Details of harm or damage
CAUTION Damage due to rough transportation.
CAUTION
Shortened lifetime of parts due to the use
in places where the product is exposed to
direct sunlight or the temperature is not
within the specified range.
CAUTION
Short-circuit failure due to the use in
places where the temperature is not
within the specified range or
condensation occurs.
DANGER
A cooling fan reaching a high temperature
exceeding 150 °C causes a fire on a
flammable wall.
CAUTION
Damage to parts due to entry of dust and
corrosive gases.
CAUTION
Shortened lifetime of parts due to
reduced cooling capability by placing the
product horizontally.
CAUTION
A cooling fan failed due to waterdrops
oil mist when the heat sink is positioned
outside.
DANGER
A fire is caused inside by an arc due to
screws loosened by vibrations.
