MOTOR SPECIFICATIONS
PRECAUTIONS ON USAGE
The following precautions should always be observed when using this machine. If
these, or the engine and electric motor specifications are disregarded, a serious
accident may occur.
• Installation of this machine must comply with laws and regulations of your country.
Contact us or our sales service agency if no laws and regulations are applied.
• Only personnel qualified according to laws and regulations of your country are
allowed to establish power connection between power supply equipment and this
machine.
Contact us or our sales service agency if no laws and regulations are applied.
• Operation and storage of this machine must satisfy the requirements listed below:
• Operating temperature: -10 to 40°C (no frost)
• Storage temperature: -20 to 60°C
• Operating humidity:
90%RH or less (no condensation)
• Atmosphere: Outdoor environment free from explosive, flammable, and
corrosive gases, moisture, and excessive dust particles
• Altitude: 1000m or less
• Vibration: 0.5G or less
• Turn “OFF” the power supply equipment breaker promptly in the event of anything
abnormal on the machine during operation. Fire or an electric shock may occur if
disregarded.
• Turn “OFF” the power supply equipment breaker promptly in the event of a power
failure during operation. Otherwise the machine may inadvertantly operate upon
energization.
• Always turn “OFF” the power supply equipment breaker before performing inspection
and maintenance of the electric system. An electric shock may occur during work if
disregarded.
In addition, notify all personnel at the workplace that inspection and maintenance are
being performed and attach a warning tag indicating “Operation Prohibited” to the
power supply equipment breaker so that other persons will not accidentally operate
the breaker.
• Always turn “OFF” the power supply equipment breaker and wait for 10 minutes or
longer before performing inspection and maintenance of the electric system.
Measure the voltage using a tester and ensure that no voltage is applied to the power
supply box.
• All the parts are at elevated temperatures immediately after machine operation.
Performing inspection and maintenance of the electric system under this condition
causes burns.
Wait until the temperature lowers, then execute the inspection/maintenance following
the procedure described in this manual.
• Do not spray water directly on the power supply box and inverter board.
Water entering the electrical system is dangerous and may cause faulty or improper
operations.
• Contact us or our sales service agency for repair of the inside of the inverter board.
