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.
