9. CONNECTING DIAGRAMS
DANGER!
Only specially instructed personnel must carry out connec�on and repair ac�vi�es.
Each person involved in the installa�on and commissioning of the S2022 has to have received the
appropriate training or instruc�ons and has thoroughly read and clearly understood the safety instruc�ons
reported in this manual.
9.1 Introduc�on
Basically, the S2022 AVR needs:
-
A power supply source connected between L1, L2, L3
-
A sensing input source, connected between 0 and 115V or 0 and 490V
-
The connec�on of the exciter, between - and +
Following diagram shows a connec�on example of 3ph brushless alternator with internal 1ph auxiliary winding:
IMPORTANT
!
CT has always to be connected in quadrature compared the sensing voltage. This means:
-
With sensing voltage between L1 and L3, install the CT on phase L2 (as above)
-
With sensing voltage between L1 and L2, install the CT on phase L3
-
With sensing voltage between L2 and L3, install the CT on phase L1
