Installation instructions
(continued) • If the active intrinsically safe communication circuits (input/output option S, T; terminals 26/27 resp.
24/25) are fed into areas that require 1D or 2D apparatus, the connected apparatus must be tested and
certified accordingly.
• In Zone 0, potentially explosive vapor/air mixtures may only occur under atmospheric conditions. If no
potentially explosive mixtures are present, or if additional protective measures have been taken according
to EN 1127-1, the devices may be operated under other atmospheric conditions in accordance with the
manufacturer's specifications.
Turning the transmitter housing
1. Unscrew the grub screw.
2. Rotate the transmitter housing cautiously clockwise until the end stop (end of the thread).
3. Rotate the transmitter housing counter-clockwise (max. 360°) in the wanted position.
4. Tighten the grub screw again.

EC type-examination
certificate,
directive 94/9/EC
and COC certificates of
conformity (IEC) EC type-examination certificate, directive 94/9/EC
The system meets the fundamental health and safety requirements for the design and construction of devices
and protective systems intended for use in potentially explosive atmospheres in accordance with appendix II
of directive 94/9/EC.
Certification number: DMT 00 ATEX E 074 X
COC certificates of conformity (IEC)
By affixing the certification number the conformity with the following standards

(depending on the device version) is certified:

Caution!
The explosion group for the communication circuits of the measuring device is IIC. However, it is reduced to
IIB if the permitted, external capacitance/inductance for the intrinsically safe communication circuits is incre-
ased (

Description of measuring
system The measuring system consists of transmitters and sensors. Two versions are available:
• Compact version: transmitters and sensors form a mechanical unit.
• Remote version: transmitters and sensors are separated by open ground when installed and connected to
each other via a connecting cable.
