摘要： An installation system of inverter wires and motor wires includes a plurality of positioning modules, a driving device and a control unit. Each positioning module includes a positioning unit and a pressure sensor. The positioning unit corresponds to a fixing hole of a motor wire of a motor. The pressure sensor is arranged on the positioning unit and configured to sense a pressure applied from an inverter wire of an inverter. The driving device is configured to drive the positioning unit to penetrate through or away from the fixing hole of the motor wire according to whether a pressure applied from the inverter wire is greater than a predetermined value, such that a fixing hole of the inverter wire is able to be aligned with the fixing hole of the motor wire and the fixing hole of the junction block.
