ATTENTION
!
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.
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.

Overview
Install your power supply using these installation instructions. The only tools you
require are Flat head (1/8”) and Phillips head (1/4”, #2) screwdrivers.
Hazardous Location Considerations
Products marked CL1, DIV 2, GP A, B, C, D are suitable for use in Class I, Division
2, Groups A, B, C, D or non-hazardous locations only. Each product is supplied
with markings on the rating nameplate indicating the hazardous location
temperature code. When combining products within a system, the most adverse
temperature code (lowest “T” number) may be used to help determine the overall
temperature code of the system. Combinations of equipment in your system are
subject to investigation by the local Authority Having Jurisdiction at the time of
installation.
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch backplane connector pins. Follow
these guidelines when you handle the power supplies.
•Touch a grounded object to discharge static potential.
•Do not touch the backplane connector or connector pins.
•Do not touch circuit components inside the power supply.
•If available, use a static-safe work station.
•When not in use, keep the power supplies in their
static-shield packaging.
IMPORTANT If the equipment is not installed and used as described in this
manual, the protection provided by the equipment may be
impaired.
WARNING
!
EXPLOSION HAZARD
•Do not disconnect equipment unless power has been
removed or the area is known to be non-hazardous.
•Do not disconnect connections to this equipment unless
power has been removed or the area is known to be
non-hazardous. Secure any external connections that mate
to this equipment using screws, sliding latches, threaded
connectors, or other means provided with this product.
•Substitution of components may impair suitability for Class
I, Division 2.
•All wiring must comply with N.E.C. article 501-4(b).
