FLEX I/O Power Supply Modules 3

Publication 1794-IN069E-EN-P - September 2018

Environment and Enclosure

Preventing Electrostatic Discharge

This equipment is intended for use in a Pollution Degree 2 industrial

environment, in overvoltage Category II applications (as defined in IEC 60664-1),

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

This equipment is not intended for use in residential environments and may not

provide adequate protection to radio communication services in such

environments.

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 or be approved for the application

if nonmetallic. 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 the following:

• Industrial Automation Wiring and Grounding Guidelines, 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 enclosures.

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.

Publication 1794-IN069E-EN-P - September 2018

Electrical Safety Consideration

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 or 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. Be sure to ground the DIN rail

properly. Refer to Industrial Automation Wiring and Grounding Guidelines,

Rockwell Automation publication 1770-4.1

, for more information.

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.

ATTENTION:

• If this equipment is used in a manner not specified by the manufacturer,

the protection provided by the equipment may be impaired.

• 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

in addition to requirements of all applicable codes, laws, and standards.

• Installation, adjustments, putting into service, use, assembly, disassembly,

and maintenance are required to be carried out by suitably trained

personnel in accordance with applicable code of practice.

• In case of malfunction or damage, no attempts at repair should be made.

The module should be returned to the manufacturer for repair. Do not

dismantle the module.

• This equipment is certified for use only within the surrounding air

temperature range of 0…55 °C (32…131 °F). The equipment must not be

used outside of this range.

• Use only a soft dry anti-static cloth to wipe down equipment. Do not use

any cleaning agents.

ATTENTION: All wiring must comply with applicable electrical installation

requirements (for example, N.E.C. article 501-4(b)).

North American Hazardous Location Approval

The following modules are North American Hazardous Location approved:

1794-PS13 and 1794-PS3.

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

equipment in your system are subject to investigation by the

local Authority Having Jurisdiction at the time of

installation.

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne

conviennent qu'à une utilisation en environnements de

Classe I Division 2 Groupes A, B, C, D dangereux et non

dangereux. Chaque produit est livré avec des marquages sur

sa plaque d'identification qui indiquent le code de

température pour les environnements dangereux. Lorsque

plusieurs produits sont combinés dans un système, le code

de température le plus défavorable (code de température le

plus faible) peut être utilisé pour déterminer le code de

température global du système. Les combinaisons

d'équipements dans le système sont sujettes à inspection par

les autorités locales qualifiées au moment de l'installation.

Install Your Power Supply Module

1. Hook the lip on the rear of the power supply module onto the top of the DIN

rail, and rotate the power supply module onto the rail.

2. Press the power supply module down onto the DIN rail until flush. Locking

tab C will snap into position and lock the power supply module to the DIN rail.

3. If the power supply module does not lock in place, use a screwdriver or similar

device to move the locking tab down while pressing the power supply module

flush onto the DIN rail, and release the locking tab to lock the power supply

module in place. If necessary, push up on the locking tab to lock.

4. Connect the power supply wiring as shown in Connect

Wiring for your Power

Supply Module below.

Note: For panel/Wall mounting, refer to publication 1794-TD013

, Panel Mounting Kit,

catalog number 1794-NM1.

ATTENTION: During mounting of all devices, be sure that all debris (metal

chips, wire strands, etc.) is kept from falling into the module. Debris that falls

into the module could cause damage on power up.

Connect Wiring for your Power Supply Module

Terminals A, B and C are 120/230V AC supply terminals. Terminals D, E and F are available

to daisychain this 120/230V AC power to other 1794-PS power supply modules. If applying

120/230V AC power to the power supply, you can also power the corresponding 120/230V

AC modules in your FLEX I/O system.

1. Connect the 120/230V AC power to the left side terminals on the connectors on

the left side of the power supply module as follows:

2. Connect terminal G (+24V DC) to the +24V DC terminal on the first adapter.

3. Connect terminal H (+24V DC common) to the +24V DC common terminal

on the first adapter.

4. Connections I and J are used to pass +24V DC power (G) and –24V common

(H) to the next adapter in the series (if required).

IMPORTANT

When wiring this power supply, torque terminal screws to 0.8 Nm

(7 lbs-in.).
