CAUTION: At first power-up of the system, if on the amperometric input there is a current exceeding 0.7% of the CT
secondary wiring Chap. 7.1.2 the auto-acquisition procedure will be automatically performed based on one of the
methods specified in Chap. 6. This procedure requires the essential parameters necessary for the first commissioning.
WARNING: If you want or if you need to edit the default parameters before auto-acquisition, do not connect the
current signal to controller (CURRENT terminals), or make sure that the current reading is equal to zero.
Then set parameters through the Setup Menu consistently with the indications given in Chap. 7.7.
NOTE 1: in case of blocking reactors, refer to the indications given in Chap. 8.9 - Presence of blocking reactors.
NOTE 2: the Re-connection time parameter must be set consistently with the indications given in the power factor
correction equipment manual. WARNING: Entering a time shorter than the recommended one can lead to equipment
and/or controller damage.
It is always possible to edit parameters even after the auto-acquisition and/or to repeat this latter using the Auto-
acquisition reset functions (Chap. 8.6.6) and Reset to factory settings (Chap. 8.6.7).
