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.rockwellautomation.com/literature/) 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,

Environment and Enclosure

Preventing Electrostatic Discharge

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), and at altitudes of up to 2000 m (6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment according

to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with

electromagnetic compatibility in residential and other environments due to

conducted and radiated disturbances.

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, Rockwell

Automation publication 1770-4.1, for additional installation requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the

degrees of protection provided by different types of enclosure.

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 wrist strap.

• 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.

ATTENTION: This product is grounded through the DIN rail to chassis ground.

Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The

use of other DIN rail materials (for example, aluminum, 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 (7.8 in.) and

use end-anchors appropriately.

ATTENTION: To comply with the CE Low Voltage Directive (LVD), this

equipment must be powered from a source compliant with the Safety Extra Low

Voltage (SELV) or Protected Extra Low Voltage (PELV).

The following information applies when

operating this equipment in hazardous

locations:

Informations sur l’utilisation de cet

équipement en environnements dangereux:

Products marked "CL I, DIV 2, GP A, B, C, D" are suitable for

use in Class I Division 2 Groups A, B, C, D, Hazardous

Locations and nonhazardous locations only. Each product is

supplied with markings on the rating nameplate indicating

the hazardous location temperature code. When combining

products within a system, the most adverse temperature code

(lowest "T" number) may be used to help determine the

overall temperature code of the system. Combinations of

Install the Mounting Base

To install the mounting base on the DIN rail, proceed as follows:

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 the DIN rail. The mounting base snaps

into place. Be sure that the orange DIN rail locking screw is in the horizontal

position and that it has engaged the DIN rail.

ATTENTION: Do not discard the end cap. Use this end cap to cover the exposed

interconnections on the last mounting base on the DIN rail. Failure to do so

could result in equipment damage or injury from electric shock.

Slide the mounting base until the

interlocking side pieces engage the

adjacent module or adapter.

POINT I/O RTD and Isolated Thermocouple Input Modules 9

Publication 1734-IN011I-EN-E - June 2015

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.

ATTENTION: When you insert or remove the module 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

module and its mating connector. Worn contacts may create electrical

resistance that can affect module operation.

1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise

until the number required for the type of module being installed 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 into the mounting base.

4. 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 of the wirings. 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.
