4.2.2 Breaker
The breaker must be used between the power supply and input terminal of elevator integrated
drive controller. the capacity of breaker should be 1.5～2 times of the rated current of AS 380
series elevator integrated drive controller. The time behavior of overheating protection of elevator
integrated drive controller should be taken into full consideration for that of the breaker.
4.2.3 AC reactor at the input side
AC reactor at the input side can be used as option to improve the power factor of input power
supply and reduce ultra-harmonics current.
4.2.4 Interference filter at the input side
Specialized interference filter at the input side can be used as option to restrain power supply from
high frequency noise interference of elevator integrated drive controller.
4.2.5 Main circuit output contactor
This contactor is used for controlling the current flow of tractor. The contractor engages every
time before the elevator start up and release when the elevator stops. It is must-have safety device
installed between the drive device and tractor motor.
4.2.6 Interference filters at the output side.
Specialized interference filter at the input side can be used to restrain the power supply from high
frequency noise interference of elevator integrated drive controller.
4.2.7 AC reactor at output side
The AC reactor at the output side is used as option to restrain the radio-frequency interference of
elevator integrated drive controller.
When the wiring length between elevator integrated drive controller and motor is too long
（>20m）, the AC reactor at output side can prevent the overflow of elevator integrated controller
caused by wire distributed capacitance.
4.2.8 DC reactor
DC reactor can be used as option for the improvement of power factor.
