10.1 Basic safety instructions
WARNING
Impermissible repair of explosion protected devices
Danger of explosion in areas subject to explosion hazard.
•
Repair must be carried out by Siemens authorized personnel only.
WARNING
Impermissible accessories and spare parts
Danger of explosion in areas subject to explosion hazard.
•
Only use original accessories or original spare parts.
• Observe all relevant installation and safety instructions described in the instructions for
the device or enclosed with the accessory or spare part.
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.
