Install the CompactLogix 5370 L1 Controller Chapter 2
3. If an I/O module is installed, snap the RTB handle into place on the
module.
Connect Power to the Controller (Series B)
For information to connect power to a series A L1 controller, see Appendix C.
WARNING: When you connect or disconnect the RTB with field-side
power applied, an electrical arc can occur. This can cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
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.
The external power supply can be used to power both the VDC+/- and
FP+/- terminals on the series B L1 controller, see page 144
.
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 page 144
.
