Check for Power Supply Short Circuit
After completing the cabinet wiring, please use a multimeter to check if there is any short circuit at the
AC input power supply (L / N / PE) and DC output terminal (VCC / GND). If there is a short circuit,
please carefully investigate the wirings. Make sure all wirings are normal, and only then connect power
to operate the unit.
