2.3 Other wiring 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 counter 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.

INSTALLATION AND WIRING • 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.

Install filter (FR-BLF,FR-BSF01) to inverter output side. FRBLF Inverter power supply Install filter FR-BIF to inverter input side. Separate inverter and power line 30cm (11.81inches) or more (at least 10cm (3.94inches)) from sensor circuit.
INSTALLATION AND WIRING (2) Line-to-line leakage currents Harmonics of leakage currents flowing in static capacities between the inverter output cables might operate the external thermal relay unnecessarily. When the wiring length is long (50m (164.04feet) or more) for the 400V class small-capacity model (7.5kW (10HP) or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.
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 Motor Output (kW (HP)) FR-F520-0.75K FR-F520-1.5K FR-F520-2.2K FR-F520-3.7K FR-F520-5.5K FR-F520-7.5K FR-F520-11K FR-F520-15K FR-F520-18.

PROTECTIVE FUNCTIONS 5.1.2 To know the operating status at the occurrence of an alarm When any alarm has occurred, the display automatically switches to the indication of the corresponding protective function (error). By pressing the MODE key at this point without resetting the inverter, the display shows the output frequency. In this way, it is possible to know the running frequency at the occurrence of the alarm. This also applies to the current.
PROTECTIVE FUNCTIONS 5.1.4 Alarm code output By setting Pr. 76 "alarm code output selection", an alarm definition can be output as a 4-bit digital signal. This signal is output from the open collector output terminals equipped as standard on the inverter. Correlations between alarm definitions and alarm codes are as follows.

5.3 Precautions for Maintenance and Inspection PROTECTIVE FUNCTIONS 5.3 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. 5.3.
PROTECTIVE FUNCTIONS 5.3.4 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.
PROTECTIVE FUNCTIONS Area of Inspection Inspection Item Inverter module, Converter module Main circuit Relay Resistor Control circuit Operation Proteccheck tive circuit Cooling system Cooling fan Display Description Interval Periodic* Daily 1 2 year years Check resistance across terminals. $ $ (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.
PROTECTIVE FUNCTIONS • Checking the inverter and converter modules 1) Disconnect the external power supply cables (R, S, T) 〈L1, L2, L3〉 and motor cables (U, V, W). 2) Prepare a meter. (Use 100Ω range.) Change the polarity of the tester alternately at the inverter terminals R, S, T, U, V, W, P and N 〈 L1, L2, L3, U, V, W, + and −〉, and check for continuity. Note: 1. Before measurement, check that the smoothing capacitor is discharged. 2.
PROTECTIVE FUNCTIONS 5.3.7 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 failure of the inverter. For preventive maintenance, the parts must be changed periodically. The part replacement guidelines for the inverter are indicated in the following table.
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. This is greatly influenced by the ambient temperature and operating conditions.
PROTECTIVE FUNCTIONS 5.3.9 Measurement of main circuit voltages, currents and power 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.
