Maintenance plan
▸
Use original SICK spare parts only.
For devices used in potentially explosive atmospheres:
▸
Maintenance and inspection should only be carried out by experienced/trained
personnel with knowledge of the rules and regulations for potentially explosive
atmospheres, especially:
– Ignition protection types
– Installation regulations
– Range specification
▸
Standards to be applied (examples):
– IEC 60079-14, Annex F: Knowledge, skills and competencies of responsible
persons, operatives and designers.
– IEC 60079-17: Electrical installations inspection and maintenance
– IEC 60079-19: Device repair, overhaul and reclamation
