connection of any 4 ... 20 mA sensor. The
instrument is suitable for carrier rail, panel and
surface mounting.
Functional principle
The VEGAMET 381 signal conditioning instrument
can power connected sensors and process their
measurement signals. The requested measured
variable is shown on the display and also outputted
to the integrated current output for further pro-
cessing. The measurement signal can thus be
transferred to a remote indication or a super-
ordinate control system. Two level relays for control
of pumps or other devices are also integrated.
Voltage supply
Wide-range power supply unit with 20 ... 253 V AC/
DC for world-wide use.
Detailed information about the power supply can
be found in chapter "Technical data".

3.3 Operation

The adjustment of VEGAMET 381 is carried out via
the integrated keys and a 16-step function switch.

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
according to DIN EN 24180.
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 under consideration
of the notes on the transport packaging. Non-
observance of these instructions can cause dam-
age to the device.
Transport inspection

4.1 General instructions

Installation possibilities
The instrument is designed for recessed
installation in a front panel, housing front plate or a
switching cabinet door. The required cut-out is
92 x 92 mm (3.63 x 3.63 in) according to EN 60529.
When installed correctly, protection rating IP 40 is
guaranteed. As an alternative, the instrument can
be mounted into a switching cabinet or housing by
means of four screws (fixed with screws on rear of
housing). A mounting adapter for carrier rail
mounting is optionally available in the scope of
delivery (top hat rail 35 x 7.5 according to DIN
EN 50022/60715).
Information:
If the instrument is mounted via the screws
or carrier rail, it must be always mounted in
a switching cabinet or protective case.
