CompactLogix 5380 Controllers
Install the Controller onto the DIN Rail
1. Confirm that the DIN rail latches are closed.
2. If the DIN rail latches are open, gently push the rear latch back
until the front latch pops up and clicks.
3. Position the controller so that the back of it faces the DIN rail.
4. Press the controller against the DIN rail until you hear a click.
5. Confirm that the controller is latched securely.
Connect External Power Supplies to the Controller
Before you connect MOD power or SA power to the RTBs on the
CompactLogix 5380 controller, complete the following tasks:
• Read
System Power Considerations on page 7.
• Confirm that the external power supplies that supply MOD
power and SA power are adequately sized for your
CompactLogix 5380 system. For more information, see
page 7.
• Install the MOD power RTB and the SA power RTB, if used,
on the controller.
• Verify that the external power supplies that provide MOD
power and SA power are turned off.
Install the MOD Power RTB
1. Hook the bottom of the MOD power RTB on the controller.
2. Push the RTB against the controller until you hear a click.
.
3. Push the RTB handle against the RTB until you hear a click.
Connect MOD Power
Before you connect an external power source to the MOD power RTB,
make sure that the MOD power source is properly sized.
1. Verify that the external power supply is not powered.
2. Strip insulation from the wires that you connect to the RTB.
WARNING: If you insert or remove the controller while power is
on, an electrical arc can occur. This could cause an explosion in
hazardous location installations. The controller does not support
"Removal and Insertion Under Power" (RIUP) capability. Do not
connect or disconnect the controller while power is applied. Be
sure that power is removed before proceeding.
ATTENTION: Do not remove or replace the controller while power
is applied. Interruption of the backplane can result in
unintentional operation or machine motion.

WARNING: If you connect or disconnect the Removable Terminal
Block (RTB) with power applied, an electrical arc can occur. This
could cause an explosion in hazardous location installations.
The Removable Terminal Block (RTB) does not support "Removal
and Insertion Under Power" (RIUP) capability. Do not connect or
disconnect the Removable Terminal Block (RTB) while power is
applied. Be sure that power is removed before proceeding.
IMPORTANT Your application can require a power control device, for example,
a switch, between the external 24V DC power source and the
controller to control when the controller is powered. If so, you
must install the power control device at the VDC+ terminal on
the RTB.
If you install the power control device at the VDC- terminal, the
controller can fail to power up or power down properly.
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.
