ATEX - Special conditions (extended temperature
range)
WARNING
Observe the special conditions for the intended use of Beckhoff fieldbus
components with extended temperature range (ET) in potentially explosive
areas (directive 94/9/EU)!
• The certified components are to be installed in a suitable housing that guarantees a
protection class of at least IP54 in accordance with EN 60529! The environmental con-
ditions during use are thereby to be taken into account!
• 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 tempera-
ture values!
• Observe the permissible ambient temperature range of -25 to 60°C for the use of Beck-
hoff fieldbus components with extended temperature range (ET) 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 terminals may only be unplugged or removed from the Bus Terminal sys-
tem if the supply voltage has been switched off or if a non-explosive atmosphere is en-
sured!
• 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!
• The fuses of the KL92xx/EL92xx power feed terminals may only be exchanged 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!
Standards
The fundamental health and safety requirements are fulfilled by compliance with the following standards:
• EN 60079-0:2012+A11:2013
• EN 60079-15:2010
Marking
The Beckhoff fieldbus components with extended temperature range (ET) certified for potentially explosive
areas bear the following marking:
II 3G KEMA 10ATEX0075 X Ex nA IIC T4 Gc Ta: -25 … 60°C
or
II 3G KEMA 10ATEX0075 X Ex nC IIC T4 Gc Ta: -25 … 60°C
