1. SAFETY INSTRUCTIONS
Before using the generating set it is
necessary to read the generating set and
alternator "Use and Maintenance Manual"
and to follow the recommendations
below.
⇒ Safe and efficient performance may be achieved
only if the machines are used correctly, in com-
pliance with the instructions provided by the
relevant use and maintenance manuals and safety
regulations.
⇒ An electric shock may cause serious personal
- 12 -
injury or even death.
⇒ Do not remove either the terminal board cover or
the alternator protection grid before the alterna-
tor has come to a complete stop and the generat-
ing set starting system has been deactivated.
⇒ Only competent and qualified personnel should
carry out the maintenance of the generating set.
⇒ 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 generating set, needs to
be lifted from the floor, the operators must also wear a
safety helmet.
The person responsible for the installation
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 regula-
tions (earthing, contact protection, explo-
sion and fire safety measures, emergency
stop, etc....)

2. ALTERNATOR DESCRIPTION

The SL series is comprised of three-phase (SLT) and
single-phase (SLS) brushless, four pole alternators with
exciter, equipped with an automatic voltage regulator.
They are manufactured in compliance with EN 60034-1,
EN 60204-1, EN61000-6-2, EN61000-6-4, EN 55014-1,
EN 55011 specifications, as well as with the 2006/95/CE,
2004/108/CE directives.
Ventilation: Axial with air inlet on the non-drive end side .
Protection: IP 23 standard.
Direction of rotation: Both directions are allowed.
Electrical features: Both the stator and rotor insulation
components are made from class H materials. The wind-
ings are tropicalized.
Power values: Refer to the following conditions: ambient
temperature up to 40°C, altitude up to 1000m above sea-level
and continuous duty at cos φ = 0.8.
