GENERAL SAFETY WARNING

The generators which are the subject of these "instructions" are components designed for use in industrial areas (machines/plants) and
therefore cannot be treated as retail goods.
This documentation consequently contains information that is only suitable for use by qualified personnel. It must be used in compliance
with the regulations, laws and technical Standards in force and cannot under any circumstances take the place of plant standards or
additional prescriptions, including any which are not legally enforceable, which have been issued for the purpose of ensuring safety.
Machines built to customer specifications or with constructional differences may differ in detail from the generators described herein. If
you encounter any difficulties please do not hesitate to contact Marelli Motori, specifying:
- the type of machine
- the full code number of the generator
- the serial number
DANGER
Electric rotating machines have dangerous parts: when operating they have live and rotating components. Therefore:
- improper use
- the removal of protective covers and the disconnection of protection devices
- inadequate inspection and maintenance
can result in severe personal injury or property damage.
The person responsible for safety must therefore ensure that the machine is transported, installed, operated, maintained and repaired
by qualified personnel only, that must have:
- specific training and experience
- knowledge of applicable standards and laws
- knowledge of the general safety regulations, national and local codes and plant requirements
- the skill to recognise and avoid possible danger.
All maintenance and inspection operations must be carried out only with the authorisation of the person responsible for
safety, with the machine at a standstill, disconnected from the supply (including the auxiliary circuits such as the anti-
condensation heaters).
As the electric machine is a product to be installed in industrial areas, additional protective measures must be taken and assured
by the person responsible for the installation, if stricter protection conditions are required.
