Powering the FP-3000
Caution Connect the FP-3000 to the terminal base before
applying power to the FP-3000 to avoid damaging the
FP-3000 or a terminal base.
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. 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.
The power connector is a 6-pin screw terminal connector whose
pinout is shown in Figure6.
Figure 6. FP-3000 Power Connector Pinout
Connect the primary power supply to the center V and C pair. You
can connect an optional backup power supply to the left V and
Cpair. The right V and C pair provides a convenient means of
connecting power to the V and C terminals of a terminal base.
Figure6 shows this optional connection.
