WARNI NG!

1. DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive

easily damage by high-voltage.

2. There are highly sensitive MOS components on the printed circuit boards. These components

are especially sensitive to static electricity. To prevent damage to these components, do not

touch these components or the circuit boards with metal objects or your bare hands.

3. Only qualified persons are allowed to install, wire and maintain AC motor drives.

CAUTION!

1. Some parameters settings can cause the motor to run immediately after applying power.

2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,

high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic

particles.

3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or

electric shock.

4. To prevent personal injury, please keep children and unqualified people away from the

equipment.

5. When the motor cable between AC motor drive and motor is too long, the layer insulation of the

motor may be damaged. Please use a frequency inverter duty motor or add an AC output

reactor to prevent damage to the motor. Refer to appendix B Reactor for details.

6. The rated voltage for AC motor drive must be ≤ 240V (≤ 480V for 460V models) and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models).

during power up. Please check the chart of Appendix B and select the correct fuse with rated current. Use of an NFB is optional.

Magnetic contactor (Optional)

Please do not use a Magnetic contactor as the I/O switch of the AC motor drive, as it will reduce the operating life cycle of the AC drive.

Used to improve the input power factor, to reduce harmonics and provide protection from AC line

disturbances (surges, switching Input AC Line Reactor (Optional)

spikes, short interruptions, etc.). AC

line reactor should be installed when

the power supply capacity is 500kVA

or more or advanced capacity is

activated .The wiring distance should

10m. Refer to appendix B for

≤

details.

Zero phase reactors are used to

Zero-phase Reactor (Ferrite Core Common Choke) (Optional)

reduce radio noise especially when

audio equipment is installed near the

inverter. Effective for noise reduction

on both the input and output sides.

Attenuation quality is good for a wide

range from AM band to 10MHz.

Appendix B specifies the zero phase

reactor. (RF220X00A)

EMI filter (Optional)

To reduce electromagnetic

interference, please refer to Appendix

B for more details.

Used to reduce the deceleration time

of the motor. Please refer to the chart

in Appendix B for specific Brake

Resistors.

breaker to 3-phase AC power (some models to 1-phase AC power) for circuit protection. It

is unnecessary to consider phase-sequence.

It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off



power quickly and reduce malfunction when activating the protection function of AC motor

drives. Both ends of the MC should have an R-C surge absorber.

Please make sure to fasten the screw of the main circuit terminals to prevent sparks



which is made by the loose screws due to vibration.

Please use voltage and current within the regulation shown in Appendix A.



When using leakage-current breaker to prevent leakage current,



Do NOT run/stop AC motor drives by turning the power ON/OFF. Run/stop AC motor



drives by RUN/STOP command via control terminals or keypad. If you still need to

run/stop AC drives by turning power ON/OFF, it is recommended to do so only ONCE per

hour.

Do NOT connect 3-phase models to a 1-phase power source.



Output terminals for main circuit (U, V, W)

When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor



terminals U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclockwise (as

viewed on the shaft end of the motor) when a forward operation command is received. To

permanently reverse the direction of motor rotation, switch over any of the two motor

leads.

Chapter 2 Installation and Wiring|

Forward running

DO NOT connect phase-compensation capacitors or surge absorbers at the output



terminals of AC motor drives.

With long motor cables, high capacitive switching current peaks can cause over-current,



high leakage current or lower current readout accuracy. To prevent this, the motor cable

should be less than 20m for 3.7kW models and below. And the cable should be less than

50m for 5.5kW models and above. For longer motor cables use an AC output reactor.

Use well-insulated motor, suitable for inverter operation.
