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.

WT07935X04

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 touch panel, switches,

or buttons with a sharp object.

To avoid injury from broken glass, do not apply excessive force to the glass parts.

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.

WT07935X04

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.

WT07935X04

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.
