*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. Use an earth wire which is longer than the other cords so that it will not become disconnected when tension is applied.

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.
· Turn on the main power when the ambient temperature is - 20°C or higher.
· In below - 20°C condition, it needs at least 4hr stand by to operate in order to warm the electrical parts.
