4.5.6 Diesel Generator auxiliary contact OPTIONAL
Auxiliary contact from the Diesel Generator on terminals XD-1/2.
A normally open contact must be used; the contact must close when the diesel generator is
operating.
The microprocessor will acquire the status of the contact and, upon the rectifier start-up, it will
enable the "Diesel Mode" operation, that is the operation at reduced DC voltage in order to
reduce the power drawn from the AC line.
