3.9 Additional instructions for Ex-

applications

Applications in the range acc. to
- the CENELEC Ex-regulations
- the ElexV (Germany) Zone 0
require the use of approved sensors.

For these applications the appropriate legal
documents (test reports, test and conformity
certificates) must be observed. These are
supplied with the appropriate instrument.

The voltage supply of these sensors must
only be made via an intrinsically safe circuit.
For this purpose, the sensors are connected
via appropriate separating facilities to the
appropriate VEGALOG-input card:
- to the EA-card via a safety barrier type 145
- to the EV-card via a safety barrier type 146

or VEGATRENN 546, or via an Ex-separa-
tor VEGATRENN 547V␣ Ex, or VEGATRENN
548V␣ Ex

Please also observe the legal documents of
these instruments.

Electrical connection

Mounting instructions

Please observe the following instructions for
mounting:
- VEGALOG 571, as well as the used sepa-

rating facility, must only be mounted out-
side the Ex-area

- a separating wall must be added between

connection parts of intrinsically and not-
intrinsically safe circuits, so that there is a
min. distance 50 mm

- max. five safety barriers type 146 or VE-

GATRENN 546 can be connected to one
EV-card

- only one sensor must be connected to

each separator or safety barrier

- a 32-pole Ex-module with 10 TE width must

be provided in the carrier for each
VEGATRENN 546 separator

- if the carrier is equipped with VEGATRENN

546, the following spaces must be kept:
-

⊕

 10 mm to the left carrier wall (is en-

sured by blind cover 4 TE = 20,32␣ mm)

-

⊕

 6 mm to the non-Ex-component co-

ordinated on the left (is ensured by blind
cover 2 TE = 5,08 mm)

In addition, the valid mounting and operating
instructions must be observed. The DIN/
VDE-regulations, for example, prescribe that
the connection lines between separating
system and sensor must be marked on their
entire length. A light-blue colour must be
used for wrapped cable.
