Prevent Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which ca n 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.
Before You Begin
Consider the following before installing a CompactLogix 5370 L2 controller:
• The control system includes a controller, an embedded power supply,
and embedded I/O points.
• The embedded power supply is a 24V DC input, isolated power supply.
• You must connect an external Class 2 or SELV-approved power supply
to provide 24V DC power to the system.
• The controllers have embedded I/O points. You wire the input and
output points via a removable connector.
• The controller supports the use of Compact I/O
1769 CompactBus backplane as local expansion modules.
• You must terminate the end of the CompactBus via a 1769-ECR right
end cap.

• You cannot remove nor install Compact I/O modules while the
controller is powered.
ATTENTION: CompactLogix 5370 L2 control systems do not support removal and
insertion under power (RIUP). Removing a 1769 Compact I/O module or end cap will
generate a controller fa ult and may also result in damage to system components.
Install the Secure Digital Card
The CompactLogix 5370 L2 controller is shipped from the factory with the
1784-SD1 SD card installed.
Complete these steps to re-install an SD card that has been removed from the
controller back into the controller or if installing a new SD card into the
controller.
WARNIN G: When you insert or remove the SD card while 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.
1. Verify that the SD card is locked or unlocked according to your
preference before installation. Consider the following points:
– If the card is unlocked, the controller can write data to it or read data
from it.
– If the card is locked, the controller can only read data from it.

IMPORTANT
TIP
TIP
Mount the Controller on a Panel
Use two M4 or #8 panhead screws to mount the controller. Mounting screws are
required on every module. Use this procedure to use the assembled modules as a
template for drilling holes in the panel.
Due to module mounting hole tolerance, it is important to follow these procedures.
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of
all module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any
previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel and check for proper hole
alignment.
The grounding plate, that is, where you install the mounting screws, grounds
the module when it is panel-mounted.
6. Use the mounting screws to attach the modules to the panel.
If you are mounting more modules, mount only the last one of this group and
put the others aside. This reduces remounting time when you are drilling and
tapping the next group of modules.
7. Repeat steps 1…6 for any remaining modules.

Mount the Controller on the DIN Rail
You can mount the controller on the following DIN rails:
• EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
• EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
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.
1. Hook the DIN rail latch at the top of the back of the controller on the
DIN rail.
2. Swing the controller downward until it touches the DIN rail and press
the controller against the DIN rail until it clicks in place.
The click verifies that controller is locked on the DIN rail.
Ground the System
ATT EN TI ON : 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.
Refer to Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation
publication 1770-4.1
, for additional information.

Connect Power to the Controller
You must connect an external Class 2 or SELV-listed power supply to the
controller’s embedded power supply. The external power supply converts
115/230V AC power to 24V DC.
WARNIN G: Do not connect directly to line voltage. Line voltage must be
supplied by a suitable, approved isolating transformer or power supply having
short circuit capacity not exceeding 100 VA maximum or equivalent.
Rockwell Automation Publication 1769-IN090A-EN-P - April 2012
CompactLogix 5370 L2 Controllers 11
Consider these points before completing the steps in this section:
• An external power supply must reside in the same enclosure as the
CompactLogix 5370 L2 controller.
If the external power supply and controller are located in separate
enclosures, an electrical arc can occur when power is applied.
• Not all Class 2 or SELV-listed power supplies are certified for use in all
applications, for example, use in both nonhazardous and hazardous
environments.
Before installing an external power supply, consult all specification and
certification information to verify that you are using an acceptable
external power supply.
• Yo u must wire power according to the wiring specifications, for example,
the maximum screw torque on a power supply terminal, listed in the
CompactLogix 5370 L2 Controllers Product Information Sheet,
publication 1769-PC010
.
Complete these steps to connect power to the CompactLogix 5370 L2
control system.
1. Verify that the external power supply is installed properly.
2. If appropriate, verify that the power setting on the supply is configured
to match the voltage source and that the supply is not powered.
3. Connect a wire to a +24V DC terminal on the external power supply.
WARNI NG: 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.
4. Strip 8 mm (0.31 in.) insulation from the end of the wire that you will
connect to the +24VDC terminal on the controller.

5. Connect the wire to the +24VDC terminal on the controller.
6. Connect a wire to a -24V DC terminal on the external power supply.
7. Strip 8 mm (0.31 in.) insulation from the end of the wire that you will
connect to the COM terminal on the controller.
8. Connect the wire to the COM terminal on the controller.
If your application requires a power control device, for example, a switch or relay,
between the external power supply and the CompactLogix 5370 L2 controller’s
embedded power supply to control when the controller is powered, you must install
the power control device at the +24VDC terminal on the controller.
If you install the power control device at the COM terminal, the CompactLogix 5370
L2 controller may not power up or power down properly.
Rockwell Automation Publication 1769-IN090A-EN-P - April 2012
The previous section describes how to wire terminals +24VDC and COM on the
CompactLogix 5370 L2 controller. They are the only terminals you wire to power the
CompactLogix 5370 L2 control system.
You should only use the FG terminal as appropriate when connecting a field device to
the controller.

Wiring the Embedded I/O Modules
Complete these steps to wire the input and output points on the
CompactLogix 5370 L2 controller.
1. Verify that the control system is not powered.
2. Strip 10 mm (0.39 in.) insulation from the end of the wire.
3. Push the wire into the connector hole until it is securely in place.
If your wire is too thin to push into the connector hole for secure
placement, we recommend that you connect the wire to a ferrule and
then insert it into the connector hole.
4. Repeat step 2
for all embedded I/O wires needed in your application.
To remove a wire from the removable connector, complete these steps.
1. Verify that the control system is not powered.
2. Use a small screwdriver to push on the spring release clip and pull the
wire out.
