 Run transmission wiring between the indoor and outdoor units through a con-
duit 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 ∑ Ai
 X : The capacity of ELCB(or MCCB+ELB).
 ∑ Ai : 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.
