Foreword
Precautions during repairs and faults:
a. When disassembling, unplugging connectors and replacing parts, make
sure to unplug or turn off the power.
b. As semiconductors (IC, etc.) are prone to being damaged by static
electricity, please use human body electrostatic discharge ground wire if it is
required to directly contact the baseplate when performing operations, or
touch the ground wire (ground wires of fridges, washing machines, etc.) with
bare hands to discharge the static electricity of the human body before
carrying out operations.
c. The circuit baseplate mixes high voltage (AC110V, AC220V) and low voltage
(12V, 5V), which may cause electric shock accident; so please do not have
direct contact without preparations.
