supply specification of the AC drive.
Select a proper breaker to resist
large in-rush current that flows
into the AC drive at power-on.
To guarantee safety, use an
electromagnetic contactor. Do not
use it to start or stop the AC drive
because such operation reduces
the service life of the AC drive.
Suppress the high order harmonic
to improve the power factor.
Reduce the electromagnetic
interference on the input side.
