Thank you for choosing this 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.
Page 3: Safety Instructions
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.
Page 4 4. Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc.: (1) Transportation and installation CAUTION When carrying products, use correct lifting gear to prevent injury. Do not stack the inverter boxes higher than the number recommended. Ensure that installation position and material can withstand the weight of the inverter.
Page 5 CAUTION The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the equipment. The electronic overcurrent protection does not guarantee protection of the motor from overheating. Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Use a noise filter to reduce the effect of electromagnetic interference.

Page 44: Inverter-Generated Noises And Reduction Techniques
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.
Page 45 INSTALLATION AND WIRING Telephone Sensor power supply verter Instrument Receiver Sensor Motor 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 affected by air-propagated noises and the following measures must be taken: (1) Install easily affected devices as far away as possible from the inverter.
Page 46 INSTALLATION AND WIRING • • • • Data line filter Noise entry can be prevented by providing a data line filter for the detector cable etc. • • • • Data examples By decreasing the carrier frequency, the noise terminal voltage* can be reduced.
Page 47: Leakage Currents And Countermeasures
Note that motor noise increases. Selection of Soft-PWM (Pr. 240) will make it unoffending. ⋅ By using earth leakage circuit breakers designed for harmonic and surge suppression (e.g. Mitsubishi's Progressive Super Series) in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise).

Page 54: Earthing (Ec Version)
INSTALLATION AND WIRING 2.3.9 Earthing (EC version) ( 1 ) Earthing and Earth Leakage Current (a) Purpose of Earthing Electrical equipment usually has an Earthing Terminal, this must be connected to earth before using equipment. For protection, electric circuits are normally housed inside an insulated case. However it is impossible to manufacture insulating materials that prevent all current from leaking across them, therefore it is the function of the earth (safety earth) to prevent electric shocks when touching the case.
Page 55 INSTALLATION AND WIRING c) The safety earth should be as thick as possible, minimum thickness as stated in below table. d) The earthing point should be as close to the inverter as possible, and the wire as short as possible. e) The RFI earth should be a braided strap with a 10mm minimum cross sectional area, and as short as possible.

Page 241: Appendix 2 Operating The Inverter Using A Single-Phase Power Supply
Appendix 2 Operating the Inverter Using a Single-Phase Power Supply APPENDICES Appendix 2 Operating the Inverter Using a Single-Phase Power Supply If a single-phase power supply is used to operate the inverter only 4 of the 6 of the diodes will be used. Therefore the ripple current of the capacitor will increase when compared to operation from a three-phase power supply, resulting in a higher temperature rise of the converter and the capacitor.
