Publication 1794-IN093E-EN-P - August 2018
WARNING: Special Conditions for Safe Use:
• This equipment is not resistant to sunlight or other sources of UV radiation.
• This equipment shall be mounted in an ATEX/IECEx Zone 2 certified
enclosure with a minimum ingress protection rating of at least IP54 (in
accordance with EN/IEC 60079-15) 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.
• This equipment shall be used within its specified ratings defined by
Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being exceeded
by transient disturbances of more than 140% of the peak rated voltage
when applied in Zone 2 environments.
• The instructions in the user manual shall be observed.
• This equipment must be used only with ATEX certified Rockwell
Automation backplanes.
• Earthing is accomplished through mounting of modules on rail.
• Devices shall be used in an environment of not more than Pollution
Degree 2.
WARNING: Secure any external connections that mate to this equipment by
using screws, sliding latches, threaded connectors, or other means provided
with this product.
WARNING: Do not disconnect equipment unless power has been removed or
the area is known to be nonhazardous.
WARNING: When you insert or remove the module while backplane power is
on, an electric arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electric arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that
can affect module operation.
