1 - RECEIPT
1.1 - Standards and safety
measures
Our alternators comply with most
international standards.
See the EC declaration of incorporation on
the last page.
1.2 - Inspection
On receipt of your alternator, check that it
has not suffered any damage in transit. If
there are obvious signs of damage, contact
the carrier (you may be able to claim on their
insurance) and after a visual check, turn the
machine by hand to detect any malfunction.
1.3 - Identification
The alternator is identified by means of a
nameplate fixed on the machine (see
drawing).
Make sure that the nameplate on the
machine conforms to your order.
The machine name is defined according to
various criteria, for example:
LSA VS 40 S3 J44-30/4
• LSA: Name used in the PARTNER range
VS: Variable speed
• 40 : Machine type
• S3: Model
• J: Excitation system (J: SHUNT)
• 44-30/4 : Winding number/number of
poles
1.3.1 - Nameplate
So that you can identify your machine
quickly and accurately, we suggest you fill in
its specifications on the nameplate below.
1.4 - Storage
Prior to commissioning, machines should
be stored:
- Away from humidity (< 90%); after a long
period of storage, check the machine
insulation (section 3.2.1). To prevent the
bearings from becoming marked, do not
store in an environment with significant
vibration.
1.5 - Applications
These alternators are mainly designed to
produce direct current electricity in the
context of applications involving the use of
generators for charging batteries.
1.6 - Contraindications to use
Use of the machine is restricted to operating
conditions (environment, speed, voltage,
power, etc.) compatible with the
characteristics indicated on the nameplate.
