Connect Power to the Series A L1 CompactLogix
5370 Controllers
This appendix explains how to connect power to the series A L1 CompactLogix™
5370 controllers.
CompactLogix 5370 L1,
Series A, Controller Power
Connection
The external power supply must be dedicated to the embedded supply of the
controller. The external power supply converts 115/230V AC power to 24V DC
or other application-required DC voltage that is within the operating range of
the controller.

IMPORTANT
This section describes how to power the controller via the VDC+ and VDC-
terminals.
Connections to the VDC+ and VDC- terminals
do not
provide power to input or
output devices that are connected to the embedded I/O modules of the
controller or local expansion modules. Power must be connected to the FP+
and FP- terminals to provide power to input or output devices that are
connected to the embedded I/O modules of the controller or local expansion
modules.
For more information on how to provide power to input or output devices that
are connected to the embedded I/O modules of the controller and local
expansion modules, see
WARNING:
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 100VA maximum or equivalent. The
controller power requirement is 50VA.
