Inspection, Maintenance and Repairs

WARNING
Disconnect power supply before installing or servicing these
enclosures.
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 enclosure; this may require
consultation with the manufacturer. 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 installed professionally and are in good
condition.
Make sure you are in compliance with the latest IEC 60079-17/
EN 60079- 17 and any other relevant national regulations that pertain to the
maintenance of electrical equipment in hazardous atmospheres. Working
with live voltages is not permitted without prior written approval from the
facility operator.
