*1.
The breaker shall be provided to ensure disconnection of all active phase conductor of the supply.
A breaker with at least 3 mm contact separation in each poles shall be provided. Use earth leakage beaker(NV).
*2. Refer to 9-3.
*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 insulated by the transformer or other device .
Notes: 1. Wiring size must comply with the applicable local and national code..
2. Power supply cables and Indoor/Outdoor unit connecting cables shall not be lighter than polychloroprene sheathed flexible cable.
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.
