2.3 Use in hazardous areas
Qualified personnel for hazardous area applications
Persons who install, connect, commission, operate, and service the device in a hazardous
area must have the following specific qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures,
aggressive, and hazardous media.
● They are authorized, trained, or instructed in carrying out work on electrical circuits for

WARNING
Loss of the safety of the device with type of protection "Intrinsic safety Ex i"
If the device has already been operated in non-intrinsically safe circuits or the information
on the electrical specifications have been ignored, the safety of the device is no longer
ensured for use in hazardous areas. There is a danger of explosion.
•
Connect the device in Intrinsic Safety type of protection solely to an intrinsically safe
circuit.
•
Observe the information on the electrical specifications in the certificate and in the
"Technical specifications" chapter in the operating instructions.
WARNING
Use of incorrect device parts in potentially explosive environments
Devices and their associated device parts are either approved for different types of
protection or they do not have explosion protection. There is a danger of explosion if device
parts (such as covers) are used for devices with explosion protection that are not expressly
suited for this type of protection. If you do not adhere to these guidelines, the test
certificates and the manufacturer warranty will become null and void.
• Use only device parts that have been approved for the respective type of protection in
the potentially explosive environment. Covers that are not suited for the "explosion-
proof" type of protection are identified as such by a notice label attached to the inside of
the cover with "Not Ex d Not SIL".
• Do not swap device parts unless the manufacturer specifically ensures compatibility of
these parts.
