v Trial Operation Maintenance and InspectionWARNING• Check to be sure that the front cover is attached before turning ON the power supply.An electric shock may occur.• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared,the machine may start moving suddenly.Also, design the machine so that human safety is ensured even when it is restarted.Injury may occur.• Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when itsfunction is set.Injury may occur.• Reset alarms only after confirming that the RUN signal is OFF.Injury may occur.CAUTION• Don't touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These canbecome very hot.Otherwise, a burn injury may occur.• Be sure that the motor and machine is within the applicable ranges before starting operation.Otherwise, an injury may occur.• Provide a separate holding brake if necessary.Always construct the external sequence to confirm that the holding brake is activated in the eventof an emergency, a power failure, or an abnormality in the Inverter.Failure to observe this caution can result in injury.• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevatorfrom dropping.Failure to observe this caution can result in injury.• Don't check signals while the Inverter is running.Otherwise, the equipment may be damaged.• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings.Otherwise, the equipment may be damaged.WARNING• Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremelydangerous.Doing so can result in electric shock.• Always have the protective cover in place when power is being supplied to the Inverter. Whenattaching the cover, always turn OFF power to the Inverter through the MCCB.Doing so can result in electric shock.• Turn OFF the main circuit power supply, wait for the time indicated on the front cover, and makesure the CHARGE indicator light has gone out, and then perform maintenance and inspection.The capacitor will remain charged and is dangerous.• Maintenance, inspection, and replacement of parts must be performed only by authorized person-nel.Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools.Failure to heed these warning can result in electric shock.
