to retain the warranty coverage, the AC motor drive should be stored properly when it is not to
be used for an extended period of time. Storage conditions are:

CAUTION!

1. Store in a clean and dry location free from direct sunlight or corrosive fumes.

2. Store within an ambient temperature range of -20

3. Store within a relative humidity range o f 0% to 90% and non-condensing environment.

4. Store within an air pressure range of 86 kPA to 106kPA.

5. DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding
environment is humid, you should put exsiccator in the package.

6. DO NOT store in an area with rapid changes in temperature. It may cause condensation and
frost.

7. If the AC motor drive is used but did not use more than three months, the temperature should
not be higher than 30 °C. Storage longer than one year is not recommended, it could result in
the degradation of the electrolytic capacitors.

8. When the AC motor drive is not used for longer time after installation on building sites or places
with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.

9. If the electrolytic capacitors do not energize for a long time, its performance will decline.
Therefore, the unused drive must be charged 3 ~4 hours every two years (*) to recover the
performance of internal electrolytic capacitor of drive.

*Note：It need to use the adjustable AC power source when the inverter power transmission
(eg.: AC autotransformer) and pressurize to the rated voltage gradually, do not do the power
transmission by using rated voltage directly.

(according to IEC 61800-3) and reduce earth leakage current.

CAUTION!

1. After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore, make sure
that main power has been switched off before cutting the RFI jumper.

2. The gap discharge may occur when the transient voltage is higher than 1,000V. Besides, electro­magnetic compatibility of the AC motor drives will be lower after cutting the RFI jumper.

3. Do NOT cut the RFI jumper when main power is connected to earth.

4. The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and motor must
be separated if high voltage test is performed and the leakage currents are
too high.

5. To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC motor drive
is installed on an ungrounded power system or a high resistance-grounded(over 30 ohms) power
system or a corner grounded TN system.

1.2.2 DC-bus Sharing: Connecting the DC-bus of the AC Motor Drives

in Parallel

1. This function is not for VFD-E-T series.

2. The AC motor drives can absorb mutual voltage that generated to DC bus when
deceleration.

3. Enhance brake function and stabilize the voltage of the DC bus.

4. The brake module can be added to enhance brake function after connecting in parallel.

5. Only the same power system and capacity can be connected in parallel.

6. It is recommended to connect 5 AC motor drives in parallel (no limit in horsepower but
these 5 drives should be the same power system and capacity).

power should be applied at the same time
(only the same power system and capacity can be connected in parallel)

Chapter 2 Installation & Wiring

Chapter 2 Installation & Wiring

After removing the front cover, check if the power and control terminals are clear. Be sure to observe
the following precautions when wiring.

General Wiring Information



Applicable Codes
All VFD-E series are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters
Laboratories (cUL) listed, and therefore comply with the requirements of the National
Electrical Code (NEC) and the Canadian Electrical Code (CEC).

Installation intended to meet the UL and cUL requirements must follow the instructions
provided in “Wiring Notes” as a minimum standard. Follow all local codes that exceed UL
and cUL requirements. Refer to the technical data label affixed to the AC motor drive and
the motor nameplate for electrical data.

The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for
each VFD-E Series part number. These fuses (or equivalent) must be used on all
installations where 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?
