●
Mode
In this parameter, the control algorithm that the device will use for harmonic filtering is selected, the
options are:

FREQ: Frequency Mode, Harmonic filtering based on the selection of harmonics to be neu-
tralised from 3 to 25.

TEMP: Temporary Mode, Harmonic filtering based on the instantaneous neutralisation of all
harmonics.
Do not use
Temporary mode
if the supplier has not recommended this for their instal-
lation. This method can cause resonance in certain installations.
● Enabled Functions
In this parameter, you can select the operating mode of the device, i.e., the functions that the device
performs during operation:

Harmonics
Enable this function so that the device performs the filtering of the current harmonics.

Phase balance
Enable this function so that the device performs the current balancing between phases.
