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.
EXPLOSION HAZARD

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.
• If you insert or remove the module while backplane power is on, an
electric 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.
• The module does not support “Removal and Insertion Under Power”
(RIUP) capability. Do not connect or disconnect the module while power
is applied. Be sure power is removed before proceeding.

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.).

5. Repeat steps 3 and 4 using terminals I and J for the second adapter.
6. Connections D, E and F are used to pass 120/230V AC power to adjacent 1794
power supplies, or to power any corresponding120/230V AC modules in your
FLEX I/O system.
Example of Using a 1794-PS13 Power Supply to Power 4 Adapter Modules
ATTENTION: The total length of wire for terminals H, I, J and G must not
exceed 3m (9.8ft). Exceeding the 3m (9.8ft) length can reduce noise immunity.
ATTENTION: Input and output wiring must be in accordance with Class I,
Division 2 wiring methods and in accordance with the authority having
jurisdiction.
