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.
