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.
※
Power supply cords of parts of appliances for outdoor use
shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 57 /
CENELEC: H05RN-F or IEC:60245 IEC 66 / CENELEC: H07RN-F)
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.
