1. INTRODUCTION
This User Manual provides general installation and use information regarding the Marelli Motori
regulator whose code is reported on the cover and inside the document, mounted on Marelli Motori
generator types indicated in Chap. 3.
Before starting the generator and performing any type of regulation operation, carefully and
completely read all of the instructions contained in this manual.
IMPORTANT NOTE: This User Manual not intended to cover all of the possible application or
installation variations nor to provide data or information to support every possible contingency. The
connection diagrams provided with the generator, its Use and Maintenance Manual and any
additional information provided by qualified Marelli Motori technical personnel supplements and
completes this manual.
In particular, the diagrams reported in this document provide only an example of the connection
and operation mode for the device; these do not cover all possible application cases and are not a
substitute for the connection diagrams normally provided with the generator.
If further application information becomes necessary, please contact Marelli Motori Services.
2. SAFETY PRECAUTIONS
ATTENTION: DO NOT TOUCH THE CONTROL MODULE WHEN IT IS UNDER POWER.
When the control module is under power (or the machine is in rotation) the upper
part of the device (connection side) and all parts electrically connected to it contain
lethal voltage. There could be also components with high temperatures that are
dangerous in the event of direct contact during normal operation on the component
module.
Any operation on the cabling and/or mechanical installation of the regulator must be
performed by qualified and informed personnel, with the generator halted and
making sure that a sufficient amount of time has passed for the regulator
components to have cooled down to a temperature that is not dangerous to personal
safety.
Marelli Motori denies any responsibility for damage to the regulator, system or people, for loss of
profit or money, or for system shutdowns caused by the failure to observe the safety and/or
installation/use instructions reported in this User Manual.
