1. SAFETY INSTRUCTIONS
Before using the generating set it is ne-
cessary to read the «Use and Maintenance
Manual» of the generating set and the
alternator, and to follow the recommenda-
tions below:
⇒ ⇒ ⇒ ⇒ ⇒ Safe and efficient functioning can be
achieved only if the machines are used cor-
rectly, according to the instructions provided
by the relevant use and maintenance manu-
als, and safety recommendations.
⇒ ⇒ ⇒ ⇒ ⇒ An electric shock can cause serious per-
sonal injuries and even death.
⇒ ⇒ ⇒ ⇒ ⇒ Do not remove the terminal board cover and
the alternator's protection grid before the
alternator has come to a complete stop, and
before deactivating the starting system of the
generating set.
⇒ ⇒ ⇒ ⇒ ⇒ The generating set maintenance must be
carried out exclusively by competent and
qualified personnel.
⇒ ⇒ ⇒ ⇒ ⇒ Do not wear loose garments when working
near the generating set.
People in charge of operating the set must always
wear protective gloves and safety shoes.
In the event that the generator, or the whole gener-
ating set need to be lifted from the floor, the opera-
tors must wear a safety helmet as well.
Safety notices used in this manual have the fol-
lowing meaning:
Important!: it refers to dangerous or risky
operations that may damage the equipment;

- 17 -
Danger!: it refers to an immediate risk that
may cause serious personal injuries or death.
The final installer of the generating set
must make sure that all the necessary
safety arrangements are in place in order
to make the whole plant compliant with current
local safety regulations (earthing, contact pro-
tection, explosion and fire safety measures,
emergency stop, etc....)
2. ALTERNATOR DESCRIPTION

brushless alternators with exciter. They can be
equipped with automatic voltage regulator (E1X...E),
compound (E1X...K) or compound and electronic
mixed regulation (E1X...KE).They are manufactured
in compliance with EN60034-1, EN50081-1,
EN61000-6-4 specifications, as well as with the di-
rectives no.73/23 CEE, EMC 89/336 CEE and 98/
037 CEE.
Ventilation: Axial with air inlet on the non-drive end side.
Protection: Standard IP 21. IP 23 on request.
Direction of rotation: Both directions are allowed.
Electrical features: Insulation components are
made with class H material, for both stator and ro-
tor. Windings are tropicalized.
Power values: They refer to the following conditions:
ambient temperature up to 40°C, altitude up to 1000 m.
above sea-level, continuous duty at cosϕ= 0.8.
