Corrective maintenance

9.1

Spare parts compatibility

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
number.
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).
9.2

Replacing inverter components

Fire or electric shock due to defective components
If an overcurrent protection device is triggered, the inverter may be defective. A defective
inverter can cause a fire or electric shock.
• Have the inverter and the overcurrent protection device checked by a specialist.
