Environment and Enclosure

ATTENTION

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 (6562 ft) 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 enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. 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.

In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley

publication 1770-4.1

• NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by different types of enclosure

, for additional installation requirements.

4 POINT I/O Module with 8 Configurable 24V DC Points

Prevent Electrostatic Discharge

ATTENTION

This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment.

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in

use.

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated, yellow-chromate steel DIN rail to be sure of proper grounding. The use of other DIN rail materials, such as aluminum and plastic that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.87 in.) and use end-anchors appropriately.

To comply with the CE Low Voltage Directive (LVD), all connected I/O must be powered from a source compliant with the following: Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

About the Module

The 1734-8CFG module is a 24V DC I/O module with 8 self-configuring points. Each of the I/O points can be a DC input or output. The module supports removal and insertion under power, auto-address, and auto-baud in compliance with the POINTBus backplane.

Before You Begin

See the figures to familiarize yourself with major parts of the module, noting that the wiring base assembly is one of the following:

• 1734-TB or 1734-TBS POINT I/O two-piece terminal base, which

includes the 1734-RTB removable terminal block and 1734-MB mounting base

• 1734-TOP or 1734-TOPS POINT I/O one-piece terminal base

The 1734-8CFG module is not compatible with 1734-TB3, 1734-TB3S, 1734-TOP3, and 1734-TOP3S terminal bases.

Install the Mounting Base

Follow these steps to install the mounting base on the DIN rail.

1. Position the mounting base vertically above the installed units, for example, adapter, power supply, or existing module.

2. Slide the mounting base down so that the interlocking side pieces engage the adjacent module or adapter.

3. Press firmly to seat the mounting base on the DIN rail until the mounting base snaps into place.

4. To remove the mounting 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.
