Figure 2-15 shows the 6-pin screw-terminal power connector on the
cFP-20xx.

1. Connect the positive lead of the primary power supply to one of the
V1 terminals and the negative lead to one of the C terminals.
2. If you are using a backup power supply, connect the positive lead to V2
and the negative lead to one of the C terminals. The cFP-20xx generally
uses the power supply with the higher voltage level. V2 is isolated from
the other V terminals.
3. If module-to-module isolation is important in your application, use a
separate power supply for each module that needs external power. If
your application does not require module-to-module isolation, you can
cascade power, using the same power supply for all modules that
require external power.
Caution Cascading power defeats isolation between the cascaded modules.
4. Refer to the operating instructions for the power requirements of each
I/O module. If a module requires external power, connect a power
supply to the appropriate input terminals on the connector block. If you
want to power field I/O devices from a connector block, supply power
to the connector block, and then connect the connector block output
terminals to the field device.
Powering Up the cFP-20xx
Check the DIP switches on the controller, making sure that the RESET IP
switch is not enabled. Refer to Chapter 3, Feature Descriptions, for a
description of the DIP switches. Plug in each power supply to the Compact
FieldPoint system. The cFP-20xx runs a power-on self test (POST) that
takes several seconds. You should see the POWER and STATUS LEDs
