CAUTION
•
Do not bind up the power cable together with the
transmission cable or remote controller cable. It will cause
erroneous operation.
•
When performing wiring work, be careful not to damage
the cable or injure yourself. Also, connect the connectors
securely. Loose connectors will cause trouble, heating,
fire, or electric shock.
•
Install the indoor and outdoor units, power cable, signal
cable and remote control cable 1 m away from television
and radio to avoid distorted images and noise.
•
Perform wiring so that water does not enter this unit along
the external wiring. Always install a trap to the wiring
or take other countermeasures. Otherwise it will cause
trouble or electric shock or fire.
•
Confirm the name of each unit and name of each terminal
board of the unit and connect the wiring in accordance
with the directions given in the manual so that there is no
incorrect wiring. Incorrect wiring will damage the electric
parts and cause smoke and fire.
•
When installing the connection cables near a source of
electromagnetic waves, use shielded cable.
Otherwise, a breakdown or malfunction could result.
•
The terminal screws and ground screws have different
shapes. Be sure to install the screws in the correct
locations. If the screws are installed in the wrong
locations, the circuit board could be damaged.

Connect receiver unit cable B to CN13 on the PCB.
Route the receiver unit cable using the same method for
the remote controller cables as described in the installation
manual of the indoor unit.
Fasten the receiver unit medium binder (included with the standard
parts), which is used for clamping cables, on the insulating tube.
Fasten the EMI filter of receiver unit cable B to the surrounding
cables with the small binder (included with the standard parts)
so that it does not contact other electrical parts.
