• Connect a power cable of the outdoor unit after checking that R-S-T-N (3 phase 4 wire) is properly connected. (If the 380-415 V power
is supplied to the N phase, PCB and other electrical part will be damaged.)
• Communication cable between indoor and outdoor units and communication cable between outdoor units has no polarity.
• Arrange the cables with a cable tie.
※ ELCB and ELB must be installed since there is risk of electric shock or fire when they are not installed.
