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.
