Maximum power supply distance is the distance in which a power supply unit (or an outdoor unit designated as a power

supply unit) is capable of supplying power to other units on the receiving end, such as remote controllers and indoor units.

Note

*1 The ME remote controller wiring length ( 3, 8) should be 10 m (32 ft) or less.

The length that exceeds 10 m (32 ft) needs to be included in the maximum distance to the farthest unit (500 m/1,640 ft) and

the maximum power supply distance (200 m/656 ft).

If the ME remote controller wiring length ( 3, 8) is 10 m (32 ft) or less, it does not need to be included in the distance to the

farthest unit or the power supply distance.
