1.11.1. Thermal protection
：
This machine use NTC for temperature sensing element to real time monitoring the temperature of
the critical component to protect it.
1.11.2. Overvoltage protection:
When the input voltage is below or over the specified voltage, the machine will cut off the power to
protect itself until the input voltage is available.
