Model
All Indoor Units
RASC-5HNE
RASC-10HNE
The above wire sizes marked with  are selected at the maximum current of the unit according to the European Standard,
EN60335-1.
The above wire sizes marked with  are selected at the maximum current of the unit according to the wire, MLFC (Flame
Retardant Polyflex Wire) manufactured by HITACHI Cable Ltd. Japan.
In case that the power cables are connected in series, add each unit maximum current and select according to the next table.
