4.1.1 Panel Constructive Aspects
The panel is made with steel sheets painted and processed (cutting, holes, folding, chemical treatment, painting
and finishing) by WEG, ensuring the quality in all the levels of the manufacture process. The inverter parts that
are not painted are zinc plated or have another suitable treatment in order to assure their resistance against
corrosion.

The MVW3000 panel is supplied, in its standard structure, with degree of protection IP41 (openings smaller than
10 mm and protected against ingress of vertical drops). They can be supplied with distinct degrees of protection
according to the customer’s needs.
The panel cooling is done by means of forced convection. The air enters through the opening on the panel front
doors, goes through the transformer windings and also the power heatsinks located in each power cell. The
hot air leaves through the top do painel, of the panel, where the exhaust fans are located, allowing maintenance
without the need to open the inverter doors.
