2) Connect the positive and negative poles of the DC bus (48VDC) with the positive and negative board terminals in the machine wiring block respectively, and pay attention to the correct polarity. 3) After the wiring is completed, connect the DC bus lead with the DC 48VDC power supply system. In the wiring back road between the DC bus and the machine, it is necessary to install a suitable air switch to prevent fire accidents caused by short circuit. 4) Each inverter module needs to have its own DC input shunt.
