v
• Do not turn the main circuit power on or off in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink or braking resistor because they become very hot.
Doing so could cause burns.
• Setting the inverter to high speeds is easy. Check the specifications of the motor and
machinery before changing the setting.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.
Maintenance and inspection, and parts replacement
• Turn the power off and wait for at least five minutes before starting inspection. Further,
check that the LED monitor is unlit, and check the DC link circuit voltage across the P (+)
and N (-) terminals to be lower than 25 VDC.
Otherwise, electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified per-
sons.
• Take off the watch, rings and other metallic matter before starting work.
• Use insulated tools.
Otherwise, electric shock or injuries could occur.
Disposal
• Handle the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.
Others
• Never attempt to modify the inverter.
Doing so could cause electric shock or injuries.
GENERAL PRECAUTIONS
