7-4 Transmission Wiring Connection Procedure
• Referring to figure 19 connect the transmission wiring between
outdoor unit and indoor unit, outdoor unit and outdoor unit of other
system.
(Refer to figure 19)
1. EL. COMPO. BOX (1)
2. EL. COMPO. BOX (2)
3. Never connect the power wire.
4. To outdoor unit of other system
5. Use duplex wires (No polarity)
6. BS unit
7. Indoor unit
8. 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.
• All transmission wiring should use sheathed vinyl cord
0.75-1.25 mm
2
or cable (duplex).
• Transmission wiring should be done within the following limitations.
If they are exceeded, transmission problems may occur.
Between outdoor unit and BS (or indoor) unit
Between BS unit and indoor unit
Between outdoor unit and outdoor unit of other systems
Max. wiring length :1,000 m
Max. total wiring length :2,000 m
Max. no. of branches :16
[Note]
No branch is allowed after branch (See figure 20)
Max. no. of outdoor units of other system
that can be connected
: 10
(Refer to figure 20)
1. Branch
2. Branch after branch
• The transmission wiring inside the EL.COMPO.BOX (1) (right)
should be secured using the clamp (1) as shown in figure 21.
(Refer to figure 21)
1. In the EL.COMPO.BOX (1) (right)
2.
Retain to the EL.COMPO.BOX with the accessory clamp (1).
• Outside the units, the transmission wiring must be finished simul-
taneously with the local refrigerant piping, and wound with tape
(field supply) as shown in figure 22.
(Refer to figure 22)
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 unit. Connecting the
wires to the Q1, Q2 (TO MULTI UNIT) terminals results in mal-
function.
• The Q1, Q2 (TO MULTI UNIT) terminals of EL. COMPO. BOX (1)
(right) are connected to the Q1, Q2 (TO MULTI UNIT) terminals of
EL. COMPO. BOX (2) (left) by internal tansmission wiring. Do not
remove the internal transmission wiring.
7-5 Power Wiring Connection Procedure
• Be sure to connect the power supply wiring to the power supply
terminal 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)
1. Power supply (3N~ 380-415V 50Hz)
2. Earth leakage circuit breaker
3. Branch switch, Overcurrent 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)
Caution
• Be sure to use crimp-style terminal with insulating sleeves for
connections. (See the figure below.)
• For wiring, use the designated power wire and connect firmly,
then secure to prevent outside pressure being exerted on the ter-
minal 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.
• When two wires are connected to a single terminal, connect them
so that the rear sides of the crimp contacts face each other. Also,
make sure the thinner wire is on top, securing the two wires simul-
taneously to the resin hook using the included clamp (1).
7-6 Procedure for Wiring Inside Units
• Referring to figure 24, secure and wire the power and transmis-
sion wiring using the included clamp (1), (2), and (3).
• Wire so that the ground wiring does not come into contact with the
compressor lead wiring.
If they touch, this may have an adverse effect on other devices.
• The transmission wiring must be at least 50 mm away from the
power wiring.
• Make sure all wiring do not contact to the pipes (hatching parts in
the figure 24).
(Refer to figure 24)
1. Secure to the hook of column support using the acces-
sory calmp (1).
2. Electric conduit
3. When routing out the power/ground wires from the left side.
4. When routing out the transmission wiring from the open-
ing for piping.
5. When routing out the power/ground wires from the front.
6. Clear over 50 mm.
