ArmorPOINT 24V DC Very High Speed Counter Modules, Series A 3
ATTENTION Environment and Enclosure
This equipment is intended for use 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 "enclosed" equipment. It
should not require additional system enclosure when used
in locations consistent with the enclosure type ratings
stated in the Specifications section of this publication.
Subsequent sections of this publication may contain
additional information regarding specific enclosure type
ratings, beyond what this product provides, that are
required to comply with certain product safety
certifications.
NOTE: 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 Preventing Electrostatic Discharge
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 wriststrap.
• 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.
