into account including any special conditions defined
therein.
• The equipment shall only be used as intended.
• The equipment is only to be connected when de-
energized.
• The potential equalization of the system has to be
established according to the regulations of erection
applicable in the respective country of use (VDE 0100,
part 540; IEC 364-5-54). For installation according to the
North American Zone concept the external grounding is
supplementary.
• Circulating currents shall not be led via the enclosures!
• It has to be ensured that the enclosure is properly
installed and that its IP protection is not impaired.
• Inside the potentially explosive atmospheres' assembly
shall only be performed taking the locally applicable rules
of erection into account.
The following conditions have to be observed (incomplete):
• Assembly and maintenance to be done only if atmosphere
is Ex-free and a permit for hot works is in place.
• The TZIDC is only to be operated in a fully mounted and
intact enclosure.

Maintenance, repair
Maintenance: defines a combination of any actions carried out to
retain an item in, or restore it to, conditions in which it is able to
meet the requirements of the relevant specification and perform
its required functions.
Inspection:
defines any action comprising careful scrutiny of an item
carried out either without dismantling, or with the addition
of partial dismantling as required, supplemented by means
such as measurement, in order to arrive at reliable conclusion
as to the condition of an item.
Visual inspection:
defines an inspection which identifies, without the use of
access equipment and tools, those defects, such as missing
bolts, which will be apparent to the eye.
Close inspection:
defines an inspection which encompasses those aspects
covered by a visual inspection and, in addition, identifies
those defects, such as loose bolts, which will be apparent
only be the use of access equipment, for example steps,
where necessary, and tools.
Detailed inspection:
defines an inspection which encompasses those aspects
covered by a close inspection and, in addition, identifies
those defects, such as loose terminations, which will only be
apparent by opening the enclosure, and/or using, where
necessary, tools and test equipment.
• Maintenance or replacement works are to be carried out by
qualified personnel only, i.e. personnel qualified according to
TRBS 1203 or similar.
• Only such auxiliary components may be used in explosive
atmospheres which meet all requirements of European and
national directives and legislation.
• Maintenance works that require a dismantling of the system
shall only be performed if the atmosphere is Ex-free. If that is
not possible, however, the usual precautions have to be
ensured according to local regulations.
• Components shall only be replaced by original spare parts
which are therefore approved for the use in ex- plosive
atmospheres.
• Inside the Ex-atmosphere the equipment has to be cleaned
regularly. The intervals are to be defined by the user in
compliance with the environmental conditions present at the
place of operation.
• After maintenance and repair works have been performed, all
barriers and notes removed for that purpose have to be put
back in their original place.
• The flameproof joints differ from the tables of IEC 60079-1
