• Earthing is accomplished through mounting of modules on rail.
• Devices shall be used in an environment of not more than Pollution Degree 2.
• This equipment is not resistant to sunlight or other sources of UV radiation.
Energy Storage Considerations
WARNING: This product contains stored energy. If your application requires the controller to deplete its residual stored energy to 40 μJ or less before you
transport it into or out of the application, use only the 1769-L30ER-NSE controller. Complete these steps before you remove the controller.
1. Turn off power to the chassis.
2. After you turn off power, the controller’s OK status indicator transitions from green to steady red to OFF.
3. Wait at least 15 minutes for the residual stored energy to decrease to 40 μJ or less before you remove the controller.
4. There is no visual indication of when the 15 minutes has expired. You must track that time period.
Prevent Electrostatic Discharge
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.
Removal and Insertion Under Power
ATTENTION: The CompactLogix 5370 L3 control systems do not support removal and insertion under power (RIUP). These events occur while the
CompactLogix system is under power:
• Any break in the connection between the power supply and the controller, for example, removing the power supply, controller, or an I/O controller, can
subject the logic circuitry to transient conditions above the normal design thresholds and can result in damage to system components or unexpected
behavior.
• Removing an end cap or an I/O controller faults the controller and can also result in damage to system components.

Install the Secure Digital Card
The controller ships from the factory with the 1784-SD1 Secure Digital (SD) card installed.
1. Verify that the SD card is locked or unlocked according to your preference. Consider the following when deciding to lock the card before installation:
If the card is unlocked, the controller can write data to it or read data from it.
2. Open the door for the SD card.
3. Insert the SD card into the SD card slot, following the orientation logo that is printed on the card.
4. Gently press the card until it clicks into place.
5. Close the SD card door.
Assemble the System
1. Verify that line power is disconnected.
2. Make sure that the bus lever of the 1769 Compact I/O™ power supply is in the unlocked position, that is, leaning to the right.
3. Use the upper and lower tongue-and-groove slots to secure the controller and power supply together.
4. Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other.
5. Use your fingers or a small screwdriver to push the bus lever on the power supply back slightly to clear the positioning tab.
6. Move the bus lever of the power supply fully to the left until it clicks; make sure that it locks.
7. If your system does not use any local expansion modules, use the tongue-and-groove slots described earlier to attach a 1769-ECR or 1769-ECRK Compact I/O end
cap terminator to the last module in the system.
8. Wire the 1769 Compact I/O power supply according to the directions in the Compact I/O Expansion Power Supplies Installation Instructions, publication 1769-IN028.

Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION: Do not remove or replace this module while power is applied. Interruption of the backplane can result in unintentional operation or
machine motion.
WARNING: Remove power before removing or inserting this module. 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.
IMPORTANT You must install an end cap onto the right side of the CompactLogix 5370 L3 controller system either at the end of the controller or at the
end of any local expansion modules that can be installed onto the controller.
The covering covers the exposed interconnections on the right side of the controller. Failure to use a protective covering could result in
equipment damage or injury from electric shock.

CompactLogix 5370 L3 Controller Installation Instructions
Mount the System
You can mount a CompactLogix 5370 L3 control system on a DIN rail or on a panel.
• Mount the system so that the modules are horizontal to each other. If you separate modules into multiple banks, the banks can be vertical or horizontal to
each other.
• Allow 50 mm (2 in.) of space on all sides.
• Use two M4 or #8 pan head screws for panel mounting.
• Use EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.) or EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.) DIN rails.
Ground the System
Network Connectors and Cable
This product has a USB port.
This product has two Ethernet ports.
ATTENTION: During panel or DIN rail mounting of all devices, be sure that all debris (such as metal chips or wire strands) is kept from falling into the
controller. Debris that falls into the controller could cause damage while the controller is energized.
ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated 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. See Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation
publication 1770-4.1, for more information.
ATTENTION: This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. Additional grounding connections
from the power supply's mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded.
See Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information.
WARNING: Do not use the USB port in hazardous locations.
ATTENTION: The USB port is intended only for temporary local programming purposes and is not intended for permanent connection.
The USB cable is not to exceed 3.0 m (9.84 ft) and must not contain hubs
