Wiring procedure between indoor units
D A N G E R
•
Turn OFF the power source completely before performing the dip switch setting and electrical wiring work for receiver kit.
If not, it may cause an electric shock.
•
Perform securely the electrical wiring work. If the electrical work is not completed, heat generation at the connection, a
fire or an electric shock may occur.
•
Make sure that the electrical wires are securely fixed in order not to apply an external force to the terminal
connections of the wirings. If fixing is not completed, it may cause heat generation or a fire.
1 Lay the wiring between the indoor units after reading the re-
ceiver installation manual. The total cable length should not
exceed 500 metres.

2 Fix the connection control cable between the indoor units
at certain points with flexible flanges ensuring that it does
not run in parallel with the power supply cable inside the in-
door unit. Keep a distance of more than 30 cm between the
control cable and the power supply cable. Earth one end of
the conduit after inserting the control cable inside the metal
conduit.
N O T E
Do not run the connecting cable for receiver kit and the power source
cable (220-240V) in parallel. It may cause malfunction of receiver kit by
noise.
3 Fit the setting switches on the printed circuit boards of each
indoor unit's electrical box as shown in the figure on the right.
4 Check the number of indoor units connected using test
mode.
N O T E
The 7-segment display of the wireless remote control will show the num-
ber of indoor units connected when the operation test is carried out with
the remote control.
However, this number cannot be indicated on some models. In these
cases, check the number with the wired remote control.
