4.3 The test of setting up an electric circuit
After the cabinet connection is completed, please use a multimeter to measure whether
there is short circuit at the AC input (L/N/PE) and DC output (VCC/GND) of the power
supply. If a short circuit is found, please check the circuit carefully. After ensuring the
cable is normal, switch on the power to electrify the cabinets to work.
