CAUTION
WARNING
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.
Properly dispose of the packing materials. Plastic bags
pose suffocation hazard to children.
Do not install the unit in a place where large amounts
of oil, steam, organic solvents, or corrosive gases,
such as sulfuric gas, are present or where
acidic/alkaline solutions or sprays are used frequently.
These substances can compromise the performance
of the unit or cause certain components of the unit to
corrode, which can result in electric shock, malfunc-
tions, smoke, or fire.
Precautions during installation
To reduce the risk of shorting, current leakage, electric
shock, malfunctions, smoke, or fire, do not wash the
controller with water or any other liquid.
Properly install all required covers to keep moisture
and dust out of the controller. Dust accumulation and
water can cause electric shock, smoke, or fire.
To reduce the risk of electric shock, malfunctions,
smoke or fire, do not operate the switches/buttons or
touch other electrical parts with wet hands.
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 or electric shock, stop the
operation and switch off the power supply before
cleaning, maintaining, or inspecting the controller.
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 controller.
To reduce the risk of electric shock or malfunctions, do
not touch the touch panel, switches, or buttons with a
pointy or sharp object.
To reduce the risk of injury and electric shock, avoid
contact with sharp edges of certain parts.
To avoid injury from broken glass, do not apply
excessive force on the glass parts.
