*1. A breaker with at least 3 mm contact separation in each poles shall be provided. Use non-fuse breaker (NF) or earth leakage breaker (NV).
*2. Max. 45 m
If 2.5 mm 2 used, Max. 50 m
If 2.5 mm 2 used and S3 separated, Max. 80 m
For RP100, 125, 140Y application, use shield wires. The shield part must be grounded with the indoor unit OR the outdoor unit, NOT with both.
*3. The 10 m wire is attached in the remote controller accessory.
*4. The figures are NOT always against the ground.
S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are NOT electrically insulataed by the transformer or other device.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Power supply cords and Indoor/Outdoor unit connecting cords shall not be lighter than polychloroprene sheathed flexible cord. (Design 245 IEC 57)
3. Install an earth longer than other cables.
Warning:
In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power line
and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals when the power is
energized. If isolator should be used between indoor unit and outdoor unit, please use 3-poles type.
