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.
