Chapter 1 Inverter Installation

Please confirm carefully when unpacking: Whether there is any damage during transportation; whether the

model and specifications on the nameplate of this machine are consistent with the ordering requirements. If

you find that the model does not match or components are missing, please contact the manufacturer or

supplier. For inverters that have been stored for more than one year, the voltage should be slowly boosted

by a regulator during power-on, otherwise there is a risk of electric shock and explosion. When handling,

please focus force on the bottom of the body.

1. Do not lift the operation panel or cover when handling, otherwise there is a

danger of inverter falling and being damaged.

2. When installing, consider the bearing capacity of platform, otherwise there is a

danger of inverter falling and being damaged.

3. It is strictly forbidden to install the inverter in places where water droplets may

splash, otherwise there is danger of damage.

4. It is strictly forbidden to cause metal powder, oil, water, etc. to enter the inverter,

otherwise there is danger of damage and explosion.

5. When the inverter is damaged or parts are incomplete, please do not install and

operate, otherwise there is danger of damage to the inverter.

6. Do not install in a place exposed to direct sunlight, otherwise there is a danger

of overheating and accidents.

1. It must be installed on incombustible materials such as metal, otherwise there is a

danger of fire.

2. There must be no combustibles nearby, otherwise there is a danger of fire.

3. Do not install in an environment containing explosive gases, otherwise there is a

danger of explosion.

Installation site of the inverter must meet the following conditions:

a) A clean site without oil mist, dust, or a fully enclosed cabinet where floats cannot intrude.

b) A site without radioactive materials.

c) A site without hazardous gas, liquid, or with less salinity.

d) Asite with low vibration, the fasteners must have anti-vibration parts, such as spring washers, and the

screws of the inverter must be tightened.

e) When installing the inverter in a closed cabinet, install a cooling fan or cool the air conditioner to keep

the temperature below 40 °C.

f) Vertically install in a well ventilated area.

Chapter 2 Inverter Wiring

◎Before wiring, please confirm whether the input power is completely disconnected.

Otherwise there is danger of electric shock.

◎Please request professional electrical engineers to perform wiring.

Otherwise there is danger of electric shock.

◎Be sure to ground the ground terminal PE reliably.

Otherwise there is danger of electric shock.

◎Do not touch the terminal directly with your hand. Do not touch the output line of the inverter

with its cover.

Otherwise there is danger of electric shock.

◎Do not connect power supply to the output terminals U/T1, V/T2, W/T3.

Otherwise there is a danger of damage to the inverter.

◎Do not make the terminals ○＋1/○＋2 and○－short connected.

Otherwise there is a danger of explosion.

◎Check that the voltage of AC main circuit power supply is consistent with the rated voltage of

the inverter.

Otherwise there is a danger of fire and personal injury.

◎Connect the braking resistor correctly according to wiring diagram.

Otherwise there is a danger of fire.

◎The main circuit terminal must be securely connected to the wire or wire crimp terminal.

Otherwise there is a danger of damage to the inverter.

Inverter and Peripheral Device Connection

Figure 2.1 Inverter and Peripheral Device Connection Diagram

Note: The diagram is drawn taking a three-phase power input as an example.

1、Inverter input side

DC reactor: Improve the power factor of power supply at the input side and reduce the high harmonic current; a

built-in DC reactor of the ≥37kW inverters.

AC reactor: Improve the power factor of power supply at the input side and reduce the high harmonic current.

Inverter-specific filter: suppress high-frequency noise interference from the inverter.

2、Inverter output side

Inverter-specific filter: suppress high-frequency noise interference from the inverter.

AC reactor: If the wiring between the inverter and the motor is too long, the high-order harmonic current leakage

will increase due to the influence of the distributed capacitance of the wire, which may cause the inverter to

activate output over-current protection. Therefore, the wiring length between the inverter and the motor should

not exceed 100m. If the wiring length exceeds 100m, the reactor and output filter should be optionally

configured.

Do not connect a capacitor or a surge filter to the output side of the inverter. The inverter outputs high order

harmonics, so connecting the capacitor or surge filter to the output side may overheat and damage the inverter.

Figure 2.2 Inverter output side error connection

3、Braking resistor

Inverters of ≤30kW come with a built-in braking unit as a standard, and an external braking resistor; Inverters

of >30kW feature an optional external braking unit. An external braking resistor can be connected. It is

necessary to fully consider heat dissipation conditions of the braking resistor, and ensure that it is well ventilated.

Wiring length of the braking resistor must not exceed 5m.

4、Grounding

The grounding terminal is preferably a dedicated grounding electrode with a impedance of 10 Ω or less. Do not

share with welding machines or other power equipment. Use the grounding wire specified in the electrical

equipment technical standard, and keep it as short as possible. If the grounding wire is too long, leakage

current of the inverter will make the potential of grounding terminal unstable. It is recommended to use a special

yellow-green grounding wire. See the table below for the grounding wire specifications. When multiple inverters

are grounded, it is recommended to avoid forming loops so as to avoid circuits formed by grounding wires.
