• Refer to the unit nameplate for rating current.
• Decide the capacity of ELCB(or MCCB+ELB) by below formula.
• 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 )
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.
