• 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
and should only be repaired by the manufacturer.
