9. ELECTRICAL WIRING

WARNING
Before starting work, check that power is not being supplied
to the indoor unit and outdoor unit.
Match the terminal board numbers and connection cord colors
with those of the outdoor unit or branch box. Erroneous wiring
may cause burning of the electric parts.
Connect the connection cords firmly to the terminal board.
Imperfect installation may cause a fire.
Always fasten the outside covering of the connection cord
with the cable clip. (If the insulator is chafed, electric leakage
may occur.)
Always connect the ground wire.
(1) Use ring terminals with insulating sleeves as shown in the
figure below to connect to the terminal block.
(2) Securely clamp the ring terminals to the wires using an
appropriate tool so that the wires do not come loose.
(3) Use the specified wires, connect them securely, and fasten
them so that there is no stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal screws.
Do not use a screwdriver that is too small, otherwise, the
screw heads may be damaged and prevent the screws
from being properly tightened.
(5) Do not tighten the terminal screws too much, otherwise,
the screws may break.
(6) See the table 1 for the terminal screw tightening torques.
