If you have any questions and problems about the use of our products, please contact our
agents or us.
Any improved suggestions are welcome.
Danger！
This system contains voltages that may be as high as 400 volts!
Electric shock can cause serious or fatal injury. Only qualified
personnel shall wire the drive.
Please cut off the power before wiring and inspecting. It is not
permissible to touch PCB or interior components before battery
control lamp goes off or until 5 minutes after the power has been
removed. It is necessary to use meters to confirm the charging
capacitance has discharged off. Otherwise, a risk of electric shock
may happen.
Don't contact AC power source to the output terminals U, V, W of
the ac drive.
When using the ac drive, the earthling terminal of the ac drive must
be grounded correctly and reliably according to IEC536 Class 1,
NEC and other applicable standards.
Warning！
Unauthorized change of inboard wiring and using accessories,
which sold or recommended by blame manufacturer may cause
fire, electric shock and injury.
Since body static electricity may cause serious damage to MOS
field-effect transistor and other sensitive elements, please don’t
touch the interior devices, such as PCB, IGBT module etc. before
any measure is took to prevent static electricity.
Caution！
Keep all marks and labels are clear to read. Replace the lost or worn
mark at any moment.
Please keep the user manual near the ac drive that can be reached
easily and give this manual to the users who use the product.

2.1 Exterior Size and Mounting Size (See Appendix 1)
2.2 Mounting Place Requirement and Management
Attention
· Don’t carry the ac drive by its cover. The cover cannot support the weight of the ac
drive and may drop.
· Please install the ac drive on a strong support, failing which the ac drive may fall off.
· Don’t install the ac drive in places where water pipes may leak onto it.
· Don’t allow screws, washers and other metal foreign matters to fall inside the ac
drive, otherwise there is a danger of fire or damage.
· Don’t operate the ac drive if parts are not complete, otherwise there is a danger of
fire or human injury.
· Don’t install the ac drive under direct sunshine; otherwise, it may be damaged.
· Don’t short circuit PB, + and -, otherwise there is a danger of fire or the ac drive may
be damaged.
· Cable lugs must be connected to main terminals firmly.
· Don’t apply supply voltage (AC 220V or higher) to control terminals except
terminals TA, TB, TC.
Please mount the ac drive as following application occasions and maintain appropriate
condition.
2.2.1 Installation Location
The installation location should meet the following conditions:
●Good indoor ventilation.
●Ambient temperature: -10 ℃~ 40 ℃. If the temperature is higher than 40 ℃, the ac
drive should be derating used and forced ventilation is required.
●Humidity should be lower than 95%, no condensing.
●Do not mount the ac drive on the timber or other combustible matters.
●Avoid direct sunlight.
●Mount in the location free of dust, metal powder, corrosive gas or combustible gas.
●The installation foundation should be solid and free of vibration.
●No electromagnetic interference, away from source of interference.
●Derating use must be considered when the ac drive is installed at high altitude, greater
than 1000 m. This is because the cooling effect of ac drive is deteriorated because of the
thin air. Derating 6% per 1000 m higher of the altitude.

2.2.2 The Ambient Temperature
In order to enhance operating reliability of the ac drive, be sure where the ac drive
mounted has a good ventilation; when the ac drive is used in a closed case, cooling fans
or an air-conditioning must be installed to keep the ambient temperature below 40℃.
2.2.3 Preventive Measures
Installing the ac drive, please set a shield to prevent metal debris falling into it, and
remove the shield after installing.
2.3 Installation Direction and Space
Ac drives of this series are all equipped fans for forced cooling. In order to be an
effective cooling cycle, the ac drive must be mounted in the vertical direction, up, down,
left and right away from adjacent articles or baffle(wall) maintain adequate space, as

2.4.2 Main Circuit Wiring operation
Be sure that the motor is running forward when the running direction command of ac
drive is forward. If the motor is running reverse, interchange any two-output terminals
(U, V, W) can change the rotate direction of the motor, and you can change function code
P2.25 to change phase-sequence of the motor.
Never connect input power supply cables to output terminals, or else parts of the ac drive
would be damaged. Do not connect output terminals to earth, be sure output cables not
touch to the shell or be shorted, or else the ac drive would be damaged.
Be sure Earth terminal “PE” is connected to earth. The earthling resistance of 380V-class
should be below 10Ω. Be sure the earthling not be shared with an electric welding
machines or other high-current electrical equipments. Use ground wiring as mentioned
in “Appendix 3 Main Circuit Output Cable Selection” and keep the length as short as
possible.
When two or more ac drives are used at the same time, do not loop the wires. The right
and wrong earthling connection methods are shown as Figure 2-9.
Inverter InverterRight
Inverter InverterInverter
Wrong
Inverter
Fig 2-9 Earthling Connection Method
Attention: The neutral point of motor using Y connection can’t be connected to
earth.
Since the ac drive output PWM wave, if a capacitance for improving power factor or a
lightning varistor is installed on the output side, which would case tripping or damage to
parts, be sure to remove it.
If a contactor or other on-off part is needed to be installed between the output and the
motor, be sure the on-off operation is done when the ac drive has no output, otherwise the
ac drive would be damaged.
Countermeasures to conduction interference: To inhibit conduction interference of the
output, besides installing noise filter and using shielded motor cables, leading all the
output cables to earthling metal tube is also a method. Make the distance between the
output cables and the control signal cables greater than 30 cm, the effect of conduction
interference will obviously decrease too.

Chapter 2 Installation and Wiring
http://www.acdrive-china.com

Countermeasures to RFI: The input cables, output cables and the ac drive itself would
produce RFI. Placing noise filters both at input and output sides, and shielded with metal
shell would reduce RFI. The cables between the ac drive and the motor should be as
short as possible. Measure to reduce RFI is shown as Figure 2-10.

Fig 2-10 Method to Restrain RFI
Distance between the ac drive and the motor.
The longer the distance between the ac drive and the motor, the higher the carrier
frequency would be, and the greater the high harmonic leakage current of the cables
would be. Leakage current has a negative impact to ac drives and equipments nearby, so
reduce leakage current as little as possible.
The relationship of the distance between the ac drive and the motor and carrier frequency
is shown as Table 2-7.

Fig 2-12 35R5GB/37R5PB～3500GB Arrangement of Control Circuit Terminals
In order to reduce interference and attenuation of control signal, the length of control
cables should be limited in 50m and away from power cables for more than 30cm. Avoid
control wire and power wire being parallel. Try to use STP (Shielded Twisted Pair) to
connect analog input and output signal.
