General Instructions; Qualified People; Safety Instructions; Standards - WEG AG10 Series Installation, Operation And Maintenance Manual

2 GENERAL INSTRUCTIONS

Professionals who work with electrical installations, in either assembly, operation or maintenance, should be continuously
updated and be informed about rules and safety regulations governing the service and are advised to observe them strictly.
Before the initiation of any work, the responsible person must ensure that everything was properly noticed and alert
operators to the dangers inherent in the task to be performed. Alternators of this type, if used improperly or receive poor
maintenance, or when people do not receive the intervention of not qualified personnel may cause serious personal injury
and/or material damage. It is therefore recommended that these services be always performed by qualified people.

2.1 QUALIFIED PEOPLE

It is understood by people qualified those professionals
who, because of their training, experience, education level,
knowledge of relevant standards, specifications, safety
standards, accident prevention and knowledge of
operating conditions, have been authorized by their
leaders to carry out the work required and that can
recognize and avoid potential danger.
These qualified people must also know the first aid
procedures and be able to provide such service if
necessary.
It is assumed that all work of commissioning, maintenance
and repairs are done only by qualified people.

2.2 SAFETY INSTRUCTIONS

DANGER
During operation, these devices have
exposed energized or rotating parts, which
may have high voltage or high temperature.
Thus, the operation with open terminal boxes,
unprotected couplings, or incorrect handling
without considering the standards of
operation may cause serious injury and
property damage.
Those responsible for safety of the facility must ensure that:

Only qualified people perform installation and operation
of equipment;

These people have in hand this manual and other
documents provided with the alternator, as well as
perform the work strictly observing the instructions of
service, relevant standards and documentation of
specific products.
Failure to comply with installation standards and safety
may void the warranty.
Equipment for firefighting and first aid notices should be at
work in clearly visible and easily accessible places.
Please also notice:

All technical data about the applications permitted
(operating conditions, connections and installation
environment) contained in the catalog, documentation
of the application, operating instructions, manuals and
other documents;

The specific determinations and conditions to the
installation site;

The use of tools and equipment suitable for handling
and transport;

That protective devices of the individual components be
removed before installation.
The spare parts must be stored in an environment free of
vibrations, preventing falls and ensuring that they are
protected against aggressive and / or endanger the safety
of people.
