WARNING
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.
Exception: Devices having the type of protection "Intrinsic safety Ex i" may also be opened in energized state in hazardous
areas.
WARNING
Risk of explosion when media above 100 °C flows through the process flange
Explosion protection is no longer guaranteed and the approval is nullified.
It is prohibited for media above 100 °C to continually flow through the process flange.
Note
Hot surfaces
Hot process medium and high ambient temperatures lead to hot surfaces which can cause burns.
Take corresponding protective measures, for example wear protective gloves.

5.2
Introduction to commissioning
Following commissioning, the pressure transmitter is immediately ready for use.
To obtain stable measured values, the pressure transmitter needs to be allowed to warm up for five minutes or so after the
power supply is switched on.
The operating data must correspond to the values specified on the nameplate. If you switch on the auxiliary power, the
pressure transmitter will operate.
The following commissioning cases are typical examples. Configurations different from those listed here may be meaningful
depending on the system configuration.

Safety notes for commissioning with differential pressure and flow rate
WARNING
Incorrect or improper operation
If the lock screws are missing or are not sufficiently tight, and/or if the valves are operated incorrectly or improperly, it could
lead to serious physical injuries or considerable damage to property.
Measure
Make sure the locking screw and/or the vent valve are screwed in and tightened.
•
Ensure that the valves are operated correctly and properly.
