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 or wiring 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.

CAUTION ! The electronic thermal reray function 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. Otherwise nearby electronic equipment may be affected.

INSTALLATION AND WIRING 2.3.3 Inverter-generated noise and reduction techniques Some noises enter the inverter causing it to incorrectly operate, 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 53
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.
Page 54
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 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-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other lines through the earth (ground) cable, etc.
INSTALLATION AND WIRING ! ! ! ! Countermeasures • Use the electronic thermal relay function of the inverter. • Decrease the carrier frequency. Note that motor noise increases. Selection of Soft- PWM will make it unoffending. To ensure that the motor is protected not to be influenced by line-to-line leakage currents, we recommend the protection method which uses a temperature sensor to directly detect motor temperature.

MAINTENANCE/INSPECTION 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.
MAINTENANCE/INSPECTION 6.1.4 Insulation resistance test using megger 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.
