PRECAUTIONS FOR USE OF THE INVERTER This chapter explains the precautions for use of this product. Always read the instructions before using the equipment. 3.1 Electro-magnetic interference (EMI) and leakage currents ..54 3.2 Power supply harmonics ............57 3.3 Installation of a reactor ............57 3.4 Power-OFF and magnetic contactor (MC) ......58...
Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) and leakage currents 3.1.1 Leakage currents and precautions Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Electro-magnetic interference (EMI) and leakage currents 3.1.2 Precautions against inverter-generated EMI Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
Electro-magnetic interference (EMI) and leakage currents Noise Countermeasure propagation path When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or the converter unit, or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.
Power supply harmonics Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Power-OFF and magnetic contactor (MC) Power-OFF and magnetic contactor (MC) Converter unit input side magnetic contactor (MC) On the converter unit input side, it is recommended to provide an MC for the following purposes: (Refer to page 14 for selection.) •...
Precautions against deterioration of the 600 V class motor insulation NOTE • Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open.
Checklist before starting operation Checklist before starting operation The FR-A860 series inverter and FR-CC2 converter unit are highly reliable products, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the products.

Although Mitsubishi Electric assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
Failsafe system which uses the inverter (d) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal The Output current detection (Y12) signal is output when the inverter operates and current flows into the motor. Check if the Y12 signal is being output while inputting a start signal to the inverter.

Inspection item Replacement procedure of the cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the cooling fan must be replaced immediately.
Inspection item Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the DC section of the main circuit, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit.
