Servicing and Maintenance
The provisions of IEC 60079-17 'Inspection
and maintenance of electrical installations in
hazardous areas' relating to inspection, ser-
vicing and maintenance must be complied
with. In the course of inspections and main-
tenance work, those components on which
the type of explosion protection is dependent
must be inspected particularly carefully.

Qualifications
The inspection, servicing and maintenance of
the equipment may only be carried out by expe-
rienced personnel who during their training have
also been instructed in the various types of
explosion protection, installation processes, the
relevant rules and regulations and the general
principles of hazardous zone classification.
Appropriate ongoing training or instruction must
be given to these personnel regularly.
6.2
Requirements to be met by the
enclosure
Check the condition of the gaskets.
To ensure compliance with the permissible sur-
face temperatures, ensure that the ambient tem-
perature remains within the range indicated on
rating plate. In this connection, remember to take
the effects of other heat sources into account,
such as exposure to sunlight or, if applicable,
higher switching capacities for short periods.
These effects should not be allowed to raise the
enclosure temperature additionally.
