※
Run transmission wiring between the indoor and outdoor units through a conduit to protect against external forces,
and feed the conduit through the wall together with refrigerant piping.
•
Decide the capacity of ELCB(or MCCB+ELB) by below formula.
The capacity of ELCB(or MCCB+ELB) X [A] = 1.25 X 1.1 X ΣAi
※ X : The capacity of ELCB(or MCCB+ELB).
※ ΣAi : Sum of Rating currents of each indoor unit.
※ Refer to each installation manual about the rating current of indoor unit.
• Decide the power cable specification and maximum length within 10% power drop among indoor units.
