How to connect wiring
(See figure 10)
■
Inter unit wiring
Remove the control box lid (1) and connect the inter unit wiring
terminal block inside with the matching numbers and connect
the ground wire to the grounding terminal. While doing this, pull
the wires inside through the hole in the casing and clamp the
wires along with other wires using a clamp as indicated in the
figure.
■
Remote controller wiring
Remove the control box lid (1) and pull the wires inside through
the hole in the casing and connect to the remote controller wiring
terminal block. Securely fix the wiring using a clamp as indicated
in the figure.
■
After connection
Attach the small sealing (supplied with the unit) around the
cables to prevent infiltrating of water from the outside into the
unit. If two or more cables are used, divide the small sealing into
the required number of pieces and wrap them around all the
cables.

Precautions
1
Observe the notes mentioned below when wiring to the power
supply terminal board.
-
Use a round crimp-style terminal for insulation sleeve for
connection to the terminal block for wiring the units. When
none are available, follow the instructions below.
-
Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
-
When clamping wiring, use the clamps (delivered with the
unit) to prevent outside pressure being exerted on the wiring
connections. Tie up firmly. When doing the wiring, make sure
the wiring is neat and does not cause the control box to stick
up. Close the cover firmly.
-
When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely to
the terminal. Lock the wire down without applying excessive
force to the terminal. Use torques according to the table
below.
-
When attaching the control box lid, make sure not to pinch
any wires.
-
After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
supply) thus to prevent small animals or dirt from entering the
unit from outside and causing short circuits in the control box.
2
Keep total current of crossover wiring between indoor units less
than 12 A. Branch the line outside the terminal block of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm
2
(Ø1.6).
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3
Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
4
Remote controller wiring should be located at least 50 mm away
from inter unit wiring and other wiring. Not following this
guideline may result in malfunction due to electrical noise.
5
For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6
Never connect the inter unit wiring to the remote controller wiring.
This mistake could damage the entire system.
7
Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worst case, electric shock
or fire.
