Connect Power to the Series A L1 CompactLogix 5370 Controllers
Power is connected to the controller via a removable connector that is connected
to the front of the controller. The following graphic shows the connector.
Consider these points before completing the steps in this section:
•
This section describes how to connect an external 24V DC power source
to the CompactLogix 5370 L1 controller.
For information on how to provide field power to input and output
devices that are connected to the embedded I/O modules of the controller
and local expansion modules via the removable connector, see
.
•
The external power supply that provides power to the
CompactLogix 5370 L1 controller must be dedicated to power
the controller.
•
You must use a separate, dedicated external 24V DC power source to
connect power to other terminals on the removable connector and devices
in the system, for example, the FP+ terminal or a barcode scanner,
respectively.
•
The external 24V DC power source that is connected to the VDC+ and
VDC- terminals on the removable connector must reside in the same
enclosure as the CompactLogix 5370 L1 controller.
IMPORTANT
The controller is grounded once it is installed on a DIN rail as described in
.
ATTENTION:
You must use an external power supply that is Class 2 or
SELV-listed.
