Power supply cable system connection
Power supply cable system connection depends on the methods of communication between the indoor
unit and outdoor unit. For the HyperLink (M1M2) communication method, indoor units are allowed to have
independent power supplies. For other communication methods, indoor units should be provided with
uniform power supplies.

Indoor units are provided with independent power supplies*, which are wired as follows:

CAUTION
When the indoor units are provided with independent power supplies, the indoor units in the same refrigerant
system should be V8 indoor units*, and the communication between indoor units and outdoor unit adopts a
HyperLink (M1M2) with an independent power supply.
This connection method has the function of an independent power supply, so in the same refrigerant system, the
number of indoor units must not exceed 30 sets, and a maximum of only two repeaters may be installed*.
One repeater shall be added for every 10 indoor units or a communication wire length of 200m added.
