5 Commissioning
5.1 Basic safety instructions
Improper commissioning in hazardous areas
Device failure or danger of explosion in hazardous areas.
• Do not commission the device until it has been mounted completely and connected in accordance with the information
in Chapter "Technical data (Page 38)".
•
Before commissioning take the effect on other devices in the system into account.
Loss of explosion protection
Danger of explosion in hazardous areas if the device is open or not properly closed.
•
Close the device as described in Chapter "Installing/mounting (Page 8)".
Opening device in energized state
Danger of explosion in areas subject to explosion hazard.
• 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.
: Devices having the type of protection "Intrinsic safety Ex i" may also be opened in energized state in hazardous
areas.
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.
Loss of degree of protection
Damage to device if the enclosure is open or not properly closed. The degree of protection specified on the nameplate or in
Chapter "Technical data (Page 38)" is no longer guaranteed.
•
Make sure that the device is securely closed.
