Mitsumi electronic FR-F520-0.75K, 55K instruction manual Emergency stop, Treat as industrial waste

CAUTION

!The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the equipment.

!Do not modify the equipment.

!The electronic overcurrent protection does not guarantee protection of the motor from overheating.

!Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

!Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.

!Take measures to suppress harmonics. Otherwise power harmonics from the inverter may heat/damage the power capacitor and generator.

!When a 400V class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

!When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set the required parameters before starting operation.

!The inverter can be easily set for high-speed operation. Before changing its setting, examine the performance of the motor and machine.

!In addition to the inverter's holding function, install a holding device to ensure safety.

!Before running an inverter which had been stored for a long period, always perform inspection and test operation.

(5)Emergency stop

CAUTION

!Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

(6)Maintenance, inspection and parts replacement

CAUTION

!Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.

(7)Disposing of the inverter

CAUTION

!Treat as industrial waste.

(8)General instructions

Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially open. Never run the inverter like this. Always replace the cover and follow this instruction manual when operating the inverter.
