*1. A breaker with at least 3.0 mm contact separation in each poles shall be provided. Use earth leakage breaker (NV).
*2. Max. 80 m Total Max. including all indoor/indoor connection is 80 m.
• Use one cable for S1 and S2 and another for S3 as shown in the picture.
• Max. 50 m Total Max. for PEA. Wiring size 3 × 1.5 (Polar).
*3. The 10 m wire is attached in the remote controller accessory.
*4. The fi gures 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 fl exible cord. (Design 60245 IEC 57)
3. Install an earth longer than other cables.
