(Electric shock hazards)
Do not install the controller where there is a risk of leaking flammable gas.
If flammable gas accumulates around the controller, it may ignite and cause a
fire or explosion.
To reduce the risk of shorting, current leakage, electric shock, malfunctions,
smoke, or fire, do not install the controller in a place exposed to water or in a
condensing environment.
Controller must be installed by qualified personnel according to the
instructions detailed in the Installation Manual.
Improper installation may result in electric shock or fire.
Properly dispose of the packing materials. Plastic bags pose 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 fire or explosion, do not place flammable materials or
use flammable sprays around the controller.
To reduce the risk of damage to the controller, do not directly spray insecticide
or other flammable sprays on the controller.
To reduce the risk of injury, wear protective gear when working on the
