Wiring
Power Supply, Network, and Communication
Bus Connections
IMPORTANT: Ensure the BAS network wiring
meets the specifications in this section.
See Figure 1 and Figure 3 for the location of System
Manager or Zone Coordinator ports, modular jacks,
and terminal blocks.
Power Supply
The Zone Coordinator and System Manager requires a
dedicated Class 2, 24 VAC, 10 VA minimum power
supply.
IMPORTANT: The 24 VAC power should not be
shared with other network devices. Sharing power
with other network devices may cause noise,
interference, and ground loop problems. You may
4
damage the controller by sharing power with other
devices.
System Communication/Zone Communication Bus
Port
The YK-SMU2x-0 models support the System Bus. The
YK-ZCUxx0-0 models are designed to support one
System Communication Bus and one Zone
Communication Bus.
Connect a System Communication Bus to the 3-wire
terminal block plug labeled System Bus on the System
Manager (Figure 3).
