York WIRED CONTROLLER CIW01

- Communication cabling shall be a minimum of 18-Gauge, 2-Conductor, Stranded Copper.

Shielded cable must be considered for applications and routing in areas of high EMI and other sources of potentially excessive electrical noise to reduce the potential for communication errors. When shielded cabling is applied, proper bonding and termination of the cable shield is required as per Johnson Controls guidelines.

Plenum and riser ratings for communication cables must be considered per application and local code requirements.

● The polarity of the input terminals is important, so be sure to match the polarity when using contacts that have polarity.

● Highly dangerous electrical voltages may be used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death.

● Before installing the controller or remote devices, ensure that the indoor and outdoor unit operation has been stopped. Further, be sure to wait at least fi ve minutes before turning off the main power switch to the indoor or outdoor units. Otherwise, water leakage or electrical breakdown may result.

● Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the main power supply.; Before connecting or servicing the controller or cables to indoor or outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected. Check with a meter and equipment.

● Use an exclusive power supply at the controller’s rated voltage.

● Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit breaker, and so forth) with the specified capacity. Ensure that the wiring terminals are tightened securely to recommended torque specifications.
