Installation and enclosure design Installation and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter uses many semiconductor devices.
Installation and enclosure design Humidity Operate the inverter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown.
Installation and enclosure design Vibration, impact The vibration resistance of the inverter is up to 2.9 m/s at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, even if those vibration and impacts are within the specified values.

Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) 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 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 Selecting the rated sensitivity current for the earth leakage circuit breaker When using an earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency. •...
Electro-magnetic interference (EMI) and leakage currents NOTE • Install the earth leakage circuit breaker (ELB) on the input side of the converter unit. • In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
Electro-magnetic interference (EMI) and leakage currents 3.1.2 Countermeasures against inverter-generated 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.
Electro-magnetic interference (EMI) and leakage currents EMI countermeasure example Enclosure Decrease carrier frequency Install filter on inverter output side. Inverter Line noise Converter power Inverter Motor filter filter unit supply Use 4-core cable for motor Separate inverter, power cable and use one cable converter unit and as earth (ground) cable.
Electro-magnetic interference (EMI) and leakage currents 3.1.3 Converter unit (FR-CC2) built-in EMC filter The converter unit (FR-CC2) is equipped with a built-in EMC filter (capacitive filter). These filters are effective in reducing air-propagated noise on the input side of the converter unit. To enable the EMC filter, fit the EMC filter ON/OFF connector to the ON position.
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 supply harmonics 3.2.2 Harmonic Suppression Guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression Guidelines for Household Appliances and General-purpose Products"...

Checklist before starting operation Refer Check Checkpoint Countermeasure to page by user When performing frequent starts/stops by the inverter, rise/fall in the temperature of the transistor element of the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased A countermeasure is provided for an by reducing current at locked condition, starting current, etc.
Failsafe system which uses the inverter Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function activates and outputs a fault signal. However, a fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi 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.
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 signal (Y12 signal) is output when the inverter operates and current flows into the motor. Check if Y12 signal is being output while inputting a start signal to the inverter.
