Figure 5: SA Bus Terminal Block Wiring

Note:

The SA PWR/SHLD terminal does not supply 15
VDC. The SA PWR/SHLD terminal is isolated and
can be used to connect (daisy chain) the 15 VDC
power leads on the SA bus (

Figure 5

) or the cable

shields on the FC bus (

Figure 4

). The SA bus

supervisor supplies 15 VDC to devices on the SA
bus requiring power.

SA/FC Bus Port

The SA/FC bus port on the front of the controller is an
RJ-12, 6-position modular jack that provides a connection
for devices on the SA bus, a Bluetooth

®

Commissioning

Converter, ZigBee

wireless dongle, or an FX-ZFR1811

Wireless Router (depending on which bus the controller
is operating on).

The SA/FC bus port is connected internally to the SA/FC
bus terminal block. See

Table 5

for more information.

The SA/FC bus port pin assignment is shown in

Bus and FC Bus Ports on Controllers

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

Figure 7

. The middle terminal on the supply

power terminal block is not used. See

Table 5

for more

information about the supply terminal block.

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.
