2.5 Non-prescribed use
“Prescribed use” means, that the servo drive system is used according to the environmental
conditions described in this documentation.
•
It must not be used in electrical equipment on ships (service afloat) or in offshore
applications because of the conductive pollution.
•
It must not be used in environmental conditions that do not meet the conditions
described in this documentation (too hot, without closed switchgear cabinet,
wrong mounting position, etc.)
Be very careful in plants, were conductive material (carbon fiber, graphite with machining of
graphite cast iron or similar) is easily purgeable in the factory floor. In this case, the switch-
gear cabinet has to be sealed very carefully (no forced ventilation with blower filter) or be
placed outside the factory floor. Especially during start-up of the machine, the risk is high
because of open switchgear cabinet doors. Servo drives, which become contaminated,
cannot be used anymore.
