Installation Instructions

POINT I/O

Use this document to install and wire the following components of your POINT™ I/O system:

Interface: 1734-ADN, -PDN Bases: 1734-TB, -TBS, -TB3, -TB3S

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

(RTB usage covered)

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.

ATTENTION

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.

IMPORTANT

The 1734-FPD installs onto a DeviceNet network using the same steps as the 1734-PDN communication interface with one additional step included.

The 1734-FPD looks like the 1734-PDN but has no indicators.

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.

Interlocking Side Pieces

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.

ATTENTION

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.

Wiring Base

Do not pull on the installed wiring to remove a terminal block. A shock hazard exists if power is applied to the terminal block.

-OE2C, -OW2, -OB2E, -OB4E, -VHSC24, -VHSC5

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.

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.
