Chapter 2 Installation
2-1 Installation environment
Locations free of water droplets, vapors, dust and oily dust.
Non-corrosive, flammable gas and liquid.
No floating dust metal particles.
Strong and vibration-free place.
Locations without electromagnetic noise interference.
The environment temperature is -10 °C ∼40 °C. If the environment temperature
exceeds 40 °C, please place it in a well ventilated place and derate the inverter.
2-2 Installation method and space
The inverter should be installed on a structure that does not burn, such as metal,
otherwise a fire accident may occur.
The inverter should be installed vertically and securely with screws. Do not flip,
tilt or install horizontally. When the inverter runs, heat is generated. To ensure the
passage of the cooling air, a certain space is left during installation (as shown in the
figure).
When installing the inverter in the control cabinet, consider ventilation and heat
dissipation to ensure that the ambient temperature of the inverter does not exceed
the specified value. Do not install the inverter in a closed box with poor ventilation.
When installing multiple inverters in the same control cabinet, it is recommended
to install them side by side in order to reduce the thermal impact between each
other. If it is necessary to install up and down, a partition plate must be provided to
reduce the influence of heat generated in the lower part on the upper part (as shown
in the figure).
Do not allow foreign matter such as various fibers, paper sheets, chips (chips) or
metal fragments to enter the inverter.

Chapter 3 Wiring
In order to ensure the safety of operators and inverters, it is necessary to be operated by
qualified professional electricians. The following are special considerations when wiring：
Make sure the input power is off before wiring.
The ground terminal of the inverter must be reliably grounded.
Verify that the rated voltage of the inverter matches the AC power supply
voltage.
The power cable must be connected to the R, S, and T terminals of the
inverter. The motor cable should be connected to the U, V, and W terminals.
Do not connect the fault. Otherwise, the inverter will be damaged internally.
Confirm that the terminals and wires are reliably connected, and the screws
of the main circuit terminals are secured.
Do not touch the main circuit terminals, otherwise there is danger of
electric shock.

When wiring, please follow the electrical regulations to ensure the safety.
3-3-1 Power input terminal R，S，T
◆A circuit breaker is required between the three-phase AC input power supply and the
main circuit terminals (R, S, T). It is better to connect a magnetic contactor (MC) in series to
cut off the power supply when the inverter protection function is activated (the R-C surge
absorber is required at both ends of the electromagnetic contactor).
◆If the inverter is equipped with an earth leakage circuit breaker as a leakage fault
protection, in order to prevent the leakage circuit breaker from malfunctioning, please select
a sensitivity current of 200 mA or more and an operation time of 0.1 second or longer.
◆In order to prevent the high voltage and high current input into the power supply
circuit and damage the rectifier part, it is necessary to connect the AC reactor on the input
side, and also improve the power factor of the input side.
◆Do not use the main circuit power ON/OFF method to control the operation and stop
of the inverter. The drive's operation and stop should be controlled using the RUN and STOP
keys on the keypad panel or the control loop terminals. If the main power ON/OFF method
must be used to control the operation of the inverter, it can only be performed once per hour.
◆To reduce the interference of the inverter to surrounding equipment, the noise filter
can be connected to the input side.
◆Do not connect the three-phase power supply to the single-phase power supply.

Chapter 3 Wiring
11
3-3-2 Connection of inverter output terminals U, V, W
◆The inverter output terminals are connected to the 3-phase motor in the correct
phase sequence. If the motor rotates in the wrong direction, the wiring of any two phases of
U, V, W can be exchanged.
◆The output side of the inverter cannot be connected to the capacitor and the surge
absorber.
◆When the wiring between the inverter and the motor exceeds 50 meters, the
distributed capacitance between the lines will generate a large leakage current, which may
cause the inverter to over-current trip. At the same time, in order to avoid damage to the
motor insulation, the output reactor must be compensated. .
◆If the installation location of the inverter is quite sensitive to interference, please
install an output noise filter to reduce the carrier frequency of the inverter and reduce
interference.
3-3-3 Braking resistor and brake unit connection
◆When the load inertia is large and it is necessary to stop frequently or stop for a short
time, when the braking capacity of the inverter is insufficient or to increase the braking torque,
etc., the braking resistor or the braking unit may be selected as needed.
◆The main circuit B1, B2 terminal is connected to the braking resistor (there is B1, B2
terminal indicates that the inverter has built-in braking unit).
◆When the inverter has no built-in braking unit, the main circuit (+) and (-) terminals
are connected to the external braking unit.
◆Do not connect the main circuit (+) and (-) terminals to the braking resistor.
3-3-4 Inverter Grounding Terminal PE
◆For safety and noise reduction, the ground terminal PE of the inverter must be well
grounded.
◆Use the specified standard grounding wire and be as short and thick as possible
(grounding impedance 10Ω or less).
◆The grounding wire of the inverter must not be grounded together with large current
loads such as electric welders and high-power motors, but must be grounded separately.
◆The power supply line generally adopts 5 core wires, of which 3 are fire wires, 1
neutral wire, and 1 ground wire. It is strictly forbidden to use the neutral wire as ground wire.
◆When multiple inverters are installed together, all inverters must be directly

4-2 Function code modification, view instructions
Function code modification instructions
The operation panel of the inverter adopts a three-level menu structure for parameter
setting and other operations. The three levels of menu are: function parameter group (first
level menu) → function code (second level menu) → function code setting value (third level
menu)。
The operation process is shown in Figure 4-2.

menu operation flow
Chart
Note: When operating in a three-level menu, press the PRG or ENTER key to return to the
secondary menu. The difference between the two is: press the ENTER key to save the set
parameters and return to the second level menu, and automatically transfer to the next function
code; press the PRG key to return directly to the second level menu, do not store the parameters,
and return to the current function code .
Example: An example of changing the function code P3-02 from 10.00 Hz to 15.00 Hz. (black
mark indicates flashing bit)
In the third level menu, if there is no flashing bit in the parameter, it
means that the function code cannot be modified. The possible
reasons are as follows:
1) The function code is an unmodifiable parameter. Such as the
actual detection parameters, operating record parameters.
2) The function code cannot be modified in the running state, and
can be modified after it needs to be stopped.

How to view status parameters
In the stop or running state, the shift key can be used to switch between displaying
various status parameters. The function code P7-03 (operation parameter 1), P7-04
(operation parameter 2), P7-05 (stop parameter) is selected according to the binary bit to
display whether the parameter is displayed.
For example, in the stop state, P7-05 (stop parameter) is set to 33,
P7-05=0000 0000 0011 0011B=33 The four status parameters of Bit00/Bit01/Bit04/Bit05
are selected: set frequency, bus voltage, AI1 voltage, AI2 voltage, and the key sequence
switches to display the selected parameter.
In the running state, P7-03 (operation parameter 1) is set to 7F,
P7-05=0000 0000 0111 1111B=7F The 7 status parameters of
Bit00/Bit01/Bit03/Bit03/Bit04/Bit05/Bit06 are selected: running frequency, set frequency, bus
voltage, output voltage, output current, output Power, output torque, key sequence switching
to display the selected parameters,
After the inverter is powered off and then powered on, the displayed parameters are
defaulted to the parameters selected before the inverter is powered down.

User password setting
The inverter provides the user password protection function. When PP-00 is set to non-zero, it
is the user password. Exiting the function code editing status password protection takes effect.
Press PRG again, “-----” will be displayed. Enter the user password correctly to enter the
normal menu, otherwise you will not be able to enter, so you must remember the password
after setting the user password.
To cancel the password protection function, only enter with a password and set PP-00 to 0.
