Corrective maintenance

Continuous development within the scope of product maintenance

Inverter components are being continuously developed within the scope of product

maintenance. Product maintenance includes, for example, measures to increase the

ruggedness or hardware changes which become necessary as components are discontinued.

These further developments are "spare parts-compatible" and do not change the article

In the scope of such spare parts-compatible ongoing development, plug connector or

connection positions are sometimes slightly modified. This does not cause any problems when

the components are properly used. Please take this fact into consideration in special

installation situations (e.g. allow sufficient reserve regarding the cable length).
