Instruction Manual for AS380 Series Elevator Integrated Drive Controller
Appendix A EMC Installation Guide
filter and supply line AC reactor shall be installed. In order to meet the EMC directive, the
interiors of control cabinet shall also be arranged in accordance with EMC requirements.
In the drive system constituted by elevator integrated drive controller and motor, the elevator
integrated drive controller, brake units and contactors are all heavy noise source which may affect
the normal operation of such noise sensitive peripherals as automated assembly, encoder and
sensor. On the basis of electric characteristics of peripherals, they will be installed at different
EMC zones in order to spatially isolate the noise sources and noise receivers. This is an effective
measure for eliminating interferences.
See Figure A8.1 for EMC installation zoning for elevator integrated drive controller.
Fig A8.1 EMC Zone for installation of elevator integrated drive controller
Description of above shown EMC zoning for installation:
I zone: Control supply transformer, control device and sensor
II zone: Control signal cable interface requiring certain anti-interference capacity
III zone: Main noise sources including input reactor, elevator integrated drive controller, brake
unit, contactor and the like
IV zone: Output noise filter and its wiring
V zone: Power supply (includes wiring of radio noise filter)
VI zone: Motor and its cable
These zones shall be separated by minimum 20cm in order to realize electromagnetic decoupling;
for better decoupling effect, ground separator is preferred among the zones. The cables shall be
laid and arranged by zone; if necessary, filters shall be installed at interfacing point between zones;
all the bus cables led out from cabinet (e.g. RS485) and signal cable must be shielded.
A9 Precautions for Electric Installation
