of authorised inspectors.
To maintain proper condition, regular inspections are required for systems in hazardous areas.
The following checks are recommended:
• Checking the housing, the cable entries and the feed lines for corrosion and/or damage.

• Checking the measuring unit and the indicator for dust deposits.
• Including the pressure transmitters in the regular pressure test of the process line.

Removal and installation are the responsibility of the operator.
Before disconnecting the electric connecting cable of the device, make sure that all cables
leading to the indication unit are isolated from the ground of the hazardous area. This also
applies to functional earthing conductors (FE) and equipotential bonding conductors (PA).
WARNING!
Pressurised pipes have to be depressurised before removing the measuring unit.
•
In the case of environmentally critical or hazardous products, appropriate safety precautions
•
must be taken with regard to residual liquids in the measuring unit.
