ATTENTION: If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. ATTENTION: Read this document and the documents listed in the Additional Resources section about installation, configuration, and operation of this equipment before you install, configure, operate, or maintain this product. Users are required to familiarize themselves with installation and wiring instructions i n addition to requirements of all applicable codes, laws, and standards. ATTENTION: Installation, adjustments, putting into service, use, assembly, disassembly, and maintenance are required to be carried out by suitably trained personnel in acco rdance with applicable code of practice. In case of malfunction or damage, no attempts at repair sh ould be made. The module should be returned to the manufacturer for repair. Do not dismantle the module. ATTENTION: This equipment is certified for use only within the surrounding air temperature range of -20…+55 °C (-4…+131 °F). The equipment must not be used outside of this range. ATTENTION: Use only a soft dry anti-static cloth to wipe down equipment. Do not use any cleaning agents.

About the Assembly

The POINT I/O™ wiring base assembly consists of a mounting base (4) a nd a removable terminal block (RTB)(3). 1734-TB3 uses screw-clamp termination; 1734-TB3S uses spring-clamp terminations.

Install the Mounting Base

To install the mounting base on the DIN rail (Allen-Bradley part number 199-DR1; 4 6277-3; EN50022), proceed as follows.

ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in impropTer or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for more information.

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 t he DIN rail. The mounting base snaps into place.

Install the 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 that the mounting base locking screw is positioned horizontal referenced to the base.

Turn the keyswitch to align the number with the notch. Notch position 3 is shown.

Be sure the DIN rail locking screw is in the horizontal position.

1. Use a bladed screwdriver to 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. Verify 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 in to the mounting base and press to secure. The module locks into place.

Install the Removable Terminal Block

A Removable Terminal Block (RTB) 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 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.

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

WARNING: For 1734-RTBS and 1734-RTB3S, to latch and unlatch the wire, insert a bladed screwdriver (catalog number 1492-N90 – 3 mm diameter blade) into the opening at approximately 73° (blade surface is parallel with top surface o f the opening) and push up gently.

Remove 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.

ATTENTION: Do not remove or replace a Terminal Base unit while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.

WARNING: Do not disconnect or replace component unless power is switched off or area is known to be nonhazardous. Do not pull on the installed wiring to remove a terminal base. A shock hazard exists if power is applied to the terminal base.

1. Unlatch the RTB handle on the I/O module.

2. Pull on the RTB handle to remove the removable terminal block.

3. Press the module lock on the top of the module and pull on the I/O module to remove from the base.

4. Repeat steps 1…3 for the module to the right.

5. Use a small bladed screwdriver to rotate the orange base locking screw t o a vertical position. This releases the locking mechanism.

6. Lift the mounting base straight up to remove.
