1.16 Maintenance and inspection safety information

Warning – Risk to persons!
When the housing cover is open, EMC and protection against contact are suspended. There
are electric circuits within the housing which pose a contact risk.
The auxiliary power must be switched off before opening the housing cover.
Warning – Risk to persons!
The inspection screw (for draining condensate fluid) for devices ≥ DN 350 can be under
pressure. The medium which spurts out can cause severe injuries.
Depressurize pipes before opening the inspection screw.
Corrective maintenance work may only be performed by trained personnel.
• Depressurize the device and adjoining lines or containers before removing the device.
• Check whether hazardous materials are used as materials to be measured before opening
the device. Residual amounts of hazardous material may still be present in the device and
could escape when the device is opened.
• As far as provided in the scope of the operational responsibility, check the following items
through a regular inspection:
− the pressure-carrying walls / lining of the pressure device
− the measurement-related function
− the leak tightness
− the wear (corrosion)
