2.12 Inspection, maintenance and repair
The operator of an electrical system in a potentially explosive environment must keep
the equipment in a good condition, operate it properly, monitor it and maintenance and
repair work must be performed, also see EN/IEC 60079-17 in this respect.
Maintenance work and defect repairs may only be performed by trained professionals.
Before the maintenance or repair, the specified safety precautions are to be observed.
The warning notes on the equipment and in the other applicable documents are to be
adhered to!
The applicable laws and directives are complied with before recommissioning.
The existing thread pitches must be protected. They may not be subsequently modi-
fied or painted.
The replacement of defective parts of the flameproof enclosure and also the connec-
tion cap may only be performed by the manufacturer. Interchangeable components
such as the O-Ring for the connection cap and fastening screws shall be requested as
original part in the event of absence or damage, see chapter 9.4 on page 46.
The equipment does not require any maintenance by the operator. Nevertheless,
inspections must be performed at regular intervals:
Visual inspection
-
of the O-Ring in the connection cap for wear and tear
(whenever the connection cap is opened)
-
of the flameproof enclosure for damages
-
of the cables for external damages
-
for dust deposits
Checking of the cable entries for a tight fit
In case of damages, the equipment is to be taken out of service immediately and
to be repaired by the manufacturer!
The general instructions for repairs are to be adhered to, see the chapter
" Special conditions for safe use, marking "X" " on page 18.
