1.3 Safety guide
Only qualified electricians are allowed to operate on the inverter.
Do not carry out any wiring, inspection or component replacement 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. The table below
describes the waiting time:
Inverter model
Minimum waiting time
1PH 230V
0.4kW–2.2kW
5 minutes
3PH 230V
0.4kW–7.5kW
5 minutes
3PH 400V
0.75kW–110kW
5 minutes
Do not refit the inverter unless authorized; 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 related
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 optional brake parts (braking resistors, braking units or
feedback units) 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 erector 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.

TECDrive20-EU Series Inverter Safety precautions

The leakage current of the inverter may be above 3.5mA during operation. Ground properly
and ensure the grounding resistor is less than 10Ω. The conductivity of PE grounding
conductor is the same as that of the phase conductor.
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 properly; otherwise, the
damage to the inverter may occur.
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 cannot be used as "Emergency-stop device".
The inverter cannot be used to brake the motor suddenly. A mechanical
brake 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, set the capacitance and carry out
inspection and pilot run on the inverter before use.
Close the front cover before running; otherwise, electric shock may occur.
1.3.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to carry out
maintenance, inspection, and component replacement on the inverter.
Disconnect all the power sources applied to the inverter before terminal
wiring, and wait for at least the time designated on the inverter after
disconnecting the power sources.
Take measures to prevent screws, cables and other conductive matters
from falling into the inverter during maintenance and component
replacement.
Note:
Select proper torque to tighten screws.
Keep the inverter and its parts and components away from combustible materials during
maintenance and component replacement.

Do not carry out insulation voltage-endurance test on the inverter, or measure the control
circuits of the inverter with megameters.
1.3.4 What to do after scrapping
The heavy metals inside the inverter should be treated as industrial
effluent.
When the life cycle ends, the product should enter the recycling system.
Dispose of it separately at an appropriate collection point instead of
placing it in the normal waste stream.

parameter autotuning; and if the load cannot be removed, you can perform static
autotuning.
2. Adjust the ACC/DEC time according to the actual operation conditions of the load.
3. Perform commissioning on the machine in jogging mode and check whether the
rotating direction of the motor meets the requirement. If no, exchange the wires of any
two phases of the motor to change the running direction of the motor.

Chapter 3 Installation guidelines
The chapter describes the mechanical installation and electric installation of the inverter.
Only qualified electricians are allowed to carry out what described in this
chapter. Please operate as the instructions in Chapter 1 "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 to +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 closed 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.

Running
environment
condition
The installation site of the inverter should fulfill the following requirements.
Away from electromagnetic radiation sources.
Away from oil mist, corrosive gases and combustible gases.
Ensure foreign object like metal powder, dust, oil and water will not fall into
the inverter (do not install the inverter onto combustible object like wood).
Away from radioactive substance and combustible objects.
Away from harmful gases and liquids.
Low salt content.
No direct sunlight.
Altitude
Below 1000m.
When the altitude exceeds 3000m, consult the local TECDrive dealer or
office for details.
When the altitude exceeds 1000m, derate by 1% for every increase of
100m.
Vibration
Max. vibration acceleration: 5.8m/s2 (0.6g)
Installation
direction
The inverter should be installed on an upright position to ensure sufficient
cooling effect.
Note:
The inverters should be installed in a clean and ventilated environment according to
enclosure classification.
Cooling air must be clean, free from corrosive materials and electrically conductive dust.
3.1.2 Installation direction
The inverter may be installed in a cabinet.
The inverter needs be installed in the vertical position. Check the installation site according to
the requirements below. Refer to Appendix B "Dimension drawings" for details.
3.1.3 Installation mode
a) Wall and rail mounting for the inverters (single phase 230V/three phase 400V, ≤2.2KW and
three phase 230V, ≤0.75KW)
