R (L1)/S/T (L2)/PE
input terminals
It is used to connect three-phase/single-phase AC
input power supplies. R/S/T terminals are used to
connect the three-phase power supply. L1/L2
terminals are used to connect the single-phase
power supply, and PE is the protective earthing
terminal.

3 System Connection
When using the AC drive to drive an asynchronous motor, a variety of electrical
components must be installed on both input and output sides to ensure system safety
and stability. The following figure shows the system composition.

Circuit
breaker
Input side of the
drive
All models Installed between the power supply and input side of the drive.
Short circuit breaker: Cuts off the power supply when overcurrent occurs
on downstream devices to prevent accidents.
Residual current device (RCD): The drive may generate high-frequency
leakage current during running. To prevent electric shock which may
cause a fire, select a proper RCD based on actual applications.
Fuse Input side of the
drive
All models Provides protection in case of short circuit to protect downstream
semiconductors.
Electromag
netic
contactor
Input side of the
drive
All models It is used to connect to or cut off the power supply of the AC drive. Do
not use the contactor to power on or off the drive frequently (interval: at
least one hour) or use the contactor to directly start the drive.
