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 inverter.
When using the inverter, the earthling terminal of the inverter 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 taken to prevent static electricity.
Caution!
Keep all marks and labels clear to read. Replace the lost or worn
mark at any moment.
Please keep the user manual near the inverter that can be reached
easily and give this manual to the users who use the product.
All rights reserved. The contents in this document are subject to change without notice.
If you have any questions and problems about the use of our products, please contact our
agents or us.

2.1 Exterior Size and Mounting Size (See Appendix 1)
2.2 Mounting Place Requirement and Management
Attention
· Don’t carry the inverter by its cover. The cover cannot support the weight of the
inverter and may drop.
· Please install the inverter on a strong support, failing which the inverter may fall off.
· Don’t install the inverter in places where water pipes may leak onto it.
· Don’t allow screws, washers and other metal foreign matters to fall inside the
inverter, otherwise there is a danger of fire or damage.
· Don’t operate the inverter if parts are not complete, otherwise there is a danger of
fire or human injury.
· Don’t install the inverter under direct sunshine; otherwise, it may be damaged.
· Don’t short circuit PB, + and -, otherwise there is a danger of fire or the inverter 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 inverter 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
inverter should be derating used and forced ventilation is required.
 Humidity should be lower than 95%, no condensing.
Do not mount the inverter 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 inverter is installed at high altitude,
greater than 1000 m. This is because the cooling effect of inverter is deteriorated
because of the thin air. Derating 6% per 1000 m higher of the altitude.

Chapter 2 Installation and Wiring

2.2.2 The Ambient Temperature
In order to enhance operating reliability of the inverter, be sure where the inverter
mounted has a good ventilation; when the inverter 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 inverter, please set a shield to prevent metal debris falling into it, and
remove the shield after installing.
Please remove the protection membrane when the ambient temperature is over 40℃or
the internal temperature is too high due to other reasons. Please pay attention to avoid
small parts falling into the inverter.
2.3 Installation Direction and Space
Inverters of this series are all equipped fans for forced cooling. In order to be an effective
cooling cycle, the inverter must be mounted in the vertical direction, up, down, left and
right away from adjacent articles or baffle (wall) maintain adequate space, as Figure 2-1

2.4.2 Main Circuit Wiring Operation
When the motor is running, please make sure if it is in positive rotation while the motor
receives positive rotation command. If the motor is in reverse rotation, the rotation
direction of the motor can be changed by exchanging any two wires of output terminals
(U, V, and W) of the inverter. The rotation direction can also be changed by modifying
the function code P2.33 to change the phase sequence of the motor.
Do not mistakenly connect the input power cable to the output terminal; otherwise the
components in the inverter will be damaged. Output terminals are prohibited to be
grounded. The lines should not be collided with the enclosure, or short connected;
otherwise the inverter will be damaged. Be sure Earth terminal “PE” is connected to
earth. The earthing resistance of 380V-class should be below 10Ω. Be sure the earthing
not be shared with 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 inverters 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 Earthing Connection Method
Attention: The neutral point of motor using Y connection can’t be connected to
earth.
Since the inverter output PWM wave, if a capacitance for improving power factor or a
lightning varistor is installed on the output side, which would cause 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 inverter has no output, otherwise the
inverter 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 earthing metal tube is also a method. Make the distance between the

Chapter 2 Installation and Wiring
16
output cables and the control signal cables greater than 30 cm, the effect of conduction
interference will obviously decrease too.
Countermeasures to RFI: The input cables, output cables and the inverter 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 inverter 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 inverter and the motor.
The longer the distance between the inverter 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 inverters and equipments nearby, so
reduce leakage current as little as possible.
The relationship of the distance between the inverter and the motor and carrier frequency
is shown as Table 2-7.

Fig. 2-13 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.
