Sequential start

The outdoor unit PC board (A1P) is factory set at "Sequential start

available".

Setting the cool/heat operation (heat pump unit only)

1 Performing cool/heat setting with the remote controller

connected to the indoor unit.

Keep the cool/heat selector switch (DS1) on the outdoor unit PC

board at the factory setting position IN/D UNIT. (See ﬁgure 22)

2 Performing cool/heat setting with the cool/heat selector.

Connect the cool/heat selector remote controller (optional) to the

A/B/C terminals and set the cool/heat selector switch (DS1) on

the outdoor unit PC board (A1P) to OUT/D UNIT. (See ﬁgure 25)

8.8. Field line connection: power wiring

The power cord must be clamped to the plastic bracket using ﬁeld

supplied clamp material.

The green and yellow striped wrapped wires must be used for

grounding. (See ﬁgure 21)

8.9. Wiring example for wiring inside unit

See ﬁgure 26.

1 Remote controller

1 Cool/heat selector

For low-noise operation, it is necessary to get the optional

'External control adaptor for outdoor unit' (DTA104A61/62).

For details, see the installation manual attached to the

adaptor.

1 Power supply (400 V, 3 N~50 Hz)

2 Fuse

3 Earth leakage breaker

4 Grounding wire

5 Power supply terminal block

6 Connect each power wire

RED to L1, WHT to L2, BLK to L3 and BLU to N

7 Ground wire (GRN/YLW)

8 Clamp the power wire to the plastic bracket using a ﬁeld supplied

clamp to prevent external force being applied to the terminal.

9 Clamp (ﬁeld supply)

10 Cup washer

11 When connecting the earth wire, it is recommended to perform

curling.

■ When routing ground wires, secure clearance of

50 mm or more away from compressor lead wires.

Failure to observe this instruction properly may

adversely effect correct operation of other units

connected to the same ground.

■ When connecting the power supply cord, the earth

connection must be made before the current-carrying

connections are established. When disconnecting the

power supply cord, the current-carrying connections

must be separated before the earth connection is.

Length of the conductors between the power supply

cord anchorage and the terminal block itself must be

such that the current-carrying conductors are

tautened before the earthing conductor is in case the

power supply cord is pulled loose from the cord

anchorage.

Precautions when laying power wiring

■ Do not connect wiring of different thicknesses to the

power terminal block. (Slack in the power wiring may

cause abnormal heat.)

■ When connecting wiring which is the same thickness,

do as shown in 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 table below for tightening torque for the

terminal screws.

Recommendations when connecting the ground

When pulling the ground wire out, wire it so that it comes

through the cut out section of the cup washer. (An

improper ground connection may prevent a good ground

from being achieved.) (See ﬁgure 21)

1 Electric wiring

2 Wiring between units

3 Clamp to the electric box with ﬁeld supplied clamps.

4 When routing out the power/ground wires from the right side:

5 When routing the remote control cord and inter-unit wiring, secure

clearance of 50 mm or more from the power wiring. Ensure that

the power wiring does not contact any heated sections ( ).

6 Clamp to the back of the column support with ﬁeld supplied

clamps.

7 When routing out the inter-unit wirings from the opening for piping:

8 When routing out the power/ground wires from the front:

9 When routing out the ground wires from the left side:

10 Grounding wire

11 When wiring, pay attention not to detach the acoustic insulators

from the compressor.
