PRECAUTIONS FOR USE OF THE INVERTER This chapter explains the "PRECAUTIONS FOR USE OF THE INVERTER" for use of this product. Always read the instructions before using the equipment 2.1 Panel design ............24 2.2 Precautions for use of the inverter ......28 2.3 Others ..............29...
Panel design 2.1 Panel design When an inverter panel is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the panel structure, size and equipment layout.
Panel design (3) Dust, dirt, oil mist Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to moisture absorption of accumulated dust and dirt, and in-panel tempearture rise due to clogged filter. In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.
Panel design 2.1.2 Cooling system types for inverter panel From the panel that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-panel temperature lower than the permissible temperatures of the in-panel equipment including the inverter.
Panel design 2.1.3 Inverter placement (1) Clearances around the inverter To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter. At least the following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space.
Precautions for use of the inverter 2.2 Precautions for use of the inverter The FR-F700 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.
Others 2.3 Others 2.3.1 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.
Others (3) Selection of rated sensitivity current of earth (ground) leakage breaker When using the earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency: ⋅ Breaker designed for harmonic and surge suppression Example of leakage current Leakage current example of Rated sensitivity current:...
Others 2.3.2 Power-off and magnetic contactor (MC) (1) Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes. Refer to page 3 for selection.)) 1) To release the inverter from the power supply when the inverter's protective function is activated or when the drive is not functioning (e.g.
Others 2.3.4 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.
Others 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.
Others 2.3.5 EMC filter The inverter is equipped with a built-in EMC filter. Effective for reduction of air-propagated noise on the input side of the inverter. The EMC filter is factory-set to enable (ON). To disable it, fit the EMC filter ON/OFF connector to the OFF position. 00023 to 00126 00023 to 00126 00170, 00250...
Others 2.3.6 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. Take the following countermeasure suppression techniques. The differences between harmonics and noises are indicated below: Item Harmonics...
Others 2.3.7 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: Measures It is recommended to take either of the following measures:...

Reset method of protective function 4.3 Reset method of protective function (1) Resetting the inverter The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter. It takes about 1s for reset.
Meters and measuring methods 4.5 Meters and measuring methods Since voltages and currents in the primary and secondary side of the inverter include harmonics, different meters indicate different measurement values. When making measurement with the meters designed for commercial frequency, use the following measuring instruments and circuits: When installing meters etc.
Meters and measuring methods 4.5.2 Measurement of voltages and use of PT (1) Inverter input side As the input side voltage has a sine wave and it is extremely small in distortion, accurate measurement can be made with an ordinary AC meter. (2) Inverter output side Since the output side voltage has a PWM-controlled rectangular wave, always use a rectifier type voltmeter.
Meters and measuring methods 4.5.4 Use of CT and transducer A CT may be used in both the input and output sides of the inverter, but the one used should have the largest possible VA ability because an error will increase if the frequency gets lower. When using a transducer, use the effective value calculation type which is immune to harmonics.
