9. Troubleshooting Safety Electricity power is still kept in capacitors even the power supply is shut off. Do not forget to discharge the electricity power in capacitor. Electrolytic Capacitors (HIGH VOLTAGE! CAUTION!) For other models, please connect discharge resistance (approx.100Ω 40W) or soldering iron (plug) between +, terminals of the electrolytic capacitor on the contrary side of the outdoor PCB. Note: The picture above is only for reference. The plug of your side may be different.
