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:

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.
