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.
WARNING
Maintenance during continued operation in a hazardous area
There is a danger of explosion when carrying out repairs and maintenance on the device in a hazardous area.
● Isolate the device from power.
- or -
● Ensure that the atmosphere is explosion-free (hot work permit).
WARNING
Commissioning and operation with pending error
If an error message appears, correct operation in the process is no longer guaranteed.
● Check the gravity of the error
● Correct the error
● If the error still exists:
– Take the device out of operation.
– Prevent renewed commissioning.
WARNING
Hot, toxic or corrosive process media
Danger of injury during maintenance work.
When working on the process connection, hot, toxic or corrosive process media could be released.
● As long as the device is under pressure, do not loosen process connections and do not remove any parts that are
pressurized.
● Before opening or removing the device ensure that process media cannot be released.
WARNING
Improper connection after maintenance
Danger of explosion in areas subject to explosion hazard.
● Connect the device correctly after maintenance.
● Close the device after maintenance work.
Refer to Chapter "Connecting the device (Page 17)".
WARNING
Use of a computer in a hazardous area
If the interface to the computer is used in the hazardous area, there is a danger of explosion.
● Ensure that the atmosphere is explosion-free (hot work permit).
