INSTALLATION AND WIRING (6) Connection of the power regeneration converter (FR-RC) (For power coordination, always install the power factor improving reactor (FR-BAL).) When connecting the FR-RC type power regeneration converter, connect the inverter terminals (P/+, N/-) and FR-RC type power regeneration converter terminals as shown below so that their signals match with each other. After making sure that the wiring is correct, set "0" in Pr. 30 "regenerative function selection".
INSTALLATION AND WIRING 2.2.6 Design information 1) When performing commercial power supply-inverter switch-over operation, securely provide electrical and mechanical interlocks for MC1 and MC2 used for commercial power supply-inverter switch-over. When there is a commercial power supply-inverter switch-over circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switch-over or chattering caused by a sequence error.
INSTALLATION AND WIRING 2.3 Other wiring 2.3.1 Power harmonics Power harmonics may be generated from the converter section of the inverter, affecting power supply equipment, power capacitors, etc. Power harmonics are different in generation source, frequency and transmission path from radio frequency (RF) noise and leakage currents. Take the following measures.
INSTALLATION AND WIRING 2.3.2 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 3) Harmonic suppression technique requirement If the outgoing harmonic current is higher than the maximum value per 1kW (contract power) × contract power, a harmonic suppression technique is required. 4) Harmonic suppression techniques No. Item Description 1 Reactor installation (ACL, DCL) Install a reactor (ACL) in the AC side of the inverter or a reactor (DCL) in its DC side or both to suppress outgoing harmonic currents.
INSTALLATION AND WIRING 2.3.3 Inverter-generated noises and their reduction techniques Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction 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 inverters chops outputs at high carrier frequency, that could generate noise.
INSTALLATION AND WIRING Noise Path Measures 1) 2) 3) When devices that handle low-level signals and are liable to malfunction due to noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated noises. The following measures must be taken: (1) Install easily affected devices as far away as possible from the inverter.
INSTALLATION AND WIRING • Data line filter Noise entry can be prevented by providing a data line filter for the detector cable etc. • Data examples By decreasing the carrier frequency, the noise terminal voltage* can be reduced. Use Pr. 72 to set the carrier frequency to a low value (1kHz). Though motor noise increases at a low carrier frequency, selection of Soft-PWM in Pr. 240 will make it unoffending.
INSTALLATION AND WIRING 2.3.4 Leakage currents and countermeasures Leakage currents flow through static capacitances existing in the inverter I/O wiring and motor. Since their values depend on the static capacitances, carrier frequency, etc., take the following measures. (1) To-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other line through the earth (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. When the 400V class motor is driven by the inverter, consider the following measures.
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.
INSTALLATION AND WIRING (2) Selection of the rated sensitivity current for the earth (ground) leakage circuit breaker When using the earth (ground) leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independent of the carrier frequency setting: • Breaker for harmonic and surge: Rated sensitivity current: l∆n ≥ 10 × (lg1 + lgn + lg2 + lgm) • Standard breakers: Rated sensitivity current: l∆n ≥ 10 × {lg1 + lgn + 3 ( (lg2+lgm)} Example of leakage current per 1
INSTALLATION AND WIRING (3) Power-off and magnetic contactor (MC) On the inverter primary side, it is recommended to provide an MC for the following purposes (Refer to page 46 for selection.): 1)To release the inverter from the power supply when the inverter protective function is activated or the drive becomes faulty (e.g. emergency stop operation).
INSTALLATION AND WIRING 2.3.7 Instructions for compliance with U.S. and Canadian Electrical Codes (Standard to comply with: UL 508C) (1) Installation The FR-A500 is UL-listed as a product for use in an enclosure. Design an enclosure so that the ambient temperature, humidity and ambience of the inverter will satisfy the specifications. (Refer to page 223.

Check that the brake resistor is not connected to terminals P-P1 by mistake. 5.2.
CHAPTER 6 PRECAUTIONS FOR MAINTENANCE AND INSPECTION Chapter 1 This chapter provides the "precautions for maintenance and inspection" of this product. Always read the instructions and other information before using the equipment. Chapter 2 6.1 Precautions for maintenance and inspection ............
PRECAUTIONS FOR MAINTENANCE AND INSPECTION 6.1 Precautions for maintenance and inspection The transistorized inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to adverse influence by the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors. 6.1.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION 6.1.4 Insulation resistance test using megger 1) Before performing the insulation resistance test using a megger on the external circuit, disconnect the cables from all terminals of the inverter so that the test voltage is not applied to the inverter. 2) For the continuity test of the control circuit, use a meter (high resistance range) and do not use the megger or buzzer.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION Interval Area of Inspec -tion Main circuit Inspect ion Item Description Periodic Daily 1 year Inverter module, Convert er module Check resistance across terminals. { Relay (1) Check for chatter during operation. (2) Check for rough surface on contacts. (1) Check for crack in resistor insulation. (2) Check for open cable. { (1) Check balance of output voltages across phases with inverter operated alone.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION z Checking the inverter and converter modules (1) Disconnect the external power supply cables (R, S, T) and motor cables (U, V, W). (2) Prepare a tester. (Use 100Ω range.) Change the polarity of the tester alternately at the inverter terminals R, S, T, U, V, W, P and N, and check for continuity. Note: 1. Before measurement, check that the smoothing capacitor is discharged. 2.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION 6.1.7 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 fault of the inverter. For preventive maintenance, the parts must be replaced periodically. The part replacement guidelines for the inverter are indicated in the following table.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION (2) Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is also used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the ambient temperature and operating conditions.
PRECAUTIONS FOR MAINTENANCE AND INSPECTION 6.1.9 Measurement of main circuit voltages, currents and powers z Measurement of main circuit voltages, currents and powers Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments given on the next page.
