4.9 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2014/34/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60079-15! The environmental conditions during use are thereby to be
taken into account!
• For dust (only the fieldbus components of certificate no. KEMA10ATEX0075XIssue9): The equipment
shall be installed in a suitable enclosure providing a degree of protection of IP54 according to
EN60079-31 for group IIIA or IIIB and IP6X for group IIIC, taking into account the environmental condi-
tions under which the equipment is used!
• 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 tempera-
ture data correspond to the actual measured temperature values!
• Observe the permissible ambient temperature range of -25 to 60°C for the use of Beckhoff fieldbus com-
ponents 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 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 volt-
age 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
• EN 60079-31:2013 (only for certificate no. KEMA 10ATEX0075 X Issue 9)
