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.
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.
The power requirements for a FieldPoint bank that uses an FP-1600
network module are calculated as follows:
Power = 7 Watts + 1.15 * ∑(I/O Module Consumption)
This is the amount of power the FP-1600 network module consumes from
the power supply to power itself and the I/O modules. It does not include
any power consumed by devices that you wire to the terminal bases.
The operating instructions for each FieldPoint I/O module contain power
consumption information.
