Chapter 2 Installation Instructions
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 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not provide adequate protection to radio
communication services in such environments.
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 enclosure must have suitable flame-retardant properties to prevent or minimize the spread
of flame, complying with a flame spread rating of 5VA or be approved for the application if non-metallic. 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1 , for additional installation requirements
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures
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 wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
ATTENTION: Do not insert or remove a module, base unit or termination assembly while power is applied. Interruption of
the backplane can result in unintentional operation or machine motion.
ATTENTION: For UL approved installations, the 1715-OB8DE output power source must be isolating, wired with a minimum
of 0.75 mm
2 (18 AWG) wire and fused with a rating of 32V DC min/5 A max.
ATTENTION: Do not wire more than 1 conductor on any single terminal.
ATTENTION: This equipment is not resistant to sunlight or other sources of UV radiation.
