1. Safety Summary
Electrical Precautions
Take the following precautions to reduce the risk of electric shock, fire or explosion resulting in serious injury or death:
· Only use electrical protection equipment and tools suited for this installation. · Insulate the wired controller against moisture and temperature extremes. · Use specified cables between units and the controller. · If the power cord is damaged, it must be replaced by professionals from the service department or similar
departments of the manufacturer in order to avoid danger.
· Communication cabling must 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-Hitachi Air Conditioning 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 five 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. Verify with a meter and equipment.
· Use an exclusive power supply at the controller’s rated voltage. · Clamp electrical wires securely with a cord clamp after all wiring is connected to the terminal block.
In addition, run wires securely through the wiring access channel.
· When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular
intervals, but not too tightly.
· Make sure that the terminals do not come into contact with the surface of the electrical box.
If the terminals are too close to the surface, it may lead to failures at the terminal connection.
· Do not pour water on the controller as it could cause electric shock and/or damage the unit.
Do not use strong detergent such as a solvent. Clean with a soft cloth.

Use AWG 18 (0.82mm ) cable, (18-Gauge, 2-Conductor, Stranded Copper).

A. Communication cabling must be a minimum of 18-Gauge, 2-Conductor, Stranded Copper. Shielded cable must be considered for applications and routing in areas of high electronic interference (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-Hitachi Air Conditioning guidelines. Plenum and riser ratings for communication cables must be considered per application and local code requirements. The use of any other grade of cable other than that specified above can result in damage from EMI.
B. Maintain a distance more than 11-13/16 inches (30cm) between the communication cables (controller cable and communication cables) and power source of the indoor units. If this is not done, the unit can malfunction due to EMI generated by incoming power cables from the power source.
C. In systems where multiple indoor units are in synchronized control under a single controller, assign the refrigerant cycle numbers and address for indoor units without duplication.
D. Refer to the “Unit No. Setting” of each Installation and Maintenance manual provided with indoor unit when performing electrical wiring work between the controller and indoor units for setting the refrigerant cycle number and the indoor unit address.
E. No gap should exist between the controller cable and the cable access inlet of the controller box casing. If there is a gap, cover and seal the gap with vinyl tape. Failure to insulate against the penetration of moisture and insects can result in degraded performance and damage to the unit.
F. If case of operating with two controllers (Primary and Secondary), set the primary and secondary controllers by selecting the appropriate function for those controllers.
