NOTES:
Follow the local codes and regulations when selecting field wires.
•
Power cord selection shall not be lighter than polychloroprene sheathed flexible cord (code designation
•
60245 IEC 57), and the power cord should be copper wire.
Use a shielded cable for the transmitting circuit and connect shielding layer to the ground.
•
In the case that power cables are connected in series, add maximum current to each unit and select
•
wires as follow table.

7.3 Position of Electrical Wiring Connection
WARNING
!
Tightly secure wirings to the terminal block according to the specified torque. If tightening the terminals
•
is not completed, heat generation, an electric shock or a fire will occur at the terminal connection.
Make sure that the wires are securely fixed in order not to apply an external force to the terminal
•
connection of the wirings. If fixing is not completed, heat generation or a fire will occur.
Make sure that the terminals do not touch the surface of the electrical box. If the terminals are too
•
close to the surface, it may cause the activation of ELB, heat generation and a fire at the terminal
connection, and an electrical shock.
Example for Electrical Wiring Connection
The transmission cable length between the outdoor unit and the indoor unit shall be less than 246ft(75m).

Transmission cables are not polarized
and should not be connected to strong
power terminals to prevent electrical
components from burning out. The cable
