Peripheral Device Connection - Veikong VFD200A Series Operation Manual

3-1 Peripheral device connection

Three-phase AC
power supply
Moulded case circuit
breaker (MCCB) or earth
leakage circuit breaker
(ELCB)
Electromagnetic
contactor
AC input
reactor
Noise filter on
input side
Reduce the
electromagnetic
interference on
the input side
Reliably ground the motor and the
AC drive to prevent electric
shock.
Chapter 3 Wiring
Use within the allowable power
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.
