* The AVR-A-OPT-07E regulators, the external potentiometer function is replaced by Analog Input.
The connection must be made respecting the voltage specified for the model. See sensing voltage on the
identification label or, in case of doubt, consult the technical service;
For connection of a generator of three voltages (220/380 / 440Vac - YY/Y/Y) and tensions of 380 or 440Vac,
connecting in means of the coils.
If no potentiometer is connected, keep terminals 6 and 7 jumped (short-circuited).
ATTENTION
1.
Before connecting the regulator to the alternator, check installation manual and the nominal reference
voltage;
2.
If the reference voltage is not equal to the alternator output voltage, do not make the connections
without first contacting the service department.

CONNECTION FOR AVR MOUNTED IN THE METALLIC BOX

1- The connection must be made respecting the voltage specified for the model.
See supply voltage on the identification label or in case of doubt consult the technical assistance service;
2- The connection must be made respecting the voltage specified for the model.
See sensing voltage on the identification label or in case of doubt consult the technical assistance service;
3- CT/In 5A, connection needed only for parallel operation;
4- Connection for potentiometer of the voltage fine adjustment (optional);
5 Connecting to control of the voltage for signal ± 9 VDC (AVR-A-OPT-07E);
6- Use Jumper version only no pot and no analog input;
7- We suggest installing the fuse (35 or 50A, depending on model) at the entrance of the exciter (terminals 3 and 4).
