Installation of outdoor unit
7-3 Power supply wiring connection procedure
WARNING
• Never connect power supply wiring to the terminal block for remote
controller wiring as this could damage the entire system.
Install a ground fault circuit interrupter.
• It is obliged to install a ground fault circuit interrupter to prevent elec-
tric shock and fire accident.

CAUTION
• After finishing the electric wiring work, confirm that all the wirings are
connected securely.
〈〈Precautions when laying power wiring〉〉
• Two electric wires of different thickness cannot be connected to the
power terminal block.
(Slack in the electric wires may generate abnormal heat.)
• Use round pressure terminals with insulting sleeve for connection to
the power terminal block.
If such terminals are not available for unavoidable reasons, connect
an electric wire of the same thickness to each side as shown in the
figure.

Round pressure terminal
Connect same- It is forbidden to
thickness wiring connect two to
to both sides. one side.
Make sure to observe the following items. If they are not observed,
abnormal heat may be generated by slack in electric wires, etc.
• For wiring, use the designated power wire and connect firmly, then
secure to prevent outside pressure being exerted on the terminal
board.
• Use an appropriate screwdriver for tightening the terminal screws.
A screwdriver with a small head will strip the head and make proper
tightening impossible.
• Over-tightening the terminal screws may break them.
• See the table below for tightening torque for the terminal screws.
