Wiring Diagram Notes
1. POWER WIRING
Consult local building codes and project specifications for wiring requirements.
CAUTION: Maintain power source polarity otherwise equipment may be
damaged.
WARNING: Switch or circuit breaker must be included in the installation and
located where it is easily reached and marked as a disconnecting device for the
equipment. Power source must be current limited to less than 8-amps.
2. COMMUNICATIONS WIRING
Cable Type; Use low-capacitance cable, Windy City Wire # 042002 or equivalent
for BACnet and AccuNet wiring.
Termination; Install 120-ohm resistors /- terminals on the first & last
device on network segment. Failure to do so will result in unreliable
communications.
Ground; the cable shield shall be grounded at one end of the network segment
only.
