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.

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.
