Safety Precautions

Precautions that must be heeded in order to protect the user and others from harm and prevent property loss or damage are as follows:

■The extent of injury or damage that could be suffered by improper use contrary to directions is ranked and explained as follows:

DANGER	Situation involving danger which could result in death or serious
	injury if equipment is handled incorrectly.
CAUTION	Situation involving danger which could result in medium to light
	injury, or property damage if equipment is handled incorrectly.

Items labeled as CAUTION could be connected with core serious consequences, depending upon the circumstances. In any case, these instructions are extremely important and should be observed in all cases.

■ Installation

CAUTION

●Install on non-combustible material such as metal.

Failure to do so could result in fire.

●Do not locate near combustibles.

Doing so could result in fire.

●Do not carry by the front case when moving the inverter.

Doing so is dangerous and could result in injury if dropped.

●Do not allow foreign material such as metal chips to get inside the inverter. Doing so could result in fire.

●Be sure to install on a base capable of supporting the inverter’s weight in accordance with the directions giving in the instruction manual.

Doing so is dangerous and could result in injury if dropped.

Safety Precautions

■ Wiring

DANGER

●Make sure the power is cut off before handling wiring. Failure to do so could result in electrical shock or fire.

●Be sure to install a no-fuse breaker (NFB).

Failure to do so could result in fire.

●Be sure to ground the GND terminal.

Failure to do so could result in electrical shock or fire.

●Have wiring work done by an electrician.

Failure to do so could result in electrical shock or fire.

●Be sure to install the inverter before wiring.

Failure to do so could result in electrical shock or fire.

CAUTION

●Do not connect the AC power source with the output terminals (U/L1, V/L2, W/L3).

Doing so could result in injury or fire.

●Make sure the voltage of the AC power source agrees with the rated voltage of the inverter.

If not, it could result in injury or fire.

Safety Precautions

■ Operation

DANGER

●Be sure to mount the case and cover before turning the power on. Never remove the case or cover while the inverter is receiving power.

Failure to mount or removing the case/cover could result in electric shock.

●The operator should secure the area before turning the power on or off. Failure to do so could result in injury.

●Never operate the switches with wet hands.

Doing so could result in electric shock.

●Never touch the terminals of the inverter when it is charged with power, even when it is not running. Doing so could result in electric shock.

●If the retry function is selected, the inverter could unexpectedly start operating again if tripped. Do not approach the inverter in the condition.

Doing so could result in injury.

●If trip reset is carried out with the operate signal ON, the inverter could unexpectedly start operating again. Do not approach the inverter in the condition. Doing so could result in injury.

CAUTION

●The radiator and regenerative resistor become very hot.

Touching these parts could result in skin burning injury.

●It is very easy to set speed from "low" to "high" by an inverter. Set the operating speed so that it the motor and machine tolerance is not exceeded.

Failure to do so could result in injury.

Safety Precautions

■Maintenance/inspection

DANGER

●Wait for at least 5 minutes after turning off the power to perform inspections. Failure to do so could result in electric shock.

●Maintenance and inspection should not be performed by anyone except a specialist.

The repairman should remove all metallic objects (watch, rings, etc.) before performing maintenance or inspection.

Use only insulated tools when performing maintenance or inspection. Failure to do so could result in electric shock or injury.

■Other

DANGER

●Absolutely DO NOT modify the inverter in any way.

Doing so could result in electric shock, injury or fire.

GENERAL PRECAUTIONS

The diagrams given in this instruction manual may show the cases, covers or safety breakers removed in order to show details.

When operating, be sure to return the cases, covers or safety breakers and operate as specified in the manual.

Precautions

Note the following precautions in order to use the inverter properly.

1.Arrange for the power source capacity to be between 1.5 to 500kVA the inverter's capacity. An excessively high peak current may flow to the power input circuit, and damage the converter section if the wiring length is short with a power source exceeding 500kVA, or the phase-advancing capacitor is switched on the power source side. In this case, provide individual power factor-enhancing AC reactors that match the inverter's capacity on the inverter input side.

2.Do not connect the phase-advancing capacitor to the output side of the inverter. Doing so could result in damage to the phase-advancing capacitor.

3.Do not provide a magnetic contactor between the inverter and motor. To run or turn the motor on/off, use the RUN switch on the control panel or the control input terminal.

Avoid frequently turning the magnetic contactor, provided on the power source, on and off.

4.Operating the motor by the inverter could increase leakage current and trip the earth leakage breaker. In this case, use earth leakage breakers designed for high frequency for this system and other systems.

5.Take the following precautions if using a built-in electronic thermal relay contained in the inverter:

Check the rated current of your 3-phase induction motor, and set the appropriate electronic thermal value.

Use one motor for each inverter.

6.in using the inverter to drive multiple motors connected in parallel, select an inverter of a capacity that does not exceed the total rated current of the inverter. When calculating by total output of the motor, the inverter’s rated current may be exceeded, depending on the type of motor.

7.The total wiring length between inverter and motor should not exceed 30 meters. If the wiring is to be longer than this, you should provide a reactor, etc., between inverter and motor.

8.Install the inverter securely to avoid injuries in the case of an earthquake.

9.Before running the inverter following an earthquake, check installation of the inverter and motor and make sure they are safe to operate.

The common terminal used for contact input of external power is used. When power is on (PLC and G connected), a closed terminal in ON, and an open one, OFF

Frequency can be set when 0 ~ +5VDC (or 0 - +10VDC) is input between “FIN1” and “G”, or 4-20mA between "FIN2"-G. If both are input, the bigger will be pick up.

If using these terminals, change “frequency command” to or .

Common ground terminal for contact input. The common terminal used for contact input of synchronized input is used. When power is on (PLC and 12V connected), a closed terminal in ON, and an open one, OFF.

Outputs voltage proportional to output frequency between “FOUT” and “G.” Connect full-scale 1 mA DC ammeter. You can output pulses synchronized with output frequency by altering “FOUT switch”.

Forward by shorting between “I1” and “G”; stop by release Reverse by shorting between “I2” and “G”; stop by release

System Configuration and Wiring

Precautions when wiring

Main circuit

(1)The inverter will be damaged if you invert the connections of the power input terminal and motor output terminal (U/L1, V/L2 ... W/L3). Absolutely do not invert connections.

(2)Do not ground the main circuit terminal.

(3)Do not short motor output terminals (U/L1, V/L2 ... W/L3) together.

(4)The GND terminal (E) is the frame ground (FG) for the inverter.

(5)Be sure to use insulated crimp terminals for connecting to the main circuit terminals.

Control circuit

(1)Do not apply more than 24VDC, 50mA to the output terminals (O1, O2, COM1), or apply voltage to terminal in reverse.

(2)Input terminal configuration is shown in the following figure.

You can control by contact or by open collector output. Do not apply external voltage.

Internal circuits are as follows:

Photo coupler

I1 I6

GND

Inverter internal power source +12V

(3)Do not short the frequency setting power source terminal (5V) and ground for control terminal (G).

(4)To directly drive the relay by the output terminals (O1, O2, COM), mount a flywheel diode (FD).
