NOTE
Alternators manufactured to meet the
standards referred in item 2.3.3 may be
different specific projects of the standard
alternators. Consult the alternator technical
documentation.

2.4 ENVIRONMENT FEATURES

In accordance with IEC 60034.1, and ABNT 5117, the
ambient operating conditions for which the alternators
were designed are the following:
1. Ambient temperature: – 15 ºC to + 40 ºC;
2. Altitude (a.s.l.): up to 1000 m;
3. Environment without the presence of aggressive
agents such as: salt spray, chemicals, etc.;
4. Environment according to the protection degree of the
alternator.
Special conditions of environment are described on the
rating plate and specific technical data sheet of the
alternator.
2.4.1

Harsh or marine environment

The industry standard alternator should not be used in
harsh environments, because this action is subject to
weather that can cause corrosion of mechanical parts and
decrease the insulation resistance of the windings and
consequently the burning of the alternator. In these
situations, WEG is not responsible for damage that may
occur on the alternator, depriving the product warranty
according to the warranty terms.
NOTE
Alternators applied in harsh environments
should be equipped with additional protection
against corrosion and poor insulation,
ensuring, when requested, to guarantee
performance of the product.
Is considered harsh environment: marine
environment or with high concentration of
salinity and / or high humidity, materials in
suspension that can be abrasive, and naval
application with high ambient temperature
variation. n these cases, please refer to WEG
I
for correct specification of the alternator to
the required application.

2.5 OPERATING CONDITIONS

For the warranty term of the product to be valid, the
alternator must operate according to the nominal data,
follow the standards and codes and the information
contained herein.
