1. Safety Caution
WARNING
Be sure to turn off all power supplies or disconnect all wires to avoid electric shock.
While checking indoor/outdoor PCB, please equip oneself with antistatic gloves or wrist
strap to avoid damage to the board.
WARNING
Electricity remains in capacitors even when the power supply is off.
Ensure the capacitors are fully discharged before troubleshooting.
Test the voltage between P and N on back of the main PCB with multimeter. If the voltage is lower than 36V, the
capacitors are fully discharged.
