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
!
POINT I/O is grounded through the DIN rail to
chassis ground. Use zinc plated, yellow chromated
steel DIN rail to assure proper grounding. Using
other DIN rail materials (e.g. aluminum, plastic,
etc.) which can corrode, oxidize or are poor
conductors can result in improper or intermittent
platform grounding.

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.
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.

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.)
WARNING
!
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.

3. Insert the module straight down into the mounting base and
press to secure. The module will lock into place.
Installing the Removable Terminal Block (RTB)
A removable terminal block is supplied with your wiring base
assembly. To remove, pull up on the RTB handle. This allows the
mounting base to be removed and replaced as necessary without
removing any of the wiring. To reinsert the removable terminal block,
proceed as follows.
1. Insert the end opposite the handle into the base unit. This end
has a curved section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks
itself in place.
3. If an I/O module is installed, snap the RTB handle into place
on the module.
WARNING
!
When you connect or disconnect the Removable
Terminal Block (RTB) with field side power
applied, 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.

Removing a Mounting Base
To remove a mounting base, you must remove any installed module, and the
module installed in the base to the right. Remove the removable terminal
block (if wired).
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the removable terminal block.
3. Press on the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3 and 4 for the module to the right.
6. Use a small bladed screwdriver to rotate the orange base locking
screw to a vertical position. This releases the locking mechanism.
7. Then lift straight up to remove.
WARNING
!
When you connect or disconnect the Removable
Terminal Block (RTB) with field side power
applied, 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.

Communicating with Your Module
I/O messages are sent to (consumed) and received from (produced)
the POINT I/O modules. These messages are mapped into the
processor’s memory. This POINT I/O output module produces 1 byte
of input data (scanner Rx) (status). It consumes 1 byte of I/O data
(scanner Tx).
