• Refer to table below for specifications of field wire.
NOTE
1. The H05VV above is equivalent to the YZW-type common rubber sheath soft wires as specified in GB5013.
2. Shield wire materials may be used for transmission wiring, but they should comply with the standards. (Refer to Note 6 of “Precau-
tions When Doing Wiring Work”)
3. Select the electrical wire for power supply wire in accordance with the standards of the given nation and region.
4. Allowable length of transmission wire between indoor/outdoor units and between the indoor unit and the remote controller is as fol-
lows.
(1) Outdoor unit - Indoor unit: Max. 1000 m
(2) Indoor unit - Remote controller: Max. 500 m
5. Insulated thickness; 1mm or more.
• Remote controller cords.
Connect the cords to the remote controller terminal board (X3M P1, P2), no polarity, inside the control box. In doing this, fully
secure the cords using clamps.
• All wires should go through the bushes at the bottom of the control box.
• Ground wire from the unit to the control box.
Connect the grounding terminal of the unit with that of the control box. Secure the wires completely with clamps during connection.
NOTE) This unit is not equipped with the function of constant temperatures by means of the remote controller.
<PRECAUTIONS>
• Do not contact wires with gas or liquid piping. Be sure to insulate piping completely. (Refer to Fig.12-2)
• Check that the wires are not trapped in the control box lid or service cover.
• Do not clamp remote controller cords together with wires connecting the units together. Doing so may cause malfunction.
• Do not connect electric wires of different specifications to the same supply terminal.
(Loosing of the connecting terminal may cause over-heating.)
• Weak current wires (for remote controllers and transmission) and strong current wires (ground and power cords) outside the air
conditioner should not be mixed and should be separated by at least 50 mm. Otherwise electrical interference (external noise)
could cause malfunction or failure.
• In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so that outside forces are
not applied to the terminals.
CAUTION
• Paste washer or putty on the wire through hole in order to prevent water or insects from entering the control box. Otherwise it may
cause short circuits within the control box.
<Methods of wiring units and cords>
(Refer to Fig.15)
• All wires must be wired through bushes at the bottom of control box.
