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.

Chapter 2 Product overview
2.1 Quick startup
2.1.1 Unpacking inspection
Check the following items after receiving the product.
1. Whether the packing box is damaged or dampened.
2. Whether the model identifier on the exterior surface of the packing box is consistent
with the purchased model.
3. Whether the interior surface of the packing box is abnormal, for example, in wet
condition, or whether the enclosure of the product is damaged or cracked.
4. Whether the nameplate of the product is consistent with the model identifier on the
exterior surface of the packing box.
5. Whether the accessories (including the user manual and control keypad) inside the
packing box are complete.
If any of the problems described in the check items are found, contact the local dealer or our
company.
2.1.2 Checking before applying
Confirm the following items before using the inverter.
1. Mechanical type of the load to be driven by the inverter. Check whether the inverter will
be overloaded in actual operation and whether the power level needs to be raised.
2. Whether the actual running current of the to-be-loaded motor is lower than the rated
current of the inverter.
3. Whether control precision implemented by the inverter meets the requirement of the
actual load.
4. Whether the grid voltage is consistent with the rated voltage of the inverter.
2.1.3 Environment confirmation
Check the following items before you install and use the inverter.
1. Whether the ambient temperature in the application is higher than 40°C. If yes, derate
the machine by 1% for every increased 1°C. Do not use the inverter in environments
where the temperature is higher than 50°C.
Note: If the inverter is installed in a cabinet, the ambient temperature is the air
temperature inside the cabinet.
2. Whether the ambient temperature in application is lower than –10°C. If yes, configure a
heating device.
