Installation Guidelines
When determining where to place the switch, observe these guidelines:
• Airflow around the switch is unrestricted. To prevent the switch from
overheating, observe the following minimum clearances:
– Top and bottom: 50.8 mm (2.0 in.)
– Sides: 50.8 mm (2.0 in.)
– Front: 50.8 mm (2.0 in.)
European Hazardous Location Approval
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.
ATTENTION: This equipment is not resistant to sunlight or other sources of UV radiation.
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.
• 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: If you connect or disconnect Ethernet cables 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.
ATTENTION: The alarm port cables are not to exceed 10.0 m (32.81 ft).
