a forced ventilation system, then they can be operated with the cabinet doors closed. To
ensure an adequate air-inlet cross-section, the units are shipped without the standard
baseplates. In this case, the customer must ensure that no dirt, conductive dust, moisture or
small animals can enter the cabinets. Cables must not be routed in such a way that they
impede the flow of air through the cabinet floor opening. If the area beneath the drive units
can be accessed, then the customer must provide touch protection on the plant side.
