Page 49: Noise And Leakage Currents
Noise and leakage currents 3.1 Noise and leakage currents 3.1.1 Leakage currents and countermeasures 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 capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.

Page 51: Inverter-Generated Noises And Their Reduction Techniques
Noise and leakage currents 3.1.2 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 noises, it handles low-level signals, so it requires the following basic techniques.
Page 52 Noise and leakage currents Noise Propagation Measures Path 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.
Page 53: Power Supply Harmonics
Noise and leakage currents 3.1.3 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Page 54: Harmonic Suppression Guideline
Noise and leakage currents 3.1.4 Harmonic suppression guideline Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guideline was established to protect other consumers from these outgoing harmonic currents. The three-phase 200V input specifications 3.7kW or less are previously covered by "Harmonic suppression guideline for household appliances and general-purpose products"...
Page 55 Noise and leakage currents 1) Calculation of equivalent capacity P0 of harmonic generating equipment The "equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating equipment and is calculated with the following equation. If the sum of equivalent capacities is higher than the limit in Table 3, harmonics must be calculated with the following procedure: P0 = Σ...
Page 56 Noise and leakage currents 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 Item Description Reactor installation Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on (FR-HAL, FR-HEL) its DC side or both to suppress outgoing harmonic currents.
Page 57: Installation Of A Reactor
Installation of a reactor 3.2 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000kVA or more and wiring length 10m max.) or when a power capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit.
Page 58: Precautions For Use Of The Inverter
Precautions for use of the inverter 3.4 Precautions for use of the inverter The FR-B, B3 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
Page 59 Precautions for use of the inverter (12) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.

Measurement of main circuit voltages, currents and powers 6.2.3 Measurement of currents Use a moving-iron type meter on both the input and output sides of the inverter. However, when using the FR-B3 series low noise type, do not use that meter since an eddy-current losses produced in the internal metal parts of the meter will increase and the meter may burn out.
