ATEX/IECEx SPECIAL CONDITIONS FOR SAFE USE
The following conditions relate to safe installation and/or use of the equipment.
• The permitted ambient temperature range for the LI24 is -40°C to 70°C.
• The equipment must be installed in an enclosure which provides a minimum degree of protection of
IP20 for the equipment connections.
• Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this
equipment may generate an ignition-capable level of electrostatic charge. Therefore, the equipment
shall not be installed in a location where the external conditions are conducive to the build-up of
electrostatic charge on such surfaces. This is particularly important if the equipment is installed in a
zone 0 location. In addition, the equipment shall only be cleaned with a damp cloth.
• The equipment loop/power port must be connected to an intrinsically safe barrier with Uo ≥ 11V.
• Entity parameters must meet the following requirements:
U
i: 30 V; Ii: 175 mA; Ci: 0 μF; Li: 0 μH; Pi: 1.0 W
• For ATEX Certification, barrier and transmitter must be ATEX Certified with Entity Parameters and must
be connected per manufacturer’s instructions.
FOR EUROPEAN COMMUNITY:
The LI24 must be installed in accordance with the Essential Health & Safety Requirements of Directive
2014/34/EU, the product certificates CML 17ATEX2015X and IECEx CML 17.0008X, and the product manual.
UL/C-UL SPECIAL CONDITIONS FOR SAFE USE
• Associated apparatus may be in a Division 2 or Zone location if so approved.
• Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this
equipment may generate an ignition-capable level of electrostatic charge. Therefore the equipment
shall not be installed in a location where the external conditions are conducive to the build-up of
electrostatic charge on such surfaces. This is particularly important if the equipment is installed in a
zone 0 location. In addition, the equipment shall only be cleaned with a damp cloth.
• The equipment shall be installed in a tool secured enclosure which provides a minimum degree of
protection of IP20 for the equipment connections.
• Entity parameters must meet the following requirements:
U
i: 30 V; Ii: 175 mA; Ci: 0 μF; Li: 0 μH; Pi: 1.0 W

FOR NORTH AMERICAN COMMUNITY:
Installation and service of this device and/or associated apparatus (barrier) should be performed only by
trained service personnel and must be installed in accordance with the manufacturer’s control drawing, Article
504 of the National Electric Code (ANSI/NFPA 70) for installation in the United States, or Section 18 of the
Canadian Electrical Code for installations in Canada.
