Part Mounting Location Function Description
Safety
contactor
Between MCCB and the
controller input side
Apply/Cut off the power supply of the controller.
The close/open of the contactor is controlled by the
external safety circuit.
AC input
reactor
Controller input side
Improve the power factor of the input side.
Eliminate the higher harmonics on the input side to
provide effective protection on the rectier bridge.
Eliminate the input current unbalance due to
unbalance between the power phases.
AC
output
reactor
Between the controller
output side and the motor,
close to the controller
If the distance between the controller and the
motor is greater than 100 m, install an AC output
reactor.
3.4.2 Selection of Peripheral Electrical Devices
Proper cable specification and cabling greatly improves anti-interference capability and
safety of the system, facilitating installation and commissioning and enhancing system
running stability.
The following table describes the specications of peripheral electrical devices for selection.
