Thank you for choosing the Mitsubishi Transistorized inverter. This instruction manual gives handling information and precautions for use of this equipment. Incorrect handling might cause an unexpected fault. Before using the inverter, please read this manual carefully to use the equipment to its optimum. Please forward this manual to the end user.
SAFETY INSTRUCTIONS 1. Electric Shock Prevention WARNING While power is on or when the inverter is running, do not open the front cover. You may get an electric shock. Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
3. Injury Prevention CAUTION Apply only the voltage specified in the instruction manual to each terminal to prevent damage etc. Ensure that the cables are connected to the correct terminals. Otherwise, damage etc. may occur. Always make sure that polarity is correct to prevent damage etc. While power is on and for some time after power-off, do not touch the inverter or brake resistor as they are hot and you may get burnt.
( 2 ) Wiring CAUTION Do not fit capacitive equipment such as a power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter. The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.
CAUTION When a 400V class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. Surge voltages attributale to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. When parameter clear or all clear is performed, each parameter returns to the factory setting.

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.
2.3 Other Wiring INSTALLATION AND WIRING 2.3 Other Wiring 2.3.1 Power supply harmonics Power supply harmonics may be generated from the converter section of the inverter, affecting the power supply equipment, power capacitor, etc. Power supply harmonics are different in generation source, frequency band and transmission path from radio frequency (RF) noise and leakage currents.
INSTALLATION AND WIRING 2.3.2 Japanese 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. 1) "Harmonic suppression guideline for household appliances and general-purpose products"...
INSTALLATION AND WIRING 3) Measures against noises which are radiated by the inverter causing misoperation of peripheral devices. Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuit (I/O), those electromagnetically and electrostatically inducted to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.
INSTALLATION AND WIRING Noise Path Measures When devices which handle low-level signals and are susceptible to misoperation due to noise (such as instruments, receivers and sensors) are installed near the inverter and their signal cables are contained in the same panel as the inverter or are run near the inverter, the devices may be misoperated by air-propagated noise and the following measures must be taken: (1) Install easily affected devices as far away as possible from the...
INSTALLATION AND WIRING z Data line filter Noise entry can be prevented by providing a data line filter for the detector or other cable. z Data examples By using shielded cables as signal cables, By decreasing the carrier frequency, the induction noise can be reduced greatly (1/10 to noise terminal voltage* can be reduced.
INSTALLATION AND WIRING 2.3.4 Leakage currents and countermeasures Due to the static capacitance existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitance, carrier frequency, etc., take the following measures. ( 1 ) To-ground leakage currents Leakage currents may flow not only into the inverter's own line but also into the other lines through the ground cable, etc.
INSTALLATION AND WIRING z Countermeasures y Use the electronic overcurrent protection of the inverter. y Decrease the carrier frequency. Note that motor noise increases. Selection of Soft-PWM will make it unoffending. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.
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.

PROTECTIVE FUNCTIONS z Checking the inverter and converter modules <Preparation> (1)Disconnect the external power supply cables (R, S, T (L )) and motor cables (U, V, W). (2)Prepare a meter. (Use 100Ω range.) <Checking method> Change the polarity of the meter alternately at the inverter terminals R (L ), S (L T (L ), U, V, W, P (+) and N (−), and check for continuity.
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 structural or physical characteristics, leading to reduced performance or failure of the inverter. For preventive maintenance, the parts must be changed periodically.
PROTECTIVE FUNCTIONS (For the FR-E540-1.5K to 7.5K-NA) 1) Remove the front cover (Refer to page 5.). 2) Unplug the fan connector. The cooling fan is connected to the cooling fan connector beside the main circuit terminal block of the inverter. Unplug the connector.
PROTECTIVE FUNCTIONS z Reinstallation (For the FR-E520-0.75K to 7.5K-NA) 1) After confirming the orientation of the fan, reinstall the fan to the cover so that the arrow on the left of "AIR FLOW" faces in AIR FLOW the opposite direction of the fan cover. Note: If the air flow is set in the wrong direction, the inverter life can be shorter.

Note: If the air flow is set in the wrong direction, the inverter life can be shorter.
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. When the inverter is operated in an ordinary, air-conditioned environment, change the capacitors about every 5 years.
PROTECTIVE FUNCTIONS 5.3.8 Measurement of main circuit voltages, currents and powers z 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.
PROTECTIVE FUNCTIONS Measuring Points and Instruments Measuring Remarks Item Measuring Point Instrument (Reference Measured Value) Power supply Is the commercial power supply Across R-S (L ), S-T (L Moving-iron type AC voltage within permissible variation of AC ) and T-R (L voltmeter (V1) voltage (refer to page 188).
PROTECTIVE FUNCTIONS Note: 1. Use FFT to measure the output voltage accurately. It can not be measured accurately with a meter or general instrumentation. 2. When the carrier frequency exceeds 5kHz, do not use the instrument because overcurrent losses occurring in the metallic parts inside the instrument will increase and may lead to burnout.
