Risk of explosion.
• Only use equipment that is approved for use in the intended hazardous area and labeled

WARNING
Loss of safety of device with type of protection "Intrinsic safety Ex i"
If the device or its components have already been operated in non-intrinsically safe circuits or
the electrical speci󹪝cations have not been observed, the safety of the device is no longer
ensured for use in hazardous areas. There is a risk of explosion.
• Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe
circuit.
• Observe the speci󹪝cations for the electrical data on the certi󹪝cate and/or in Technical data
(Page 61).
WARNING
Use of incorrect device parts in potentially explosive environments
Devices and their associated device parts are either approved for di󹪜erent types of protection
or they do not have explosion protection. There is a risk 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 certi󹪝cates 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 identi󹪝ed 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 speci󹪝cally ensures compatibility of
these parts.
