Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment. The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams. No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual. Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited. Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

ATTENTION

Environment and Enclosure

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 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 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.

See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional installation requirements pertaining to this equipment.

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated, yellow-chromated steel DIN rail to assure proper grounding. Using other DIN rail materials (for example, aluminum or plastic) which can corrode, oxidize, or are poor conductors can result in improper or intermittent platform grounding.

ATTENTION

Preventing Electrostatic Discharge

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.

Before You Begin

About the ac Expansion Power Supply

1734-EPAC Power Supply

Removable Terminal Block (RTB)

RTB Removal Handle

DIN-rail Locking Screw

Module Label

Interlocking Side Pieces

The 1734-EPAC ac expansion power supply passes 120/240V ac field power to the I/O modules to the right of it. This unit extends the backplane bus power for up to 17 I/O modules to the right of the supply, and creates a new field-voltage partition segment for driving field devices. The number of I/O modules supported by this power supply depend on the current required for each module and the DIN-rail mounting position. Do not exceed the current draw as shown in the specifications.

The ac expansion power supply also separates field power from I/O modules to the left of the unit, effectively providing functional and logical partitioning for:

POINT I/O 120/240V ac Expansion Power Supply 5

• separating field power between input and output modules.

• grouping modules to perform a specific task or function.

ATTENTION

WARNING

You can use multiple ac expansion power supplies with POINT I/O adapters to assemble a full system. For instance, if you are using the 1734-ADN adapter, you may use an ac expansion power supply to add additional modules in 4 to 17 module increments. For example, if you had a 36 module system with a 1734 POINT I/O adapter, you would have two 1734-EPAC ac expansion power supplies to provide more PointBus current for modules to the right of the supply.

You can only use the 1734-EPAC ac expansion power supplies with the 1734 POINT I/O adapters, such as the 1734-ADN, 1734-ADNX, 1734-APB, 1734-ACNR, and 1734-AENT adapters. Do not use with the 1734-PDN module or with POINTBlock modules.

Install the ac Expansion Power Supply

To install the power supply on the DIN rail, proceed as follows.

1. Position the power supply vertically above the DIN rail.

2. Engage the interlocking side pieces with the unit on the left.

3. Press down firmly to install the power supply on the DIN rail.

The locking mechanism will lock the power supply to the DIN rail.

Remove an ac Expansion Power Supply from the DIN Rail

1. To remove ac expansion power supply from the DIN rail, pull up on the RTB removal handle to remove the terminal block.

When you insert or remove the power supply while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the power supply and its mating connector. Worn contacts may create electrical resistance that can affect power supply operation.

WARNING

When you connect or disconnect the removable terminal block (RTB) with field-side power applied, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

2. Remove the module to the right of the power supply from its base unit.

3. Use a small-bladed screwdriver to rotate the DIN-rail locking screw to a vertical position.

This releases the locking mechanism.

4. Lift straight up to remove.

Replace an ac Expansion Power Supply

1. Remove the module to the right of the ac expansion power supply from its base unit.

2. Position the ac expansion power supply vertically above the DIN rail.

3. Slide the power supply down allowing the interlocking side pieces to

engage the adjacent modules (both left and right sides).

4. Press firmly to seat the power supply on the DIN rail.

The power supply locking mechanism will snap into place.

5. Reinsert the module into the base to the right of the power supply.
