Only qualified electricians are allowed to carry out what described in this chapter. Please
operate as the instructions in Safety Precautions. Ignoring these may cause physical
injury or death or damage to the devices.
Ensure the power supply of the inverter is disconnected during the operation. Wait for at
least the time designated until the POWER indicator is off after the disconnection if the
power supply is applied.
The installation and design of the inverter should be complied with the requirement of the
local laws and regulations in the installation site. If the installation infringes the
requirement, our company will exempt from any responsibility. Additionally, if users do
not comply with the suggestion, some damage beyond the assured maintenance range
may occur.
3.1 Mechanical installation
3.1.1 Installation environment
The installation environment is the safeguard for a full performance and long-term stable functions of the
inverter. Check the installation environment as followings:
Environment Conditions
Installation site Indoor
Environment
temperature
-10 ~＋40, and the temperature changing rate is less than 0.5/minute.
If the ambient temperature of the inverter is above 40, derate 1% for every
additional 1.
It is not recommended to use the inverter if the ambient temperature is above
50
In order to improve the reliability of the device, do not use the inverter if the
ambient temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal ambient
temperature below the required one if the inverter is used in a close space
such as in the control cabinet.
When the temperature is too low, if the inverter needs to restart to run after a
long stop, it is necessary to provide an external heating device to increase
the internal temperature, otherwise damage to the devices may occur.

No condensation is allowed.
The maximum relative humidity should be equal to or less than 60% in
corrosive air.
Storage

3.3 Layout protection
3.3.1 Protect the inverter and input power cable in short-circuit situations
Protect the inverter and input power cable in short circuit situations and against thermal overload.
Arrange the protection according to the following guidelines.
Figure 3-7 Fuse configuration
Note: Select the circuit breaker as the manual indicates. The circuit breaker will protect the input power cable
from damage in short-circuit situations. It will protect the surrounding devices when the internal of the inverter is
short circuited.
3.3.2 Protecting the motor and motor cables
The inverter protects the motor and motor cable in a short-circuit situation when the motor cable is dimensioned
according to the rated current of the inverter. No additional protection devices are needed.
If the inverter is connected to multiple motors, a separate thermal overload switch
or a circuit breaker must be used for protecting each cable and motor. These
devices also may require a separate circuit breaker to cut off the short-circuit
current.
3.3.3 Implementing a bypass connection
It is necessary to set power frequency and variable frequency conversion circuits for the assurance of
continuous normal work of the inverter if faults occur in some significant situations.
In some special situations, for example, if it is only used in soft start, the inverter can be conversed into power
frequency running after starting and some corresponding bypass should be added.
Never connect the supply power to the inverter output terminals U, V and W.
Power line voltage applied to the output can result in permanent damage to
the inverter.
If frequent shifting is required, employ mechanically connected switches or contactors to ensure that the motor
terminals are not connected to the AC power line and inverter output terminals simultaneously.

In the running state, there are 22 parameters can be selected to be displayed or not. They are: running
frequency, set frequency, bus voltage, output voltage, output torque, PID reference, PID feedback, input
terminals state, output terminals state, and the current stage of multi-step speeds, pulse counting value, AI1,
AI2, percentage of motor overload, percentage of inverter overload, linear speed. P07.05 and P07.06 can
select the parameter to be displayed or not by bit and 》/SHIFT can shift the parameters from left to right,
QUICK/JOG (P07.02=2) can shift the parameters from right to left.
4.1.3 Displayed state of fault
If the inverter detects the fault signal, it will enter into the fault pre-alarm displaying state. The keypad will
display the fault code by flicking. The TRIP LED on the keypad is on, and the fault reset can be operated by the
STOP/RST on the keypad, control terminals or communication commands.
4.1.4 Displayed state of function codes editing
In the state of stopping, running or fault, press PRG/ESC to enter into the editing state (if there is a password,
see P07.00 ).The editing state is displayed on two classes of menu, and the order is: function code
group/function code numberfunction code parameter, press DATA/ENT into the displayed state of function
parameter. On this state, press DATA/ENT to save the parameters or press PRG/ESC to escape.

4.2 Keypad operation
Operate the inverter via operation panel. See the detailed structure description of function codes in the brief
diagram of function codes.
4.2.1 How to modify the function codes of the inverter
The inverter has three levels menu, which are:
1. Group number of function code (first-level menu)
2. Tab of function code (second-level menu)
3. Set value of function code (third-level menu)
Remarks: Press both the PRG/ESC and the DATA/ENT can return to the second-level menu from the
third-level menu. The difference is: pressing DATA/ENT will save the set parameters into the control panel, and
then return to the second-level menu with shifting to the next function code automatically; while pressing
PRG/ESC will directly return to the second-level menu without saving the parameters, and keep staying at the
current function code.
Under the third-level menu, if the parameter has no flickering bit, it means the function code cannot be modified.
The possible reasons could be:
1) This function code is not modifiable parameter, such as actual detected parameter, operation records and so on;
