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 tests are required in order to maintain the proper
condition.
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 piping connections for leakage.
• Checking the measuring unit and the indicator for dust deposits.
Following any maintenance work on the converter, re-grease the cover thread including the
cover seals with a non resinous, acid-free, all purpose grease.
