1 This product must be mounted within a suitable system enclosure to prevent personal injury resulting from
accessibility to live parts. The interior of this enclosure must be accessible only by the use of a tool. This
industrial control equipment is intended to operate in a Pollution Degree 2 environment, in overvoltage
category II applications, (as defined in IEC publication 664A) at altitudes up to 2000 meters without
derating.
2 Use this category information for planning conductor routing as described in publication 1770-4.1,
"Industrial Automation Wiring and Grounding Guidelines."
