Electrostatic Discharge

Compact High-density Analog Current Input Module 3

ATTENTION

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:

Remove Power

ATTENTION

Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

• Use a static-safe work station, if available.

• Keep the module in its static-shield box when not in use.

• sending an erroneous signal to your system’s field devices, causing

unintended machine motion.

• causing an explosion in a hazardous environment.

(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a

temporary conductivity caused by condensation is expected.

(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level, transient voltages are

controlled and do not exceed the impulse voltage capability of the product’s insulation.

(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

1. Add the module to the 1769 system.

You can add the module before or after mounting.

2. Mount Expansion I/O.

• Panel mount

• DIN-rail mount

3. Make field wiring connections.

4. Configure the module.

This publication describes these steps in detail.

Adding the Module to the 1769 System

Attach the module to the controller or an adjacent I/O module before or after mounting. For mounting instructions, see Use the Dimensional Template

the Module to a DIN Rail. To work with a system that is already mounted, see Replace a Single Module Within a System

, or Mount

Compact High-density Analog Current Input Module 7

Assemble the 1769 System

The following procedure shows you how to assemble the Compact I/O system.

1. Disconnect power.

2. Check that the bus lever of the module to be installed is in the unlocked (fully right) position.

3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together or to a controller.

4. Move the module back along the tongue-and-groove slots until the bus connectors (2) line up with each other.

5. Push the bus lever back slightly to clear the positioning tab (3).

Use your fingers or a small screwdriver.

6. To allow communication between the controller and module, move the bus lever fully to the left (4) until it clicks, making sure it is locked firmly in place.

ATTENTION

When attaching I/O modules, it is very important that the bus connectors

are securely locked together to be sure of proper electrical connection. Securely locking together the bus connectors is required for use in hazardous locations.

For more information on hazardous locations see page 4

7. Attach an end-cap terminator (5) to the last module in the system by using the tongue-and-groove slots as before.

8. Lock the end-cap bus terminator (6).

IMPORTANT

You must use a 1769-ECR or 1769-ECL right or left end cap to terminate the end of the serial communication bus. An I/O configuration fault will occur if an end cap is not used.

Replace a Single Module Within a System

The module can be replaced while the system is mounted to a panel or DIN rail.

1. Remove power.

See Remove Power

2. Remove the upper and lower mounting screws from the module or open the DIN latches using a flat-blade or Phillips screwdriver.

3. Move the bus lever to the right to disconnect or unlock the bus.

4. On the right-side adjacent module, move its bus lever to the right (unlock) to disconnect it from the module to be removed.

5. Gently slide the disconnected module forward.

If you feel excessive resistance, check that the module is disconnected from the bus and that both mounting screws are removed or DIN latches opened.

TIP

on page 3.

It may be necessary to rock the module slightly from front to back to remove it, or, in a panel-mounted system, to loosen the screws of adjacent modules.

6. Be sure that the bus lever on the module and on the right-side adjacent module are in the unlocked (fully right) position before installing the replacement module.

7. Slide the replacement module into the open slot.

8. Connect the modules by locking (fully left) the bus levers on the replacement module and the right-side adjacent module.

9. Replace the mounting screws or snap the module onto the DIN rail.

Mounting Expansion I/O

Compact High-density Analog Current Input Module 9

ATTENTION

During panel or DIN rail mounting of all devices, be sure that all debris, that is, metal chips or wire strands, is kept from falling into the module. Debris that falls into the module could cause damage when cycling power.

Minimum Spacing

Maintain spacing from enclosure walls, wireways, or adjacent equipment. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown.
