1.3 Safety guidelines
Only qualified electricians are allowed to operate on the inverter.
Do not carry out any wiring and inspection or changing components when the power
supply is applied. Ensure all input power supply is disconnected before wiring and
checking and always wait for at least the time designated on the inverter or until the DC
bus voltage is less than 36V. Below is the table of the waiting time:
Inverter module Minimum waiting time
1PH 220V 0.4kW-2.2 kW 5 minutes
3PH 220V 0.4kW-7.5 kW 5 minutes
3PH 380V 0.75kW-7.5 kW 5 minutes
Do not refit the inverter unauthorized; otherwise fire, electric shock or other injury may
occur.
The base of the radiator may become hot during running. Do not touch to avoid hurt.
The electrical parts and components inside the inverter are electrostatic. Take
measurements to avoid electrostatic discharge during relevant operation.
1.3.1 Delivery and installation
Please install the inverter on fire-retardant material and keep the inverter away from
combustible materials.
Connect the braking resistors according to the wiring diagram.
Do not operate on the inverter if there is any damage or components loss to the inverter.
Do not touch the inverter with wet items or body, otherwise electric shock may occur.
Note:
Select appropriate moving and installing tools to ensure a safe and normal running of the inverter
and avoid physical injury or death. For physical safety, the installer should take some mechanical
protective measurements, such as wearing exposure shoes and working uniforms.
Ensure to avoid physical shock or vibration during delivery and installation.
Do not carry the inverter by its cover. The cover may fall off.
Install away from children and other public places.
The inverter cannot meet the requirements of low voltage protection in IEC61800-5-1 if the sea level
of installation site is above 2000m.
The leakage current of the inverter may be above 3.5mA during operation. Ground with proper
techniques and ensure the grounding resistor is less than 10. The conductivity of PE grounding
conductor is the same as that of the phase conductor (with the same cross sectional area).
R, S and T are the input terminals of the power supply, while U, V and W are the motor terminals.
Please connect the input power cables and motor cables with proper techniques; otherwise the
damage to the inverter may occur.

6 - 140 Safety precautions
1.3.2 Commissioning and running
Disconnect all power supplies applied to the inverter before the terminal wiring and wait
for at least the designated time after disconnecting the power supply.
High voltage is present inside the inverter during running. Do not carry out any operation
except for the keypad setting.
The inverter may start up by itself when P01.21=1. Do not get close to the inverter and motor.
The inverter can not be used as “Emergency-stop device”.
The inverter can not be used to break the motor suddenly. A mechanical braking device
should be provided.
Note:
Do not switch on or off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check and fix the capacitance and try to run it
again before utilization (see Maintenance and Hardware Fault Diagnose).
Cover the front board before running, otherwise electric shock may occur.
1.3.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance, inspection, and
components replacement of the inverter.
Disconnect all power supplies to the inverter before the terminal wiring. Wait for at least
the time designated on the inverter after disconnection.
Take measures to avoid screws, cables and other conductive materials to fall into the
inverter during maintenance and component replacement.
Note:
Please select proper torque to tighten screws.
Keep the inverter, parts and components away from combustible materials during maintenance and
component replacement.
Do not carry out any isolation and pressure test on the inverter and do not measure the control
circuit of the inverter by megameter.
1.3.4 What to do after scrapping
There are heavy metals in the inverter. Deal with it as industrial effluent.

3 Installation Guidelines
The chapter describes the mechanical installation and electric installation.
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 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 follows:
Environment Conditions
Installation site Indoor
Environment
temperature
-10°C~+50°C, and the temperature changing rate is less than 0.5°C/minute.
If the ambient temperature of the inverter is above 40°C, derate 1% for every
additional 1°C.
It is not recommended to use the inverter if the ambient temperature is above 50°C.
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.
Humidity RH90%
No condensation is allowed.
Storage
temperature -40°C~+70°C, and the temperature changing rate is less than 1°C/minute.

chose: 0~10V/0~20mA; AI3:-10V~+10V.
2. Input impedance: for voltage input,
20k; for current input, 500.
3.Voltage or current input can be
set by dip switch
4. Resolution: the minimum AI2/AI3 is
10mV/20mV when 10V corresponds to 50Hz.
AI3
GND Analog reference
ground Analog reference ground
AO1
Analog output
1. Output range: 0~10V or 0~20mA
2. The voltage or the current output
selection depends on the dip switch
3. Deviation ±1%, 25°C when full range

20 - 140 Installation Guidelines
3.2.6 Input/Output signal connection figure
Please use U-shaped contact tag to set NPN mode or PNP mode and the internal or external power supply.
The default setting is NPN internal mode.
Figure 3-11 U-shaped contact tag
If the signal is from NPN transistor, please set the U-shaped contact tag between +24V and PW as below
according to the used power supply.
Figure 3-12 NPN modes
If the signal is from PNP transistor, please set the U-shaped contact tag as below according to the used
power supply.
