The following applies when the product bears the Ex Marking.
This equipment is intended for use in potentially explosive atmospheres as defined by European Union Directive 94/9/EC and has been found to
comply with the Essential Health and Safety Requirements relating to the design and construction of Category 3 equipment intended for use in
Zone 2 potentially explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN 60079-15 and EN 60079-0.
WARNING:
• This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54
(as defined in IEC60529) and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1) when
applied in Zone 2 environments. The enclosure must have a tool-removable cover or door.
• 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 rated voltage when applied in Zone 2 environments.
• This equipment must be used only with ATEX certified Rockwell Automation Termination Assemblies.
• 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.
• Enclosure must be marked with the following: ‘Warning - Do not open when energized.’ After installation of equipment
into the enclosure, access to termination compartments shall be dimensioned so that conductors can be readily connected.
WARNING: If you connect or disconnect the communication cable with power applied to this module or any device on the
network, an electrical 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.
WARNING: If you connect or disconnect wiring while the field-wire power is on, an electrical 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.
WARNING: If you insert or remove a base unit or termination assembly while power is applied, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed before proceeding.
WARNING: Do not remove or replace fuses when energized. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
