WARNING
Opening device in energized state
Risk of explosion in hazardous areas
● Only open the device in a de-energized state.
● Check prior to commissioning that the cover, cover locks, and cable inlets are assembled
in accordance with the directives.
Exception: Devices having the type of protection "Intrinsic safety Ex i" may also be opened in
energized state in hazardous areas.
WARNING
Water in compressed air line
Device damage and possibly loss of type of protection. The factory setting for the purging air
selector is "IN". In the "IN" position, water from the compressed air line may enter the device
from the pneumatics during initial commissioning.
● Before commissioning, make sure that no water is present in the compressed air line.
If you cannot be sure that there is no water in the compressed air line:
● Set the purging air selector to "OUT". In this way, you prevent water from the compressed
air line from penetrating the device.
● Only set the purging air selector to "IN" again when all water has been discharged from the
compressed air line.
WARNING
Loss of type of protection
Risk of explosion. Damage to device if the enclosure is open or not properly closed. The type
of protection specified on the nameplate or in Technical data (Page 281) is no longer
guaranteed.
● Make sure that the device is securely closed.
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.
