  • Page 24 2-5 Wiring If the ferrite cores cover the shield coating, they fail to work effectively, causing the Inverter to mal- function. Be sure to fix the ferrite cores or take other appropriate measures so that they do not over- lap the shield coating. The shield wire connected to the terminal could become disconnected due to the weight of the ferrite cores.
