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.

WARNING
!
EXPLOSION HAZARD
• Do not disconnect equipment unless power has
been removed or the area is known to be
nonhazardous.
• Do not disconnect connections to this equipment
unless power has been removed or the area is
known to be nonhazardous. Secure any external
connections that mate to this equipment by using
screws, sliding latches, threaded connectors, or other
means provided with this product.
• Substitution of components may impair suitability for
Class I, Division 2.
• If this product contains batteries, they must only be
changed in an area known to be nonhazardous.
Installing the Mounting Base
To install the mounting base on the DIN rail, proceed as follows.
1. Position the mounting base vertically above the installed units
(adapter, power supply or existing module.
2. Slide the mounting base down allowing the interlocking side
pieces to engage the adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The
mounting base will snap into place.
4. To remove the mounting base from the DIN rail, remove the
module, and use a small bladed screwdriver to rotate the base
locking screw to a vertical position. This releases the locking
mechanism. Then lift straight up to remove.
Installing the I/O Module
The module can be installed before, or after base installation. Make
sure that the mounting base is correctly keyed before installing the

module into the mounting base. In addition, make sure the mounting
base locking screw is positioned horizontal referenced to the base.
1. Using a bladed screwdriver, rotate the keyswitch (2) on the
mounting base clockwise until the number required for the
type of module being installed aligns with the notch in the
base.
2. Make certain the DIN rail locking screw is in the horizontal
position. (You cannot insert the module if the locking
mechanism is unlocked.)
3. Insert the module straight down into the mounting base and
press to secure. The module will lock into place.
When you insert or remove the module while
backplane power is on, an electrical arc can
occur. This could cause an explosion in
hazardous location installations. Be sure that
power is removed or the area is nonhazardous
before proceeding.
