Connect Power to the FP-3000
An 11–30 VDC power supply is required by each FP-3000 on your
network. The FP-3000 filters and regulates this supplied power and
provides power for all the I/O modules in the bank. Therefore, you do not
need to provide power separately to each FieldPoint I/O module in
the bank.
The power connector is a 6-pin screw terminal power connector whose
pinout is shown in Figure2-10. See Figure 2-11 for the location of the
power connector.
Figure 2-10. FP-3000 Power Connector Pinout
Connect the primary power supply to the center V and C pair with the
positive and negative wires on your power cable in the V and C terminals,
respectively. You can connect an optional backup power supply to the left
V and C pair. The right V and C pair provides a convenient means of
connecting power to the V and C terminals of a terminal base. Figure 2-10
shows this optional connection.
If your field I/O devices need to be powered separately, you can use the
terminals provided on each terminal base for such power supply
connections. Refer to the documentation that came with your terminal base
and I/O module for more information on powering your field I/O devices.

Calculating Power for a FieldPoint Bank

The power requirements for a FieldPoint bank that uses an FP-3000
network module are calculated as follows:
Power = 6 watts + 1.15 * (I/O Module Consumption)
