1.4 Safety guidelines
Only trained and qualified electricians can operate the VFD.
Do not perform any wiring, inspection, or component changing when power is
applied. Ensure all input power supplies are disconnected before wiring or
checking, and always wait at least the time designated on the VFD or until the
DC bus voltage is less than 36V. The following table lists the waiting time.

Do not refit the VFD unless authorized; otherwise, fire, electric shock or other
injuries may result.
The heat sink base may become hot during running. Do not touch it; otherwise,
burns may result.
The electronic components inside the VFD are electrostatic sensitive. Take
measurements to avoid electrostatic discharge during related operation.
1.4.1 Delivery and installation
Install the VFD on fire-retardant material and keep the VFD away from
combustible materials.
Connect the optional braking parts (braking resistors, braking units or feedback
units) according to the wiring diagram.
Do not run a damaged or incomplete VFD.
Do not touch the VFD with wet items or body parts; otherwise, electric shock
may result.
Note:
Select appropriate tools for delivery and installation to ensure proper VFD running and prevent
accidents. To ensure physical safety, take mechanical protective measures such as wearing
safety shoes and working uniforms.
Prevent the VFD from physical shock or vibration during delivery and installation.
Do not carry the VFD only by its front cover as the cover may fall off.
Install the VFD far away from children and other public places.
Use the VFD in proper environments. (For details, see the installation environment.)
Prevent screws, cables and other conductive parts from falling into the VFD.
