1.3 Safety guide
Only qualified electricians are allowed to operate on the VFD.
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 VFD or until the DC bus voltage is less than 36V.
The table below describes the waiting time:
VFD 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 VFD 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 VFD are electrostatic.
Take measurements to avoid electrostatic discharge during related
operation.
1.3.1 Delivery and installation
Please install the VFD on fire-retardant material and keep the VFD away
from combustible materials.
Connect the optional brake parts (brake resistors, brake units or
feedback units) according to the wiring diagram.
Do not operate on the VFD if there is any damage or components loss to
the VFD.
Do not touch the VFD 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
VFD 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 VFD by its cover. The cover may fall off.
Install away from children and other public places.
The VFD cannot meet the requirements of low voltage protection in IEC61800-5-1 if the
altitude of installation site is above 2000m.
The leakage current of the VFD 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 (with the same cross sectional area).
