SAFETY CAUTION
Test the voltage between P and N on the back of the main PCB with a multimeter. If the voltage is lower than 36V, the capacitors are fully dis-
charged.
Fig. 52 —Testing
Be sure to turn off all the power supplies or disconnect all
wires to avoid electric shock.
While checking the indoor or outdoor PCB, equip yourself
with anti-static gloves or a wrist strap to avoid damage to the
board.
WARNING
Electricity remains in the capacitors even when the power
supply is off.
Ensure the capacitors are fully discharges before
troubleshooting.
