YCCS System Manager and Zone Coordinator Installation Instructions 

3

428546-YIM-C-1110

For applications where the supervisory controller is 
mounted inside a panel or enclosure, follow these 
additional guidelines:

Follow the manufacturer’s instructions when 

mounting the enclosure.

Do not install the supervisory controller in airtight 

enclosures.

Do not install heat-generating devices in the 

enclosure with the supervisory controller or near 
the enclosure that may cause the ambient 
temperature to exceed 50°C (122°F).

Mounting the Controller

To mount the controller on a vertical surface:

1. Hold the controller mounting base up to the wall 

and mark the location of the wall mount holes 
(Figure 2).  

2. Drill holes in the wall at the locations marked.

3. Position the mounting base, insert the screws 

through the holes in the base, and carefully tighten 
the screws. 

4. Line up the side tabs on the face of the controller 

with the tabs on the mounting base and carefully 
snap the face of the controller in place. 

Wiring 

Power Supply, Network, and Communication 
Bus Connections  

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.

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).

IMPORTANT:

Do not overtighten the mounting 

screws. Overtightening the screws may damage the 
controller housing.

IMPORTANT:

Ensure the BAS network wiring 

meets the specifications in this section.

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 
damage the controller by sharing power with other 
devices.
