Repair
Ensure that only authorised and trained personnel perform repairs and maintenance
work on equipment that is placed into a hazardous area. The training has included
instruction on the various types of protection and installation practices, the relevant
rules and regulations and on the general principles of area classification.
Care must be taken to maintain the integrity of the type of protection provided for the

When necessary, the working area shall be confirmed gasfree prior to commencement
of any work. Maintenance and repairs must only be undertaken using original spare
parts and after prior consultation with Weidmüller.
Inspection
After opening an enclosure, a visual inspection of the lid gasket must be performed to
ensure no foreign objects may interfere with the enclosure sealing function.
A visual inspection of the apparatus shall be carried out appropriate to the installation
environment.
Inspection should include verification that all certification details are clearly legible and
that lid screws are secured to the correct torque. Checks should also include that there
is no ingress (dust or liquid) inside the enclosure and that all cable glands and main
earth connections are in good order. During each inspection, the enclosure should be
cleaned with a damp cloth. It is not allowed to clean the enclosure with hydrocarbon
based cleaning compounds!
