2 Housing type 506
Product description
1 Product description
1.1 Function and configuration
The housing type 506 is used for single
mounting of a signal conditioning instrument
for VBUS-sensors of series 500 (width 5 TE =
25,4 mm) and, additionally for VEGATRENN
547V Ex or 548V Ex separator also with 5 TEwidth.
The housing can be either screwed directly
to the mounting plate or mounted to a carrier
rail (35 x 15 acc. to EN 50 022).
The housing consists generally of three components:
- Socket with terminals
The connection terminals for the sensors
are located at the bottom and the ones for
the outputs and the power supply on top of
the socket. Therefore, the necessary separation between intrinsically safe and notintrinsically safe circuits in Ex-applications
is ensured. For carrier rail mounting an appropriate adapter is integrated in the socket.
- Upper part of the housing with guide rails
and ventilation slots. Sufficient ventilation is
also ensured when connecting several
housings in series. No external ventilation
necessary.
- The attached bag includes blue Ex-labels
and coded pins.
If you already have a power supply of
20 … 53 V AC or 20 … 72 V DC available,
you can use the housing without power supply unit.
If you only have other supply voltages available, use a housing with integrated power
supply unit.
The power supply unit is suitable for a voltage range of 90 … 250 V AC and DC and
can power the module units.
A later retrofitting of the housing with a power
supply unit is possible.
Note:
The housing type 506 is only designed for
series 500 instruments:
- VEGAMET 514V, 514VD, 515V
- VEGATRENN 547V Ex, 548V Ex
The power supply unit of the housing provides no galvanic isolation from the supply
voltage. Series 500 instruments realise the
galvanic isolation in the signal conditioning
instrument.
The module instruments of the new series
500
- VEGAMET…
- VEGATRENN…
are generally provided for a power supply of
20 … 53 V AC or 20 … 72 V DC.

2 Mounting
2.1 General
The housing type 506 can be screwed directly on a mounting plate (see "Dimensions,
holes") or placed on a carrier rail (35 x 15
acc. to EN 50 022). To do this, it is necessary
to loosen the two screws on the front of the
housing and to remove the upper part of the
housing from the socket.
For placing on carrier rail or loosening from
the carrier rail, unlock the holding strap with a
screwdriver in the lower rectangular opening
of the socket.

Mounting
2.2 Coding with Ex-instruments
To avoid a not-Ex-instrument being inserted
into the housing instead of the separator, the
right multipoint connector of the housing is
provided with a coded pin (position c23). A
hole is provided in the appropriate position
on the multiple plug of the VEGATRENN 547V
Ex and 548V Ex separators.
2.3 T ransparent cover
The module units can be provided with a
lockable transparent cover to avoid unauthorised adjustment.
The transparent covers are supplied along
with the module units.
2.4 Retrofitting of the housing with a
power supply unit
Please proceed as follows to retrofit a power
Wire the terminals acc. to the connection plan
(see either "3 Electrical connection", or the
operating instructions of the signal conditioning instrument to be installed, or the separator).
The designations of the terminals correspond
to those on the multipoint connector on the
rear of the signal conditioning instrument. The
exceptions are the sensor connection terminals, see "3 Electrical connection".

supply unit:
- First of all make sure that the supply volt-
age is disconnected on the terminal strips
of the socket!
- Loosen the two hold screws on the front of
the housing and remove the upper part of
the housing (the hold screws are only
accessible when there is no module card in
the housing).
- Shift the power supply board into the guide
rails of the upper part of the housing. Note
the position of the connection plug.

- Insert the red safety pin through the gaps
of the power supply board and the guide

- Remove the adapter plug from the housing
socket.
- Insert the upper part of the housing into the
socket again, tighten the two screws on the
housing front.
- Now you can connect the supply voltage
for the power supply unit (90 … 250 V AC)
on the terminal strips of the socket.

The designations of the terminals are identical
to those on the multiples plugs of the signal
conditioning instruments. Exception: Sensor
