The specifications shown in the above table are for units without heaters. For units with heaters, refer
to the installation instructions or the construction instructions of the indoor unit.
Switchgear of Circuit breaker capacity which is calculated from MAX. over current should be chosen
along the regulations in each country.
The cable specifications are based on the assumption that a metal or plastic conduit is used with no
more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling
outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation
in effect in each country.
