IEC Hazardous Location Approval
Enclosure
The 1719 Ex I/O distributed I/O is specially designed for operation within an enclosure or within a monitored environment. Observe the requirements for enclosures and the
installation conditions set out in the chapter on safety of the 1719 Ex I/O User Manual, publication 1719-UM001.
The following applies to products with IECEx certification. Such modules:
• Are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air are unlikely to occur, or are likely to occur only infrequently and
for short periods. Such locations correspond to Zone 2 classification to IEC 60079-0.

ATTENTION: This equipment is not resistant to sunlight or other sources of UV radiation.
WARNING:
• This equipment shall be mounted in an ATEX/IECEx Zone 2 certified enclosure with a minimum ingress protection rating of at least IP54 (as defined in
EN/IEC 60529) and used in an environment of not more than Pollution Degree 2 (as defined in EN/IEC 60664-1) when applied in Zone 2 environments. The
enclosure must be accessible only by the use of a tool.
• Provision shall be made to prevent the rated voltage from being exceeded by transient disturbances of more than 140% of the rated voltage when
applied in Zone 2 environments.
• Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this
product.
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.
WARNING: Risk of explosion.
Electrostatic charging of plastic components can lead to discharge, which can cause explosive mixtures to ignite.
• Avoid electrostatic charges. For example, plastic parts must always be cleaned using a damp cloth, and never using a dry cloth.
• Affix a warning sign that is easily recognizable to the inside of the enclosure. The sign must read as follows: “WARNING — avoid electrostatic charge”.
