Chapter 1 Safety Precautions
1.1
Safety precautions
The environment can not contain any explosive gas.
It must be wired and operated only by personnel qualified for the
specific task accordance with relevant documentation,in
particular its warning notices and safety instructions.Qualified
personnel are those who,base do n their training and
experience,are capable of identifying risks and avoiding potential
hazards when working with these products/system.
Otherwise, it may cause electronic shock.
Cut off the power supply before wiring. Otherwise, it may cause
electronic shock.
Do not touch any control port, internal boards, and their
electronic components while the electricity is turned on.
Otherwise, it may cause electronic shock.
Please make sure that the product ’ s ground wiring port is
correctly connected according to national electrical safety
standards or other related standards.
Do not touch any internal board or component until 10 minutes
after power shutdown. Please do an electricity check before
internal board maintenance. Otherwise, it may cause electronic
shock.

It is forbidden to connect AC power to the product’s output port
(U, V, W) or other control ports except for Lk, Lb, Lz. Otherwise,
it may cause damage to the VFD.
Since internal IC can be destroyed by electrostatic, please do not
touch any PCB, IC, or IGBT components without any protection.
Otherwise, it will cause an unknown fault.
Make sure that any unexpected conductor such as screws, gasket,
etc., is not left inside the VFD during maintenance. Otherwise, it
may cause damage to the VFD or even fire.
If over current happens during starting up, please check the
wiring and start up again.
Do not stop the VFD by cutting off power. Power can be cut off
after the motor stops.
Do not leave the VFD in the sunshine. Otherwise, it may cause
damage to the VFD
