Closed Cabinet Door (Air Inlet From Below Through Floor Opening) - Siemens SINAMICS S120 Operating Instructions Manual

2.6.26

Closed cabinet door (air inlet from below through floor opening)

The cabinet is equipped with doors without integrated ventilation meshes.
Note
Floor panel
To ensure an adequate air-inlet cross-section, the units are shipped without the standard floor
panels.
Defective grounding straps
Doors that are not grounded can be at a hazardous voltage. This can result in severe injury
or death.
It is not permissible that grounding straps, which are attached to the doors, are damaged
when disassembling. When assembling, correctly and carefully connect the grounding straps
to the doors.
High voltage
The converter has no floor panels. When touched, high voltages in the converter can result
in severe injury or death.
If it is possible to enter the area underneath the cabinet, it is essential that plant-side shock
protection is provided for this area.
Dirt and moisture
Dirt, conductive dust or moisture can result in material damage and as a consequence to
converter failure.
In this case, you must ensure that no dirt/conductive dust or moisture can enter the cabinet.
Cables must not be routed in such a way that they impede the flow of air through the cabinet
floor opening.
Non compliance with environmental conditions
Overheating, drawing in dirt and pollution and the ingress of moisture can result in material
damage and as a consequence to converter failure.
Comply with the required environmental conditions to prevent, for example, overheating,
drawing in dirt and pollution and the ingress of moisture into the cabinet.
