5. WIRING
Before starting installation work, turn off the power of this unit and the
connection destination. Do not turn on the power again until installation
is completed. Otherwise, it will cause electric shock or fi re.
2
Use the accessories or specifi ed connection cable. Do not modify power
2
supply cable and connection cables other than those specifi ed, do not
2
use extension cables, and do not use independent branch wiring. It may
1
cause electric shock or fi re.
Install the connection cables securely to the terminal block. Confi rm that
external force is not applied to the cable. Use connection cables made
of the specifi ed cable. If intermediate connection or insertion fi xing are
imperfect, it will cause electric shock, fi re, etc.
When connecting the connection cable, route the cables so that the
cover of this unit is securely fi xed. If the cover is imperfectly fi xed, it may
cause fi re or overheating of the terminals.
Perform earth (ground) work positively. Do not connect the earth (ground)
cable to a telephone cable, water pipe, or conductor rod.
Always fasten the outside covering of the connection cables with the
cable clamp. (If the insulator is chafed, electric leakage may occur.)
Perform all wiring works so that the user does not touch the wiring. Do-
ing so will cause injury or electric shock.
If any cable is damaged, do not repair or modify it yourself. Improper
work will cause electric shock or fi re.
Do not bind the remote controller cable and the external input cable
together with or parallel to the power supply cable of the indoor and
outdoor units. It may 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, fi re, or electric shock.
Install the indoor and outdoor units, power supply cable, connection
cable and remote controller cable 1 m (40 in.) away from television and
radio to avoid distorted images and noise. Otherwise, a malfunction
could result.
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 fi re.
Confi rm the name of each unit and name of each terminal block 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 fi re.
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 earth (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.
