Take the following measures.
INSTALLATION AND WIRING 2.3.2 Japanese harmonic suppression guidelines Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guidelines were established to protect other consumers from these outgoing harmonic currents.

INSTALLATION AND WIRING 2.3.3 Inverter-generated noises and reduction techniques Some noises enter the inverter causing it to misoperate and others are radiated by the inverter causing misoperation of peripheral devices. Though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following basic measures to be taken. Also, since the inverter chops the output at a high carrier frequency, it could generate noise.

FRBIF Separate inverter and power line 30cm (11.81 inches) or more (at least 10cm (3.94 inches)) from sensor circuit.
INSTALLATION AND WIRING 2.3.4 Leakage currents and countermeasures Due to the static capacitance existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitance, carrier frequency, etc., take the following measures. (1) To-ground leakage currents Leakage currents may flow not only into the inverter's own line but also into the other line through the ground cable, etc.
INSTALLATION AND WIRING 2.3.5 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation.
INSTALLATION AND WIRING 2.3.6 Peripheral devices (1) Selection of peripheral devices Check the capacity of the motor to be used with the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity. Refer to the following list and prepare appropriate peripheral devices: 1) 200V class Inverter Type FR-A520-0.4K FR-A520-0.75K FR-A520-1.5K FR-A520-2.2K FR-A520-3.7K FR-A520-5.5K FR-A520-7.5K FR-A520-11K FR-A520-15K FR-A520-18.

PROTECTIVE FUNCTIONS 5.3.6 Replacement of parts The inverter consists of many electronic parts such as semiconductor devices. The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced performance or failure of the inverter. For preventive maintenance, the parts must be changed periodically. (1) Cooling fan The cooling fan cools heat-generating parts such as the main circuit semiconductor devices.
PROTECTIVE FUNCTIONS (2) Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing the DC in the main circuit, and an aluminum electrolytic capacitor is also used for stabilizing the control power in the control circuit. Their characteristics are adversely affected by ripple current, etc. When the inverter is operated in an ordinary, airconditioned environment, change the capacitors about every 5 years.
PROTECTIVE FUNCTIONS 5.3.8 Measurement of main circuit voltages, currents and power z Measurement of voltages and currents Since the voltages and currents on the inverter power supply and output sides include harmonics, accurate measurement depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits using the instruments given on the next page.
PROTECTIVE FUNCTIONS Measuring Points and Instruments Item Power supply voltage V1 Power supply side current I1 Power supply side power P1 Power supply side power factor Pf1 Measuring Point Across R-S, S-T and T-R 〈Across L1-L2, L2-L3 and L3-L1〉 Measuring Instrument Moving-iron type AC voltmeter Remarks (Reference Measured Value) * Commercial power supply Within permissible AC voltage fluctuation R, S and T line currents Moving-iron type AC ammeter 〈L1, L2 and L1 line currents〉 At R, S and T, and acros

APPENDICES Appendix 3 Operating the Inverter Using a Single-Phase Power Supply Appendix 3 Operating the Inverter Using a Single-Phase Power Supply If a single-phase power supply is used to operate the inverter only 4 of the 6 of the diodes will be used. Therefore the ripple current of the capacitor will increase when compared to operation from a three-phase power supply, resulting in a higher temperature rise of the converter and the capacitor.
