Generators, whether in emergency or in continuous operation, must necessarily be equipped with documents that permit their use, installation and identification.

What are the documents that should be provided, be it a new generator or a second-generation generator?

In EU countries having a generator without documents is like having a serious problem!

Installation, Operation, Maintenance Manual.

The manufacturer for each machine produced gives a user manual and maintenance that allows the use of the product in a correct and safe way.

The manual is that document (paper or digital) that each operator should read before installing or in any case before using the generator set.

Engine, Alternator, and Other Component Manuals.

It is not essential to have a specific manual for each generator component, except for specific cases. Generator generator usually provides the engine and alternator operating manual.

Manufacturers of diesel engine generators distinguish the manuals in different types, such as the user from the OEM or the workshop manual.

Single-functional and functional diagrams of the control panel.

Together with manuals and other documents, the connection diagram for power conductors and control and control logic (especially in the case of automatic generating sets) is always provided.

It is good practice in the case of purchasing a generator that is used, check that the components and electrical connections are faithfully in line with the manufacturer's drawings. This is to safeguard the unhealthy purchase of tamper-evident machines and therefore no longer in compliance.

Assembly and installation drawings.

The obligation to supply designs of the generating set is defined in the contractual terms. An assembly diagram or a definite design is also known as "as build".

Documentation of any tests carried out.

A capitalized "C" builder performs functional testing and is responsible for all generating sets produced while others perform sample testing to limit production costs that inevitably affect the cost of the product.

Factory testing is a guarantee for the buyer because it minimizes the possibility of failure at commissioning.

In an optimum and real-time quality management system, testing allows any non-compliance to be handled before it can be transmitted to the final customer.

There is no obligation to provide the document certifying the generator's working test, which in any case is a part document.

It is important to distinguish the Test Report from the Test Certificate. The first can be provided free of charge upon request, while for the second one may be provided for a fee.

List of recommended replacement parts for commissioning.

It is necessary to dispose of a myth concerning the parts needed for commissioning: in 90% of cases there are no "necessary" parts for commissioning a generator. In the remaining 10%, these are consumable or specific parts for a particular application.

Warranty certificate.

A generator has a manufacturer's minimum guarantee of 12 months. The warranty certificate is required for the activation of the warranty, since once it is compiled and returned by PEC or recommended, it is a certain date of activation of the guarantee and allows the manufacturer to activate the guarantees of the various components.

Activating late warranty may be a problem, as most manufacturers set a maximum time limit between the delivery of the generator and its activation.

Certificate of conformity.

The purpose of the certificate of conformity is to ensure the free movement of goods within the European Union.

The document is always mandatory, and it is important to clarify some points:

A) Must be supplied in conjunction with the generator set. He must accompany the generator throughout his life.

(B) If the generator is produced outside the EU, the certificate of conformity must be issued by a Community entity, so if you decide to buy a product made in China (for example) then it is good to make sure that the importer has provided To issue the certificate.

(C) The importer entering the Community market shall be solely responsible for the marking and the relevant document.

By doing so, we see the data that must contain a certificate of conformity.

The EC declaration of conformity must contain the following elements:

- the name and address of the manufacturer or his authorized representative established within the Community;

- the name and address of the person holding the technical documentation;

- description of the equipment;

- the conformity assessment procedure followed and, where applicable, the name and address of the notified body which carried it out;

- sound power level guaranteed for the equipment;

- referral to this directive;

- declaration of conformity with the requirements of this directive;

- where applicable, the declaration of conformity and the other community directives applied;

- the place and date of the declaration;

- details of the person empowered to sign the legally binding declaration for the manufacturer or his authorized representative established within the Community.
