CAUTION: Appliances such as air conditioner are required at least 2-3 minutes to restart because it's required to
have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short
time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it's equipped with time-delay function before installation. Otherwise, this inverter
