(When using 2 remote controllers, the maximum wiring length for the remote controller cables is 200 m, 656 ft.)
*3. The figures are NOT always against the ground.
S3 terminal has 24 V DC / 28 V DC against S2 terminal. However, between S3 and S1, these terminals are not electrically insulated by the transformer or other device.
*4. It depends on the outdoor unit.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Power supply cords and indoor unit/outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord.
(Design 60245 IEC 57)
3. Use copper supply wires.
4. Use UL wires rated 300 V or more for the power supply cords and the indoor unit/outdoor unit connecting cords.
5. Install an earth longer than other cords.
6. Indoor and outdoor connecting wires have polarities. Make sure to match the terminal number (S1, S2, S3) for correct wirings.
7. Wiring for remote controller cable shall be apart (5 cm, 2 inch or more) from power source wiring so that it is not influenced by electric noise from
power source wiring.
