Electrical Wiring
Make sure the power supply is OFF before carrying out work on the
wiring or inspections involving disassembly. If such work is carried out
with the power on, there is a danger that equipment may malfunction or
electric shock may occur, leading to injury or other accidents.
CAUTION
Make sure that wiring work requiring a special license is carried out only
by qualified personnel. If carried out by unqualified personnel,
overheating or short circuits leading to injury, fires, damage or other
accidents may occur.
