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://literature.rockwellautomation.com) 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.

WARNING
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.
About the Modules
The POINT I/O Common Terminal Module and Voltage Terminal
Module provide expansion of the termination capability of POINT
I/O. The modules support higher density (8 channel) POINT I/O
modules and management of wiring of field devices to the POINT
I/O solution.

Install 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 so that 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 snaps into place.
Install the Module
Install the module before or after mounting base installation. Be sure
to correctly key the mounting base before installing the module into
the mounting base. In addition, be sure to position the mounting
base locking screw horizontal referenced to the base.
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. 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.
1. Using a bladed screwdriver, rotate the keyswitch on the
mounting base clockwise until the number required for the
type of module you are installing 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 locks into place.
Install the Removable Terminal Block (RTB)
You will find the RTB supplied with the wiring base assembly. To
remove, pull up on the RTB handle. You can now remove the
mounting base and replace as necessary without removing any of the
wiring. To reinsert the RTB, 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.

Remove a Mounting Base
To remove a mounting base, y ou 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.
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. 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.
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. Lift straight up to remove.
