YCCS System Manager and Zone Coordinator Installation Instructions
4
Connect a Zone Communication Bus to the 3-wire
terminal block plug labeled System Bus on the ZC
(Figure 4).
USB Port
The Universal Serial Bus (USB) port connects an
external memory storage device (USB memory stick,
Type U1 or U2) for backing up controller configuration
parameters or for performing upgrades.
Ethernet Port
The Ethernet connection (10 or 100 Mbps) is an 8-pin
RJ-45 network port (Figure 1). Use the Ethernet port to
connect to Internet Protocol (IP) networks for remote
user access.
Optional Internal Modem
Both the YK-SMU2-0 and the YK-ZCUx0-0 supervisory
controllers have an internal modem and a 6-pin RJ-11
modular jack. Insert a standard phone line plug to
connect the internal modem.
Wiring Guidelines
Follow these guidelines when wiring the System
Manager and Zone Coordinator controllers:
•
Securely mount the controller base before wiring.
See the
Mounting the Controller
section.
•
Route the supply power wires and communication
cables at least 50 mm (2 in.) away from the vent
slots on the sides of the controller housing.
•
Provide slack in the wires and cables. Keep cables
routed neatly around the controller to promote
good ventilation, Light-Emitting Diode (LED)
visibility, and ease-of-service.
Wiring the Controller
To wire the controller:
1. Connect the three System Communication Bus
wires to the 3-terminal block for the System
Manager and/or connect the three Zone
Communication Bus wires for the Zone
Coordinator (Figure 3 and Figure 4).
Note:
When the controllers are connected to the
System Communication Bus, you must set the
End-of-Line (EOL) switch to the ON position
(Figure 3 and Figure 4).
2. Connect the 24 VAC power supply wires from the
transformer to the terminal block (Figure 3 and
Figure 4).

CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
IMPORTANT:
Exceeding the controller electrical
ratings can result in permanent damage to the
controller and void any warranty.
IMPORTANT:
Use copper conductors only. Make
all wiring connections in accordance with local,
national, and regional regulations. Do not exceed
the System Manager or Zone Coordinator’s
electrical ratings.
IMPORTANT:
Prevent static electricity discharge to
the controllers. Static electric discharge may
damage the controller and void any warranties.
