Make sure that dust and/or steam does not accumulate on the circuit board.
· When installing the unit in a hospital or other facility where
electromagnetic waves are generated from nearby
medical and/or electronic devices, be prepared for noise and Electromagnetic
Interference (EMI). Do not install where the waves can directly radiate into
the electrical box, controller cable, or controller. Inverters, appliances,
high-frequency medical equipment, and radio communications equipment. EMI may
cause the unit to malfunction. The operation of the unit may also adversely
affect these same devices. Install the unit at least 10 ft. (approximately 3m)
away from such devices.
· Locate the controller at a distance of at least 3 ft. (approximately 1m)
between the indoor unit and electric
lighting. Otherwise, the receiver part of the unit may have difficulty
receiving operation commands.
· If the wired controller is installed in a location where electromagnetic
energy is generated, make sure that the
wired controller is shielded and cables are sleeved inside conduit tubing.
· If there is a source of electrical interference near the power source,
install noise suppression equipment (filter). · During the test run, check the
unit’s operation temperature. If the unit is used in an environment where the
temperature exceeds the operation boundary, it may cause severe damage. Check
the operation temperature boundary in the manual. If there is no specified
temperature, use the unit within the operation temperature boundary of 32°F to
104°F (0°C to 40°C).
· Read this installation and maintenance manual for proper electrical wiring

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. Refer to Page 12 item F2 in chapter 6. Function Selection.
