Description; Transport And Storage - MarelliGenerators MJB 160 Instrucciones Y Advertencias De Seguridad

2. DESCRIPTION

These instructions refer to three-phase synchronous generators series MJB. Technical data and constructive details are given in the
catalogue.
In order to obtain the proper working of the generator it is necessary to read carefully all included instructions.
The generators MJB are synchronous generators, brushless type, self excited and self regulated, manufactured according to the
standards indicated on the name plate (IEC 34-1).
Degree of protection - characteristics
The protection degree of the generators and the rated data are shown on the name plate.
Frequency
The generators are suitable for operation at 50 and 60 Hz, according to the data reported on the name-plate: for correct operation
for 50 or for 60 Hz, it is necessary to verify that the settings of the voltage regulator are proper for the required operation and that the
use of the generator is in accordance with the values on the name-plate.
Accessories
According to the customer's order the generators can be equipped with accessories, such as anticondensation heaters, thermistors,
etc.

3. TRANSPORT AND STORAGE

The generator is shipped ready for installation. It should be carefully inspected on arrival in order to verify if damage has occurred
during transport; if any, they should be referred directly to the haulier (writing one note on the document of transport) and to
MarelliMotori if possible with photographic documentation.
For lifting and handling the purpose made eyebolts must be used.
The lifting eyes are designed to support only the weight of the generator and they are not to be used for lifting the complete
gen-set that incorporates the generator. Check that the lifting means available are suitable for the movement of all parts which
have to be handled. Check also that all the working conditions are suitable to operate without dangers for safety of personnel.
The eyebolts on the end - shield are to the alignment of the generator during the phase of coupling to the engine.
Following are the weight of the generators:

If the generator is not put into operation immediately, it should be stored in a covered area or in a clean, dry and vibration-free place.
For periods of inactivity for periods of longer than three months, perform the tasks for "prolonged periods of storage" (available on
request).
If it is stored in a damp ambient, the windings should be dried before using it.
The rolling contact bearings do not require maintenance during storage; periodic rotation of the shaft will help to prevent contact
corrosion and hardening of the grease.
