10. 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 MSV1-09HRFN1-MT0W and MSV1-12HRFN1- MT0W models, there is a discharge resistance fixed on outdoor

PCB board already. Just wait for 10 minutes and the electricity power in capacitor will be discharged over automatically.
