A safe operation is only ensured if the
operating instructions and EG type ap-
proval certificate are observed. VEGAT-
RENN 149A Ex must not be opened.
A distance of 50 mm to the intrinsically
safe terminals must be ensured when
mounting.

Preparing the connection

Note safety instructions
Always keep in mind the following safety inst-
ructions:
•
Connect only in the complete absence of
line voltage
•
If overvoltages or voltage peaks are
expected, overvoltage arresters should be
installed
Take note of safety instructions for Ex
applications
In hazardous areas you must take note
of the respective regulations, conformity
and type approval certificates of the
