Environment and Enclosure
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
!
This equipment is sensitive to electrostatic discharge which can
cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
•
touch a grounded object to discharge potential static
•
wear an approved grounding wrist strap
•
do not touch connectors or pins on component boards
•
do not touch circuit components inside the equipment
•
if available, use a static-safe workstation
•
when not in use, store the equipment in appropriate
static-safe packaging
