Environment and Enclosure

This equipment is inte nded for use in a P ollut ion Degr ee 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meter without derating.

This equipment is s uppl ied as “ope n typ e” eq uipm ent. It must be mounted within an enclosure that is suitably designed for t hose speci fic enviro nmental cond itions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequen t sec tion s of th is public atio n may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC publications 60529, as a pplicable, for ex planatio ns of t he degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 (“Industrial Automation Wiring and Grounding Guidelines”), for additional installation requirements pertaining to this equipment.

Prevent Electrostatic Discharge

The scanner module is sensitive to electrostatic discharge.

ATTENTION

Electrostati c discharge can damag e int eg rated circuits or semiconductors if you touch backplane connector pins. Follow these guidelines when you handle the module:

• touch a grounded object to discharge static potential

• wear an approved wrist-strap grounding device

• do not touch the backplane connector or connector

pins

• do not touch circuit components inside the module

• if available, use a static-safe work station

• when not in use, keep the module in its static-shield

bag
