Installation Instructions
POINT I/O
Use this document to install and wire the following components of your POINT
™
I/O system:
POINT I/O modules have no switches to set. You set module parameters with a software configuration tool. To obtain EDS files for use in 
configuration, go to: http://www.ab.com/networks/eds
This product installation information is also available at: http://www.ab.com/manuals/io/
Installing the POINT I/O Adapter or 
Communication Interface
The 1734-ADN DeviceNet adapter and 
1734-PDN communication interface install 
onto a DeviceNet network.
1. Position the interface above the DIN rail.
2. Press down firmly to install the interface 
on the DIN rail.
3. The locking mechanism will lock the
interface to the DIN rail.
4. Remove safety end cap. Slide it up to
expose backplane and power connections.
If installing a replacement interface to an 
existing system:
1. Position the interface above the DIN rail.
2. Slide the interface down allowing the 
interlocking side pieces to engage the 
adjacent module.
3. Press firmly to seat the interface on the
DIN rail. The interface locking mechanism 
will snap into place.
4. To remove the interface from the DIN rail,
pull up on the RTB removal handle to 
remove the terminal block.
5. Use a small bladed screwdriver to rotate
the DIN rail locking screw to a vertical 
position.
6. This releases the locking mechanism.
Then lift straight up to remove.
Installing the Field Potential Dist.
The 1734-FPD installs onto a DeviceNet 
network using the same steps as the 
1734-PDN communication interface with one 
additional step included.
After positioning the 1734-FPD above the 
DIN rail, engage the interlocking side pieces 
with the unit on the left.
Installing the POINT I/O Wiring Base
The wiring base consists of a base and a 
removable terminal block (RTB). The 
1734-TB uses screw-clamp terminations; the 
1734-TBS uses spring-clamp terminations.
Installing the Wiring Base
1. Position wiring base vertically above
installed units (interface, power supply or 
existing module.
2. Slide the wiring base down allowing the
interlocking side pieces to engage the 
adjacent module or interface.
3. Press firmly to seat the wiring base on the
DIN rail. The wiring base will snap into 
place.
4. To remove the wiring 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 Removable Terminal Block
A removable terminal block is supplied with 
your terminal base. To remove, pull up on 
the RTB removal handle. 
This allows the base to be removed and 
replaced as necessary without removing any 
of the wiring. To reinsert the removable 
terminal block:
1. Insert the end opposite the handle into the 
base unit. This end has a curved section 
that engages 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.
4. Insert module straight down into wiring
base and press to secure. Module locks 
into place.
Removing a Wiring Base
To remove a wiring base, you must remove 
any installed module, and remove the 
removable terminal block (if wired). Then 
follow these steps:
1. Remove the RTB (if wired).
2. Turn the wiring base locking screw to a 
vertical position to unlock the base from 
the DIN rail.
3. Slide base up to release it from its mating
units.
Installing the I/O Module
The module can be installed before, or after 
base installation. Make sure that the wiring 
base is correctly keyed before installing the 
module into the wiring base. In addition, 
make sure the wiring base locking screw is 
positioned horizontal according to the base.
1. Using a bladed screwdriver, rotate the 
keyswitch on the wiring base clockwise to 
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
wiring base and press to secure. The 
module will lock into place.

ATTENTION
!
Do not discard end cap. Use 
end cap to cover exposed 
connections on the last terminal 
base in the chassis. Failure to 
do so could result in injury or 
equipment damage.
IMPORTANT
The 1734-FPD looks 
like the 1734-PDN but 
has no indicators.
