4.3 Operation in potentially explosive atmospheres (ATEX)
4.3.1 Special conditions
WARNING
Observe the special conditions for the intended use of Beckhoff fieldbus
components in potentially explosive areas (directive 94/9/EU)!
The certified components are to be installed in a suitable housing that guarantees a protec-
tion class of at least IP54 in accordance with EN 60529! The environmental conditions dur-
ing 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 ca-
bles, 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 to 55 °C when using Beckhoff
fieldbus components in potentially explosive atmospheres!
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 voltage has been switched off or if a non-explosive atmosphere is ensured!
The fuses of the 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!
The fundamental health and safety requirements are fulfilled by compliance with the following standards:
• EN 60079-0: 2006
• EN 60079-15: 2005
