1. Safety precautions

►Thoroughly read the following safety precautions prior to installation.
►Observe these precautions carefully to ensure safety.
►After reading this manual, pass the manual on to the end user to retain for future

reference.

►The user should keep this manual for future reference and refer to it as necessary. This

manual should be made available to those who repair or relocate the units. Make sure
that the manual is passed on to any future air conditioning system user.

►All electrical work must be performed by qualified personnel.

: indicates a hazardous situation which, if not avoided, could result in

death or serious injury.

: indicates a hazardous situation which, if not avoided, could result in

minor or moderate injury.

: addresses practices not related to personal injury, such as product

and/or property damage.

1-1. General precautions

Do not install the controller in areas where large amounts of oil, steam, organic solvents,
or corrosive gases (such as ammonia, sulfuric compounds, or acids), or areas where
acidic/alkaline solutions or special chemical sprays are used frequently. These substances
may significantly reduce the performance and corrode the internal parts, resulting in
electric shock, malfunction, smoke, or fire.

To reduce the risk of injury, electric shock, or fire, do not alter or modify the controller.

To reduce the risk of electric shock, malfunction, smoke, or fire, do not touch the electrical
parts or USB memory with wet fingers.

To reduce the risk of injury or electric shock, before spraying a chemical around the
controller, stop the operation and cover the controller.

To reduce the risk of burns, do not touch the electrical parts with bare hands during and
immediately after operation.

To reduce the risk of injury, keep children away while installing, inspecting, or repairing the
controller.

Test runs, inspection, and service must be performed by qualified personnel in accordance
with this manual. Incorrect use may result in injury, electric shock, malfunction, or fire.

If you notice any abnormality, stop the operation and turn off the controller. Continuing the
operation may result in electric shock, malfunction, or fire.

Properly install all required covers to keep moisture and dust out of the controller. Dust
accumulation and the presence of water may result in electric shock, smoke, or fire.

To reduce the risk of frostbite, burns, injury, or electric shock, keep the equipment out of
the reach of children.

3

WT07417X01

To reduce the risk of fire or explosion, do not place flammable materials or use flammable
sprays around the controller.

To reduce the risk of electric shock or malfunction, do not touch the switches or buttons
with a sharp object.

To reduce the risk of injury, electric shock, or malfunction, avoid contact with the sharp
edges of certain parts.

To reduce the risk of injury, wear protective gear when working on the controller.

Wear protective gear when working on the controller. High-voltage parts pose a risk of
electric shock, and high-temperature parts pose a risk of burns.

1-2. Precautions for unit installation

Do not install the controller where there is a risk of flammable gas leaks. If flammable gas
accumulates around the controller, it may ignite and cause a fire or explosion.

Properly dispose of the packing materials. Plastic bags pose a suffocation hazard to
children.

Take appropriate safety measures against earthquakes to prevent the controller from
causing injury.

To prevent injury, install the controller on a flat surface strong enough to support its
weight.

To reduce the risk of short circuits, current leakage, electric shock, malfunction, smoke, or
fire, do not install the controller in a place exposed to water or in a condensing
environment.

The controller must be installed by qualified personnel according to the instructions
detailed in this manual. Improper installation may result in electric shock or fire.

1-3. Precautions for electrical wiring

To reduce the risk of malfunction, smoke, fire, or damage to the controller, do not connect
the power cable to the signal terminal block.

To reduce the risk of malfunction, smoke, fire, or damage to the controller, do not apply a
power supply voltage in excess of that specified.

Properly secure the cables in place and provide adequate slack in the cables so as not to
stress the terminals. Improperly connected cables may break, overheat, and cause smoke
or fire.

To reduce the risk of injury or electric shock, switch off the main power before performing
electrical work.

4

WT07417X01

Electrical work must be performed by qualified personnel in accordance with local
regulations and the instructions provided in this manual. Only use specified cables and
dedicated circuits. Inadequate power source capacity or improper electrical work will
result in electric shock, malfunction, or fire.

To reduce the risk of electric shock, install an overcurrent breaker and an earth leakage
breaker on the power supply. To reduce the risk of electric shock, smoke, or fire, install an
overcurrent breaker for each controller.

Only use properly rated breakers (earth leakage breaker, local switch <switch + fuse that
meets local electrical codes>, moulded case circuit breaker, or overcurrent breaker). The
use of improperly rated breakers or the substitution of fuses with steel or copper wire may
result in electric shock, malfunction, smoke, or fire.

To reduce the risk of current leakage, overheating, smoke, or fire, use properly rated
cables with adequate current carrying capacity.

Proper grounding must be provided by qualified personnel. Do not connect the protective
ground wire to a gas pipe, water pipe, lightning rod, or telephone wire. Improper grounding
may result in electric shock, smoke, fire, or malfunction due to electrical noise
interference.

To reduce the risk of short circuits, electric shock, or malfunction, keep wire pieces and
sheath shavings out of the terminal block.

To reduce the risk of short circuits, current leakage, electric shock, or malfunction, keep
the cables out of contact with controller edges.

To reduce the risk of electric shock, malfunction, or fire, seal the gap between the cable
and the end of the conduit tube with putty.

To reduce the risk of injury, do not touch the burrs of the knockout holes.

1-4. Precautions for relocating or repairing the unit

The controller must be repaired or moved only by qualified personnel. Do not disassemble
or modify the controller. Improper installation or repair may result in injury, electric shock,
or fire.

To reduce the risk of short circuits, electric shock, malfunction, or fire, do not touch the
circuit board with tools or with your hands, and do not allow dust to accumulate on the
circuit board.

1-5. Additional precautions

To avoid damage to the controller, use appropriate tools to install, inspect, or repair the
controller.

To prevent unauthorized access, always use a security device such as a VPN router when
connecting to the Internet.

5

WT07417X01

Take appropriate measures against electrical noise interference when installing the
controller in hospitals or radio communication facilities. Inverter, high-frequency medical,
or wireless communication equipment as well as power generators may cause the air
conditioning system to malfunction. The air conditioning system may also adversely affect
the operation of these types of equipment by creating electrical noise.

To avoid malfunction, do not bundle power cables and signal cables together or place
them in the same metallic conduit.

To avoid damage to the controller, do not overtighten the screws.

To avoid deformation and malfunction, do not install the controller in direct sunlight or
where the ambient temperature may exceed 55°C (131°F) or drop below -10°C (14°F).

This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play
with the appliance.
