This Instruction Manual (Basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (Basic) to the end user.
4. Additional Instructions Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.
This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the inverter until you have read through this Instruction Manual (Basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual (Basic), the safety instruction levels are classified into "WARNING" and "CAUTION".
Incorrect handling may cause hazardous conditions, resulting in death or severe injury. Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.
The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.
1.Electric Shock Prevention
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
Even if power is OFF, do not remove the front cover except for wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
Before wiring, inspection or switching EMC filter ON/OFF connector, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.
This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.
Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.
Setting dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
Do not replace the cooling fan while power is ON. It is dangerous to replace the cooling fan while power is ON.
Do not touch the printed circuit board or handle the cables with wet hands. Otherwise you may get an electric shock.
When measuring the main circuit capacitor capacity (Pr. 259 Main circuit capacitor life measuring = "1"), the DC voltage is applied to the motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.
IPM motor is a synchronous motor with high-performance magnets embedded in the rotor. Motor terminals hold high- voltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. When the motor is driven by the load in applications such as fan and blower, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.
WARNING
CAUTION
CAUTION
WARNING
2. Fire Prevention Inverter must be installed on a nonflammable wall without holes
(so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.
If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current could cause a fire.
Do not connect a resistor directly to the DC terminals P/+ and N/ -. Doing so could cause a fire.
Daily and periodic inspections must be performed as instructed in the Instruction Manual. If the product is used without receiving any inspection, it may cause a burst, break, or fire.
3. Injury Prevention The voltage applied to each terminal must be the ones specified in
the Instruction Manual. Otherwise burst, damage, etc. may occur. The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur. Polarity must be correct. Otherwise burst, damage, etc. may
occur. While power is ON or for some time after power-OFF, do not
touch the inverter since the inverter will be extremely hot. Doing so can cause burns.
(1) Transportation and installation
The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.
Do not stack the boxes containing inverters higher than the number recommended.
The product must be installed to the position where withstands the weight of the product according to the information in the Instruction Manual.
Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.
When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.
Do not stand or rest heavy objects on the product. The inverter mounting orientation must be correct. Foreign conductive objects must be prevented from entering the
inverter. That includes screws and metal fragments or other flammable substance such as oil.
As the inverter is a precision instrument, do not drop or subject it to impact.
The inverter must be used under the following environment: Otherwise the inverter may be damaged.
*1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s2 or less for the 185K or higher.
If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before packaging the product.

(2) Wiring Do not install a power factor correction capacitor, surge
suppressor or capacitor type filter on the inverter output side. These devices on the inverter output side may be overheated or burn out.
The connection orientation of the output cables U, V, W to the motor affects the rotation direction of the motor.
IPM motor terminals (U, V, W) hold high-voltage while the IPM motor is running even after the power is turned OFF. Before wiring, the IPM motor must be confirmed to be stopped. Otherwise you may get an electric shock.
Never connect an IPM motor to the commercial power supply. Applying the commercial power supply to input terminals (U,V, W) of an IPM motor will burn the IPM motor. The IPM motor must be connected with the output terminals (U, V, W) of the inverter.
(3) Test operation and adjustment
Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.
(4) Operation The IPM motor capacity must be same with the inverter capacity.
(The 0.75K inverter can be used with a one-rank lower MM-EF motor.)
Do not use multiple IPM motors with one inverter. Any person must stay away from the equipment when the retry
function is set as it will restart suddenly after trip.
Sincepressing key may not stop output depending on the
function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.
OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter alarm with the start signal ON restarts the motor suddenly.
Do not use an IPM motor in an application where a motor is driven by its load and runs at a speed higher than the maximum motor speed.
A dedicated IPM motor must be used under IPM motor control. Do not use a synchronous motor, induction motor, or synchronous induction motor under IPM motor control.
The inverter must be used for three-phase induction motors or the dedicated IPM motor. Connection of any other electrical equipment to the inverter output may damage the equipment.
Do not modify the equipment. Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the inverter.
CAUTION
CAUTION
WARNING
The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise the life of the inverter decreases.
The effect of electromagnetic interference must be reduced by using a noise filter or by other means. Otherwise nearby electronic equipment may be affected.
Appropriate measures must be taken to suppress harmonics. Otherwise power supply harmonics from the inverter may heat/ damage the power factor correction capacitor and generator.
When driving a 400V class motor by the inverter, the motor must be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations because all parameters return to the initial value.
The inverter can be easily set for high-speed operation. Before changing its setting, the performances of the motor and machine must be fully examined.
Stop status cannot be hold by the inverter's brake function. In addition to the inverter's brake function, a holding device must be installed to ensure safety.
Before running an inverter which had been stored for a long period, inspection and test operation must be performed.
Static electricity in your body must be discharged before you touch the product. Otherwise the product may be damaged.
Do not connect an IPM motor under the general-purpose motor control settings (initial settings). Do not use a general-purpose motor under the IPM motor control settings. Doing so will cause a failure.
In the system with an IPM motor, the inverter power must be turned ON before closing the contacts of the contactor at the output side.
(5) Emergency stop A safety backup such as an emergency brake must be provided
to prevent hazardous condition to the machine and equipment in case of inverter failure.
When the breaker on the inverter input side trips, the wiring must be checked for fault (short circuit), and internal parts of the inverter for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.
When any protective function is activated, appropriate corrective action must be taken, and the inverter must be reset before resuming operation.
(6) Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.
(7) Disposing of the inverter
The inverter must be treated as industrial waste.
General instructions Many of the diagrams and drawings in this Instruction Manual (Basic) show the inverter without a cover or partially open for explanation. Never operate the inverter in this manner. The cover must be always reinstalled and the instruction in this Instruction Manual (Basic) must be followed when operating the inverter. For more details on a dedicated IPM motor, refer to the Instruction Manual of the dedicated IPM motor.

2 INSTALLATION AND WIRING
CAUTION Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. This will
cause the inverter to trip or the capacitor, and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them.
Electromagnetic wave interference The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize interference. (Refer to Chapter 2 of the Instruction Manual (Applied).)
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices. An IPM motor cannot be driven by the commercial power supply. An IPM motor is a motor with permanent magnets embedded inside. High-voltage is generated at the motor terminals while the
motor is running even after the inverter power is turned OFF. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is stopped.

Devices connected to the output
Use within the permissible power supply specifications of the inverter.
The regeneration braking capability of the inverter can be exhibited fully. Install this as required.
Install the magnetic contactor to ensure safety. Do not use this MC to frequently start and stop the inverter. Doing so will cause the inverter life to be shortened.
The inverter can be connected with a computer such as a programmable controller and with GOT (human machine interface). They support Mitsubishi inverter protocol and Modbus-RTU (binary) protocol.
Do not install a power factor correction capacitor, surge suppressor or EMC filter (capacitor) on the output side of the inverter. When installing a moulded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the moulded case circuit breaker.
Power supply harmonics can be greatly suppressed. Install this as required.
Greater braking capability is obtained. Install this as required.
The breaker must be selected carefully since an inrush current flows in the inverter at power on.
Install an EMC filter (ferrite core) to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 0.5MHz to 5MHz. A wire should be wound four turns at a maximum.
