IECEx - Special conditions

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 IEC 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.
