range. And please operate after 5 mins.
While the inverter is working, the heatsink temperature will be higher as the consumption. To prevent

from scald, please do not touch the heatsink and do not change the fan until the temperature being safe.
 To ensure the best performance of the inverter, please use the original fan.
