Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray,
removable, 3-terminal plug that fits into a board-mounted
jack on the top right of the controller.
Wire the 24 VAC supply power wires from the transformer
to the HOT and COM terminals on the terminal plug as
shown in
. The middle terminal on the supply
power terminal block is not used. See
for more
information about the Supply Terminal Block.
Figure 7: 24 VAC Supply Power Terminal Block Wiring
Note:
The supply power wire colors may be different on
transformers from other manufacturers. Refer to
the transformer manufacturer’s instructions and
the project installation drawings for wiring details.
Important:
Connect 24 VAC supply power to the
controller and all other network devices so
that transformer phasing is uniform across
the network devices. Powering network
devices with uniform 24 VAC supply power
phasing reduces noise, interference, and
ground loop problems. The controller does
not require an earth ground connection.
Wireless Network Applications
When configured for BACnet MS/TP communication, the
controller can also be installed in a wireless application
using an FX-ZFR1811 Series Wireless Field Bus Router.
To configure a controller for use with the FX-ZFR1811
Series Wireless Field Bus system:
1. Wire the input/output terminals and SA bus.
Note:
In wireless network applications, do not
connect any wires to the FC Bus terminal
block. (Connect the SA/FC terminal block on
an FX-PCX to an SA bus only.)
2. Connect the FX-ZFR1811 Wireless Field Bus Router
to the FC bus port (RJ-12 modular jack) on the front
of the controller.
3. Ensure that the controller's device address DIP
switches are set to the correct device address. See
4. Set DIP switch 128 to ON, which enables wireless
operation on the controller.
