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 short circuits, current leakage, electric shock, malfunction, smoke, or
fire, do not wash the controller with water or any other liquid.
To reduce the risk of electric shock, malfunction, smoke, or fire, do not touch the electrical
parts, USB memory, or touch panel 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 injury, keep children away while installing, inspecting, or repairing the
controller.
If you notice any abnormality (e.g., burning smell), stop the operation, turn off the
controller, and consult your dealer. 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 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.
