ATEX/UKEX - Special conditions

WARNING

Observe the special conditions for the intended use of EtherCAT Box modules in potentially explosive areas!

  • The certified components are to be installed in a BG2000-0000 protection enclosure that guarantees a protection against mechanical hazards!
  • Provisions shall be made to prevent the rated voltage from being exceeded by transient disturbances of more than 119 V!
  • If the temperatures during rated operation are higher than 70°C at the feed-in points of cables, lines or pipes, or higher than 80°C at the wire branching points, then cables must be selected whose temperature data correspond to the actual measured temperature values!
  • Observe the permissible ambient temperature range of 0 … +55°C for the use of EtherCAT Box modules in potentially explosive areas!
  • Measures must be taken to protect against the rated operating voltage being exceeded by more than 40% due to short-term interference voltages!
  • The individual components may only be unplugged or removed from the bus system if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!
  • The connections of the certified components may only be connected or disconnected if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!
  • Address selectors and ID switches may only be adjusted if the supply voltage has been switched off or if a non-explosive atmosphere is ensured!
  • Only for connection to connection sets providing a degree of protection not less than IP54 in accordance with IEC 60079-0!
  • To avoid an electrostatic charge, wipe the enclosure surface with a damp cloth only.
  • The equipment shall only be used in an environment where it is protected against exposure to UV light.
  • For use in Zone 2/22 the equipment shall be installed in a suitable protective housing that meets the requirements of the impact resistance test according to EN IEC 60079-0.
  • When used in an area requiring the use of equipment with EPL Gc, the following additional conditions apply:
  • The equipment shall only be used in an area of not more than pollution degree 2, as defined in EN 60664-1.
  • Provisions shall be made to prevent the rated voltages from being exceeded by transient disturbances of more than 40%.
  • Fieldbus connectors may only be disconnected or connected when the system supply is switched off, or when the location is known to be non-hazardous.
  • Address selectors and ID switches may only be adjusted when the system supply is switched off, or when the location is known to be non-hazardous.

Standards

The fundamental health and safety requirements are fulfilled by compliance with the following standards:
