NOTE

Open the knock holes with a hammer or the like.

After knocking out the holes, we recommend you remove any burrs and 
paint them using the repair paint to prevent rusting. 

(Refer to figure 18-1, 2)

When passing wiring through the knock holes, remove burrs around 
the knock holes and protect the wiring with protective tape. 

(Refer to figure 18-1, 2)

If small animals might enter the unit, block off any gaps (hatching 
parts in figure 18-1, 2) with material (field supply).

7-4 Transmission Wiring Connection Procedure

Referring to figure 19 connect the transmission wiring between out-
side unit and indoor unit, outside unit and outside unit of other sys-
tem, outside unit and outside unit of same system.

(Refer to figure 19)

1.

Master unit (*)

2.

Sub unit (*)

3.

Outside unit A

4.

Outside unit B

5.

EL. COMPO. BOX (1)

6.

(Only RXYQ~PAYD)
EL. COMPO. BOX (2)

7.

(Only RXYQ~PAYD)
Do not open the EL. COMPO. BOX (2) lid.
(There are no work when installation)

8.

Never connect the power wire.

9.

To outside unit of other system

10.

Use duplex wires (No polarity)

11.

Indoor unit

(*) : The Outside unit that connect the transmission wiring to BS 

unit is Master unit of the multi system.
And the other units are Sub unit. (In this figure, Outside unit 
A is the Master unit.)
Check operation in installation work, Onsite settings and so 
on are done by operating the PC-board (A1P) of Master unit.

NOTE

Do not connect the power wiring to terminals for the transmission 
wiring. Doing so would destroy the entire system.

When connecting wires to the terminal block on the PC-board, too 
much heat or tightening could damage the PC-board. Attach with care.
See the table below for the tightening torque of the transmission wiring 
terminals.

Transmission wiring (About the symbol

should be done within the following limitations.
If they are exceeded, transmission problems may occur.

Max. wiring length

: 3280 ft

Max. total wiring length

Max. no. of branches

: 16

[Note] 
No branch is allowed after branch (

See figure 20

)

Max. no. of outside units of other system 
that can be connected

: 10

The transmission wiring inside the EL.COMPO.BOX should be 
secured using the clamp (1) as shown in figure 21.

Outside the units, the transmission wiring must be finished simulta-
neously with the local refrigerant piping, and wound with tape (field 
supply) as shown in figure 22.

Finishing tape

For multi system:
1. Transmission wiring between outside units in the same piping sys-

tem must be connected to terminals Q1 and Q2 (TO MULTI UNIT).
Connecting the wires to the F1, F2 (TO OUT/D UNIT) terminals 
results in system malfunction.

2. Wiring to other systems should be connected to terminals F1 and 

F2 (TO OUT/D UNIT) on the PC-board of the master unit. The 
outside unit that connected transmission wiring to indoor unit is 
the master unit. The others are sub unit.

7-5 Power Wiring Connection Procedure

Be sure to connect the power supply wiring to the power supply ter-
minal block and hold it in place using the included clamp as shown in 
the figure 23.

The L1, L2, L3 and N phases of the power wiring should be secured 
separately to the hook using the included clamp (1).

The ground wiring should be bound to the power wiring using the 
included clamp (1) to prevent outside force from being applied to the 
terminal area.

(Refer to figure 23)

(There are no work when installation.)

CAUTION

Be sure to use crimp-style terminal with insulating sleeves for con-
nections. (See the figure below.)

For wiring, use the designated power wire and connect firmly, then 
secure to prevent outside pressure being exerted on the terminal board.

Use an appropriate screwdriver for tightening the terminal screws. A 
screwdriver with a small head will strip the head and make proper 
tightening impossible.

Over-tightening the terminal screws may break them.
See the following table for the tightening torque of the terminal screws.

When pulling the ground wire out, wire it so that it comes through the 
cut out section of the cup washer. (See the figure below.) An improper 
ground connection may prevent a good ground from being achieved.
