3.5 ATEX Notes
3.5.1 ATEX ­ Special conditions
WARNING
Observe the special conditions for the intended use of EtherCAT Box mod­
ules in potentially explosive areas – directive 94/9/EU.
• The certified components are to be installed in the BG2000‐0000 protection enclosure
[ } 47] that guarantees a protection against mechanical hazards!
• If the temperatures during rated operation are higher than 70°C at the feed­in 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 tempera­
ture values!
• Observethe 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 short­term interference voltages!
• The connections of the certified components may only be connected or disconnected if
the supply voltage has been switched off or if a non­explosive atmosphere is ensured!
Standards
The fundamental health and safety requirements are fulfilled by compliance with the following standards:
• EN 60079­0: 2006
• EN 60079­15: 2005
