The value in parentheses beneath the minimum power cable thickness indicates the maximum cable length (m).

The outdoor-side power cannot be wired across multiple units.

The indoor-side wiring capacity is not included.

Note that it is not possible to draw general power from the indoor side.
When selecting an earth leakage circuit breaker for the power side, we recommend one that provides coodinated

protection.
The electrical installation shall comply with national and local wiring/installation requirements.

This equipment complies with EN/IEC 61000-3-11 provided that the system impedance Zmax is less than or

equal to the values corresponding to each model as shown in the table below at the interface point between
the user's supply and the public system. Consult with the supply authority for the system impedance Zmax.
Zmax 0.467 Ω
Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 5 or

3 *1.5 mm flexible cord. Type designation 60245 IEC57 (H05RN-F, GP85PCP etc.) or heavier cord.

Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F which conform to CENELEC

(HAR) rating specifications) or use the cables based on IEC standard. (60245 IEC57, 60245 IEC66)
