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:
•
Check the housing, connection terminals and feed lines for corrosion and/or damage.
Close the housing following any maintenance work on the electronic signal output.
6.2 Dismantling
Replacing the electronic signal output
Due to the modular design of the electronic signal output, from a safety perspective it is possible
to replace a module with an identical spare part.
Exchanging and dismantling should take place in a de-energised state, if at all possible. If this is
not possible, the basic conditions for intrinsic safety (e.g. no grounding or connection of different
intrinsically safe circuits to one another) must be observed during dismantling.
The dismantling and installation is within the responsibility of the operator.
CAUTION!
There may be a risk of losing measuring accuracy!
