*1. A breaker with at least 3 mm contact separation in each pole shall be provided. Use earth leakage breaker(NV).
*2. Refer to “8-3. INDOOR – OUTDOOR CONNECTING CABLE”.
*3. The 10 m wire is attached in the remote controller accessory.
*4. The figures are NOT always necessarily the voltage to ground.
S3 terminal has 24 V DC
against S2 terminal. However between S3 and S1, these terminals are NOT electrically insulated 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 60245 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-pole type.

Caution: Be sure to install N-Line. Without N-Line, it could cause damage to the unit.
Make sure that the current leakage breaker is one compatible with higher harmonics.
Always use a current leakage breaker that is compatible with higher harmonics as this unit is equipped with an inverter.
The use of an inadequate breaker can cause the incorrect operation of inverter.
