Connect all the available power factor correction banks using terminals from 1 to 5, as indicated for banks 1, 2 and 5.
For the components indicated in the figure (CT1, F1..5, FU2, T1, KM1..5, C1..5 and QS1), refer to the power factor
correction equipment manual and to the manual of the system on which the power factor controller is fitted.
As an alternative, the cogeneration system (COGENERATOR) can be connected in one of the three positions (1), (2)
and (3) shown in the figure. If the installation is made in points (1) or (2), the controller will also correct the power factor of
the cogeneration system and the cogeneration operating mode will have to be enabled. If the installation is made in point
(3), the controller will not correct the power factor of the cogeneration system, hence the relevant operation mode will not
have to be enabled. For equipment installation, refer to the relevant manual.
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. If
you wish to perform this procedure, turn off the cogeneration systems.
Once the auto-acquisition procedure is completed, turn on again the cogeneration systems and set the
Cogeneration parameter to “ON” if the cogeneration system is in (2) or (1). For further details, refer to Chap. 7.1.5 -
Cogeneration.
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).

5.1.3 Other Basic Connections
Other connections can be made based on network configuration. The controller and the controlled power factor
correction equipment can be connected to the following networks:
- Standard, single phase, with phase-neutral voltage at 230Vac or 400Vac, with or without VT;
- Cogeneration, single-phase, with phase-neutral voltage at 230Vac or 400Vac, with or without VT;
- Three-phase, with standard neutral with phase-neutral voltage at 230Vac or 400Vac, with or without VT;
- Three-phase with neutral in co-generation with phase-neutral voltage at 230Vac or 400Vac, with or without VT;
- Three-phase without standard neutral with phase-neutral voltage at 230Vac, with or without VT;
- Three-phase without neutral in co-generation with phase-neutral voltage at 230Vac, with or without VT.
For this type of connections, refer to the complete operating manual, available at the following link:
