maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the following

safety guidelines before connecting power to the AC motor drive. Keep this operating manual at hand

and distribute to all users for reference.

To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor

drive are to do installation, start-up and maintenance. Always read this manual thoroughly before

using VFD-G series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.

Failure to comply may result in personal injury and equipment damage. If you have any questions,

please contact your dealer.

PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

DANGER!

1. AC input power must be disconnected before any wiring to the AC motor drive is made.

2. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power

has been turned off. To prevent personal injury, please ensure that power has been turned off

before opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe

voltage levels.

3. Never reassemble internal components or wiring.

4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the

input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and

W/T3 directly to the AC mains circuit power supply.

5. Ground the VFD-G using the ground terminal. The grounding method must comply with the

laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring

Diagram.

6. VFD-G series is used only to control variable speed of 3-phase induction motors, NOT for 1-

phase motors or other purpose.

7. VFD-G series shall NOT be used for life support equipment or any life safety situation.

WARNI NG!

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

drive is easily damaged by high-pressure.

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 parameter settings will 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 the 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 the AC motor drive must be ≤ 480V for 460V models and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models).

8. The AC motor drive, electric welding machine and the greater horsepower motor should be

grounded separately.

9. Use ground leads that comply with local regulations and keep them as short as possible.

10. No brake resistor is built in the VFD-G series, it can install brake resistor for those occasions

that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11. Multiple VFD-G units can be installed in one location. All the units should be grounded directly

to a common ground terminal, as shown in the figure below. Ensure there are no ground

loops.

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 phase lead reactor will be switched.

And the mains wiring distance

Please refer to Appendix B for more

details.

Zero phase reactors are used to

Zero-phase Reactor (Ferrite Core Common

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)

Brake Resistor (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.

Motor surge voltage amplitude Output AC Line Reactor (Optional)

depends on motor cable length. For

applications with long motor cable

(>20m), it is necessary to install a

reactor at the inverter output side.

10m.
