Important User Information

Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application, Installation and
Maintenance of Solid State Controls (Publication SGI-1.1 available from your local
Rockwell Automation sales office or online at http://www.ab.com/manuals/gi)
describes some important differences between solid state equipment and hard-wired
electromechanical devices. Because of this difference, and also because of the wide
variety of uses for solid state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment
is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or
consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with any
particular installation, Rockwell Automation, Inc. cannot assume responsibility or
liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of
information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written
permission of Rockwell Automation, Inc. is prohibited.

Throughout this manual we use notes to make you aware of safety considerations.

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.

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

Publication 1734-IN052D-EN-E - February 2005

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

ATTENTION

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.

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.

5. 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.

WARNING

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.

Publication 1734-IN052D-EN-E - February 2005

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. Repeated electrical
arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may
create electrical resistance that can affect module
operation.

POINT I/O Source Input Module 7

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.

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.

WARNING

3. If an I/O module is installed, snap the RTB handle into place on the
module.

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. Repeated electrical
arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may
create electrical resistance that can affect module
operation.

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.

WARNING

3. Press on the module lock on the top of the module.

4. Pull on the I/O module to remove from the base.

WARNING

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.

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.

When you insert or remove the module while
backplane power is on, or you connect or disconnect
the RTB with field side power applied, an electrical arc
can occur. This could cause an explosion in hazardous
location installations. Be sure power is removed or the
area is nonhazardous before proceeding.
