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. 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.
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.
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.

PROTECTIVE FUNCTIONS z To know the operating status at the occurrence of an alarm When any alarm has occurred, the display automatically switches to the indication of the corresponding protective function (error). By pressing the [MODE] key at this point without resetting the inverter, the display shows the output frequency.
PROTECTIVE FUNCTIONS 5.1.3 Alarm code output By setting Pr. 76 "alarm code output selection", an alarm definition can be output as a 4-bit digital signal. This signal is output from the open collector output terminals equipped as standard on the inverter. Correlations between alarm definitions and alarm codes are as follows.
5.2 Troubleshooting PROTECTIVE FUNCTIONS 5.2 Troubleshooting If any function of the inverter is lost due to occurrence of a fault, clear up the cause and make correction in accordance with the following procedures. Contact your sales representative if the corresponding fault is not found below, the inverter has failed, parts have been damaged, or any other fault has occurred.
PROTECTIVE FUNCTIONS 5.2.2 Faults and check points POINT: Check the corresponding areas. If the cause is still unknown, it is recommended to initialize the parameters (return to factory settings), re-set the required parameter values, and check again.

5.3 Precautions for Maintenance and Inspection PROTECTIVE FUNCTIONS 5.3 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.
PROTECTIVE FUNCTIONS 5.3.4 Insulation resistance test using megger 1) 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.

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 tester alternately at the inverter terminals R, S, T, U, V, W, P and N 〈L , U, V, W, + and −〉, and check for continuity.
PROTECTIVE FUNCTIONS 5.3.6 Replacement of parts The inverter consists of many electronic parts such as semiconductor devices. The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced performance or failure of the inverter. For preventive maintenance, the parts must be changed periodically.
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.
PROTECTIVE FUNCTIONS 5.3.8 Measurement of main circuit voltages, currents and power 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. When instruments for commercial frequency are used for measurement, measure the following circuits using the instruments given on the next page.
