INTRODUCTION
This Technical Note provides general installation and operating
information exclusively concerning the Marelli Motori regulator
code specified in the document, mounted on the Marelli Motori
synchronous generators specified in the next paragraph
“APPLICATION”.
Before the generator start and any types of regulation
operation, read carefully and completely this Technical Note.
IMPORTANT NOTE: It is not the intention of this document to
cover all the installation or connection diagram variations, nor
does this manual provide information for every possible
contingency. The connection drawings provided with the
generator, the generator user manual and all the technical
information provided by Marelli Motori Technical Personnel can
integrate this Note.
In particular, the connection drawings into this document are
provided only for explanation purposes. They do not cover all
the application cases and not substitute the connection
drawings usually provided with the generator.
Should further information be required, please contact After
Sales Department (see the reference at the end of the page).
SAFETY PRECAUTIONS
WARNING: when the regulation device is
energized (generator running), a lethal
voltage is present at the top panel
(connection side) and at all the parts electrically connected
to it. Furthermore, there are components into the card that can
reach high working temperatures, with high danger for the user
in case of direct contact.
Every wiring and/or mechanical installation
operation on the regulator must be performed only
in generator stop conditions, and only by skilled
personnel. Furthermore, pay attention to wait a time
interval sufficient for the device cooling-down.
Every regulation setting operation must be
performed with generator running in no load
conditions, by skilled personnel, using tools
suitable to assure the user safety (i.e. isolated screwdriver,
protection glasses and gloves).
Marelli Motori is under no liability for any damages which may
occur to the AVR, the plant or the persons, or for lost earnings,
or financial loss, or system stoppages, due to missed out
Technical Note reading (both safety and installation/operating
instructions).
