is 'Connecting cable'. Power cable is a cable which is used to supply external electricity to the
outdoor unit. This cable is generally connected between external power source (such as main
electric power distribution panel of user's house) and the outdoor unit. Connecting cable is, on
the other hand, used to connect between the outdoor unit and the indoor unit to supply electric
power to the indoor unit and to establish the communication between the outdoor unit and the
indoor unit.
