Notes on Safe Use of the ATEX Approved Equipment
Approved usage of the meter is restricted to fluids compatible with the wetted materials of the
flow meter and within the restrictions on temperature and pressure as defined in the product
manual.
4.2.
Mounting, Commissioning, and Operation
The device has been designed to operate safely in accordance with the current technical and
safety regulations of the EU. If installed incorrectly or used for applications for which it is not
intended, it is possible that application related changes may arise. For this reason, the instrument
must be installed, connected, operated, and maintained according to the instructions in this and
the specific product operating manual.
Persons handling/installing or commissioning this equipment must be authorized and suitably
qualified. The manual must be read, understood, and the instructions must be followed.
Modifications and repairs to the device are only permissible when they are expressly approved in
this manual.

Electrical Installation
ATTENTION: Substitution of components may impair intrinsic
safety.
Installation of the sensors must be carried out according to the instructions and diagrams in this section.
Sensors installed in this manner will become part of an intrinsically safe system that will be incapable of
igniting explosive gas atmospheres as specified on the sensor label and additional specifications in the
preceding section
There are four basic considerations that govern the electrical installation of the sensor. They are:
•
Cabling
o
Selection of a suitable cable
o
Wiring of the cable to a suitable sensor-side connector
o
Wiring of the cable to the Zener diode barrier(s) associated with the system.
