10 English
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 17-1, 2)
• When passing wiring through the knock holes, remove burrs around
the knock holes and protect the wiring with protective tape.
(Refer to figure 17-1, 2)
• If small animals might enter the unit, block off any gaps (hatching
parts in figure 17-1, 2) with material (field supply).
7-4 Transmission Wiring Connection Procedure
• Referring to figure 18 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 18)
1. EL. COMPO. BOX (1)
2. EL. COMPO. BOX (2)
3. Do not open the EL. COMPO. BOX (2) lid.
(There are no work when installation)
4. Never connect the power wire.
5. To outside unit of other system
6. Use duplex wires (No polarity)
7. BS unit
8. Indoor unit
9. Indoor unit (Cooling only)
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 ~ , see figure 18)
should be done within the following limitations.
If they are exceeded, transmission problems may occur.
Between outside unit and BS (or indoor) unit
Between BS unit and indoor unit
Between outside unit and outside unit of other systems
Max. wiring length : 3280 ft
Max. total wiring length : 6560 ft
Max. no. of branches : 16
[Note]
No branch is allowed after branch (See figure 19)
Max. no. of outside units of other system
that can be connected : 10
(Refer to figure 19)
1. Branch
2. Branch after branch
Between outside unit and outside unit of same system
Max. wiring length : 100 ft
• The transmission wiring inside the EL.COMPO.BOX should be
secured using the clamp (1) as shown in figure 20.
(Refer to figure 20)
1. In the EL.COMPO.BOX
2. Retain to the EL.COMPO.BOX with the accessory clamp (1).
3. Vinyl tube (accessory)
• 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 21.
(Refer to figure 21)
1. Suction gas pipe
2. HP/LP gas pipe
3. Liquid pipe
4. Insulation material
5. Finishing tape
6. Transmission wiring
• Wiring to other systems should be connected to terminals F1 and F2
(TO OUT/D UNIT) on the PC-board of the EL. COMPO. BOX(1).
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 22.
• 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 22)
1. Power supply
(MODEL PAYD:3~460V 60Hz)
(MODEL PATJ:3~208-230V 60Hz)
2. Earth leakage circuit breaker
3. Branch switch, earth leakage circuit breaker
4. Ground wire
5. EL. COMPO. BOX (1)
6. EL. COMPO. BOX (2)
7. Do not open the EL. COMPO. BOX (2) lid.
(There are no work when installation)
8. Attach insulation sleeves
9. Power supply terminal block
10. Ground terminal
11. Clamp (1) (accessory)
12. Vinyl tube (accessory)
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.
