6.1 Maintenance
Maintenance work of a safety-relevant nature within the meaning of explosion protection may
only be carried out by the manufacturer, his authorised representative or under the supervision
of authorised inspectors.
For systems in hazardous areas, regular checks are required in order to maintain the proper
condition.
The following checks are recommended:
•
Check the housing, the cable entries and the feed lines for corrosion and/or damage.
Close the cover once maintenance work on the display and operating unit has been completed.
6.2 Dismantling
In order to prevent injury or material damage when replacing the display, always observe the
following points:
•
Before dismantling the electrical connecting lines of the device, ensure that all the cables
leading to the display are de-energised themselves and to the reference potential of the
explosive area.
