compliance with U.L. standards is a required.

CAUTION!

1. Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply may

result in damage to the equipment. The voltage and current should lie within the range as

indicated on the nameplate.

2. All the units must be grounded directly to a common ground terminal to prevent lightning strike

or electric shock.

3. 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.

4. Check following items after finishing the wiring:

A. Are all connections correct?

B. No loose wires? C. No short-circuits between terminals or to ground?

4. Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it

comes in contact with high voltage.

5. The AC motor drive, motor and wiring may cause interference. To prevent the equipment

damage, please take care of the erroneous actions of the surrounding sensors and the

equipment.

6. 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. To permanently reverse the direction of motor rotation,

switch over any of the two motor leads.

7. 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.

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-M 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-M 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.

Note: Use twisted-shielded, twisted-pair or shielded-lead wires for the control signal wiring. It is

recommended to run all signal wiring in a separate steel conduit. The shield wire should only be

connected at the drive. Do not connect shield wire on both ends.

Analog inputs (AVI, ACI)

Analog input signals are easily affected by external noise. Use shielded wiring and keep it as



short as possible (<20m) with proper grounding. If the noise is inductive, connecting the shield

to terminal GND can bring improvement.

If the analog input signals are affected by noise from the AC motor drive, please connect a



capacitor (0.1μF and above) and ferrite core as indicated in the following diagrams:

ferrite core

AVI /AC I

GND

wind each wires 3 times or more around the core

Digital inputs (M0~M5)

When using contacts or switches to control the digital inputs, please use high quality



components to avoid contact bounce.

Digital outputs (MO1)

Make sure to connect the digital outputs to the right polarity, see wiring diagrams.



When connecting a relay to the digital outputs, connect a surge absorber or fly-back diode



across the coil and check the polarity.

Revision May 2008, ME14, SW V3.04 2-11

Chapter 2 Installation and Wiring|

General

Keep control wiring as far away as possible from the power wiring and in separate conduits to



avoid interference. If necessary let them cross only at 90º angle.

The AC motor drive control wiring should be properly installed and not touch any live power



wiring or terminals.

NOTE

If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as



possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

DANGER!

Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it comes

in contact with high voltage.
