Hi all sifus, recently I want to install a Panasonic 4 way 3HP inverter cassette at my living room. My question is, is it true that the power source need to be at the outdoor unit instead of indoor unit? As the installer ask me to pull another 3 cable to outdoor (Total become 7 cables).

Thank you very much for the prompt response, some technician say only need 4 cables can install, or it is better to go for 7 cables? Thank you.
