About the Power Supplies
ControlLogix power supplies are used with the 1756 chassis to provide 1.2V, 3.3V, 5V, and
24V DC power for all modules installed in the chassis. The non-redundant power supplies are
mounted on the left end of the chassis, where they are plugged directly into the backplane.

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://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.

Environment and Enclosure
Prevent 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), at altitudes
up to 2000 m (6562 ft) 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 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, for additional installation
requirements, Allen-Bradley publication 1770-4.1.
•NEMA Standards publication 250 and IEC publication 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 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.

Connect the Power
Use 2.5 mm2(14 AWG) 75 °C (167 °F) copper wire with 1.2 mm (3/64-in.) insulation to
connect power. Follow these steps for each wire (high side (L1), low side (L2/N), and
ground) to connect power.
1. Turn the screw counterclockwise to open the wiring terminal.
WARNING If you connect or disconnect wiring while the field-side 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.
IMPORTANT The third terminal from the top (between low side and ground) is not used on the 1756
power supplies.

Activate the Power Supply
Flip the power switch to the up position to turn the power supply on.
Determine the Input Power Requirements/Transformer Sizing
These graphs show the input power requirements for the power supplies, given the power
they are providing to the modules in the chassis.
The vertical axis of each graph shows the backplane power consumed by all of the modules in
the chassis; the horizontal axis shows input power requirements of the power supply.

Publication 1756-IN613A-EN-P - December 2008
To use the graphs, complete this procedure.
1. Add all of the backplane power, that is, Watts, for all of the modules in the chassis.
2. Find the number from step 1 on the vertical axis.
3. Follow that value to the right until it intersects the line on the graph.
4. Find the associated input-power rating consumed by the power supply on the
horizontal axis.
For example, if the power consumption of all of the modules in the chassis is 30 Watts, a
1756-PH75 series B power supply consumes approximately 42 Watts of Real Power.

Status Indicators
ControlLogix power supplies have a green status indicator that remains ON during normal
operation.
If the indicator turns OFF during operation, follow these steps.
1. Verify that the line voltage is within the specified range.
2. If the indicator remains OFF, cycle line power OFF.
3. Loosen the screws holding the power supply to the chassis.
See page 7 for the location of the screws on the power supply.
4. Slide the power supply out so that the rear connector is disconnected.
5. Reapply input power.
6. If the indicator:
•turns ON:
a. Verify that the module loads in the system are within the output rating of the
power supply.
b. Power down the power supply.
c. Reinstall the power supply in the chassis.
•turns OFF, return the power supply to your local Rockwell Automation
distributor.
