motor cable (output) are connected correctly. Otherwise, the inverter will be damaged.
3. Since the service life of the inverter is greatly affected by the ambient temperature of the installation location, it is
recommended to lower the ambient temperature before operation.
4. When installing the product in a control cabinet, check the cabinet size and ensure sufficient ventilation.
5. When the capacitors and surge suppressors used for improving the power factor are connected to the inverter’s output
terminal, the inverter may be heated or even damaged bacause of the high-order harmonic components. Therefore, do not
connect the capacitors and surge suppressors to the output terminal of the inverter. To increase the power factor, you can
install the DC reactor at the DC side or install the AC reactor at the primary side (i.e. input terminal) of the inverter.
6. When implementing a megger test, follow the method given in this instruction manual (10-4 “Megger Test”).
7. When using leakage circuit breaker protection switch, select a product for corresponding high-order harmonic and surge.
8. In principle, there is no magnetic contactor between the inverter and the motor. However, if the magnetic contactor is
turned ON and OFF while the inverter is operating, an excess current will be generated.
9. Select larger capacity since the operating characteristics of full electromagnetic-type MCCB changes with high-order
harmonic current.

4-2 About Wiring
◆Before carrying out wiring work, cut off the inverter’s input power supply, and make sure that no applied voltage
is present.
(1) Be sure to connnect a circuit breaker between the power supply and the input power supply terminals (R, S, T).
(Use a leakage circuit breaker specific to high-order harmonic when necessary.) To ensure the system safety,
connect a MC (electromagnetic contactor) between the circuit breaker and the input power supply.
(2) The phase order does not need to be considered when wiring the input power supply terminals (R, S and T).
(3) Connect the wires between the motor and the output terminals (U, V, W) correctly.
◆The high-order harmonic leakage current increases accordingly when the total length of wiring between inverter
and motor is too long, which causes adverse affects on peripheral devices.
The total length of wiring between inverter and motor shall not exceed the values described in Table 4-1.
Table 4-1 Length of wiring between the inverter and the motor
Length of wiring between the inverter
and the motor
50m 100m 200m
Carrier frequency
(Specified by F1009)
F1009=130 or less F1009=90 or less F1009=40 or less
● When driving several motors at the same time, the total length of wiring to motors shall not exceed the values described
in Table 4-1. However, for vector control, the maximum wiring length shall be controlled within 100m. (For length of
more than 30m, please implement auto detecting mode 2)
● The surge voltage generated by the inverter element switching is superimposed and added to the motor terminal voltage.
The following measures should be considered to prevent deterioration of motor isolation especially for 400V class motors
when the length of wiring between the inverter and the motor is long.
① Use motors with reinforced isolation.
② Shorten the length of wiring between the inverter and the motor as possible (Generally about 10 - 20m).
(4) Refer to 4-5-4 for capacity of MCCB and MC as well as the wire sizes.
Use sleeved crimp terminals for the power and motor cables.
(5) Use shielded or twisted-pair wires for wiring to the control circuit terminals, while keep the wires well away
from the main and high-voltage circuits (including logic circuit of 200 V relay).
(6) Use a micro-signal contact or two-contact relay for the control circuit terminal to prevent poor contact.
(7) Ground the ground terminal ( ) securely.(Never use the casing or the chassis.)
According to technical standards for electrical equipment, 400V series shall be connected to the grounding
electrode for type C grounding.
Table 4-2 Types of grounding
Voltage Types of grounding Grounding resistance
400V series Type C grounding 10Ωor less
● Do not share the grounding wire with the welding machine or the power equipment.
● Use the grounding wire prescribed in the technical standards for electrical equipment, and shorten wiring length as much as
possible.
● Be careful not to loop the grounding wire when using multiple inverters.

- 14 -
(8) During wiring, please note that the inside of inverter shall be free from chips of wires.
◆Control circuit wiring precautions
yUse shielded cable for analog input and output cables as well as the contact input cable (digital multifunctional input
terminals).
yTo prevent misoperation due to interfenrence, the signal cables and power cables should be separated as possible during the
wiring (above 10cm).
yWhen using the operation panel for running, it can be realized only through the main circuit wiring (Without the need to
operate from the outside or by inputting frequency instructions).
yConnect the MCCB (circuit breaker) and other circuit protectors between the power supply and the input terminals.
yWhen the protective function of the inverter is enabled or the occurrence of other accidents, please connect the MC
(electromagnetic contactor) between MCCB and input terminals to cut off the inverter power supply, preventing further
expansion of failure or accident. Furthermore, the MC should be connected as close to the inverter as possible.

※1 The above brake resistor is selected by assuming the maximum duty cycle to be 10% ED. When % ED needs to be set above
10%, brake resistor capacity should be increased proportionally.
Example) When setting 20 % ED, the capacity should be doubled that of 10%ED.

Notes: The values for wires in the main circuit are for 600 V IV PVC-insulated wires (60ºC) when the inverter ambient
temperature is 40ºC. The values in parentheses are for 600 V bridged-polyethylene insulated wires (90ºC). The maximum
wire size indicates the maximum wire cross-sectional area that can be used with the terminal block.
