Publication 1769-IN063A-EN-P - March 2003
Environment and Enclosure
Prevent Electrostatic Discharge
ATTENTION
!
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring electromagnetic compatibility
in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as “open type” equipment. It must be mounted
within an enclosure that is suitably designed for those specific
environmental conditions 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.
Subsequent sections of this publication may contain additional information
regarding specific enclosure type ratings that are required to comply with
certain product safety certifications.
See NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the 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.
ATTENTION
!
Electrostatic discharge can damage integrated circuits or semiconductors if
you touch bus 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 bus 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 box.
