Special conditions of use for ELX terminals
WARNING
Observe the special conditions of use for the intended use of Beckhoff ELX terminals in
potentially explosive areas (ATEX directive 2014/34/EU)!
• The certified components are to be installed in a suitable housing that guarantees an ingress protection
of at least IP54 in accordance with EN 60079-0 and EN 60529! The prescribed environmental conditions
during installation, operation and maintenance are thereby to be taken into account! Inside the housing,
pollution degree 1 and 2 are permissible.
• 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 of Beckhoff ELX terminals!
• Measures must be taken to protect against the rated operating voltage being exceeded by more than
40% due to short-term interference voltages! The power supply of the ELX9560 power supply terminal
must correspond to overvoltage category II according to EN 60664-1
• The individual terminals may only be unplugged or removed from the bus terminal system if all supply
voltages have been switched off or if a non-explosive atmosphere is ensured!
• The connections of the ELX9560 power supply terminal may only be connected or disconnected if all
supply voltages have been switched off or if a non-explosive atmosphere is ensured!
• The fuses of the EL92xx power feed terminals may only be exchanged if all supply voltages have been
switched off or if a non-explosive atmosphere is ensured!
• Address selectors and switches may only be adjusted if all supply voltages have been switched off or if a
non-explosive atmosphere is ensured!

Installation notes for ELX terminals
NOTE
Storage, transport and mounting
• Transport and storage are permitted only in the original packaging!
• Store in a dry place, free from vibrations.
• A brand new ELX terminal with a certified build version is delivered only in a sealed carton. Therefore,
check that the carton and all seals are intact before unpacking.
• Do not use the ELX terminal if
- its packaging is damaged
- the terminal is visibly damaged or
- you cannot be sure of the origin of the terminal.
• ELX terminals with a damaged packaging seal are regarded as used.
WARNING
Observe the accident prevention regulations
During mounting, commissioning, operation and maintenance, adhere to the safety regulations, accident
prevention regulations and general technical rules applicable to your devices, machines and plants.
CAUTION
Observe the erection regulations
Observe the applicable erection regulations.
