(1) Values at the unit's maximum operating condition (as shown on the unit's nameplate).
(2) The value decreases as the input power is reduced
(3) May vary depending on the short-circuit ratio of the installation.
The THDi value increases as the input power drops. However, the effects on the installation are greater when the current is at its maximum. For this reason,
the installation's compliance with standards relating to voltage harmonics (for example, the IEC standard 60000-2-4) must usually be checked at the maximum load
condition, to ensure the other operating scenarios are covered.
(4) Operating current of the biggest compressor + fan current + starting current of the smallest compressor.
Starting current values used for the compressor are : 06ZCE1-H3AA06013 = 40A ; 06ZFC2-3AA06013 = 50A ; 06ZJG3-3AA06013 = 80A.

(1) Values obtained at operation with maximum operating power input (data given on the unit nameplate)
(2) Value decreases when load lowers
(3) May vary according to the installation's short circuit ratio
THDi increases when load lowers. But the highest impact on the installation occurs when the current is maximum. Therefore compliance of the installation regarding
voltage harmonic distortion at PCC (per IEC61000-2-4 or other standard) shall be usually checked at max load in order to cover all load conditions.
(4) Operating current of the biggest compressor + fan current + starting current of the smallest compressor.
Starting current values used for the compressor are : 06ZCE1-H3AA06013 = 40A ; 06ZFC2-3AA06013 = 50A ; 06ZJG3-3AA06013 = 80A.
