5.3 Measure the power supply for short circuit
After wiring the cabinets, 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 line is normal, electrify the cabinet to work.
