Intended use
WARNING
Endangering the safety of persons and equipment!
The ELX components may only be used for the purposes described below!
CAUTION
Observe ATEX and IECEx!
The ELX components may only be used in accordance with the ATEX directive and the IECEx scheme!
The ELX terminals extend the field of application of the Beckhoff bus terminal system with functions for
integrating intrinsically safe field devices from hazardous areas. The intended field of application is data
acquisition and control tasks in discrete and process engineering automation, taking into account explosion
protection requirements.
The ELX terminals are protected by the type of protection "Increased safety" (Ex e) according to
IEC 60079-7 and must only be operated in hazardous areas of Zone 2 or in non-hazardous areas.
The field interfaces of the ELX terminals achieve explosion protection through the type of protection "intrinsic
safety" (Ex i) according to IEC 60079-11. For this reason, only appropriately certified, intrinsically safe
devices may be connected to the ELX terminals. Observe the maximum permissible connection values for
voltages, currents and reactances. Any infringement can damage the ELX terminals and thus eliminate the
explosion protection.
The ELX terminals are open, electrical equipment for installation in lockable cabinets, enclosures or
operating rooms. Make sure that access to the equipment is only possible for authorized personnel.
CAUTION
Ensure traceability!
The buyer has to ensure the traceability of the device via the Beckhoff Traceability Number (BTN).
