6.6 Ground cable connection andcable shield connections
Cable shields and cable armor are connected to the FE (Functional
Earth) busbar inside the drive. The ground cable is connected to the PE
(Protective Earth) busbar of the drive.
To identify the ground busbar, see the
applicable mechanical drawings.

Cabling between drive and integrated transformer includes the
following connections:
• Transformer primary and secondary cables
• Temperature sensor cables
• Three-phase power supply cable and control
cable to each of the transformer fan units
• Air filter and pressure monitoring cable
• Heating cable (option)
The cables are identified by their specific number
and are labeled with the designation of the termi nal where they are connected to.
The terminals for the primary (6-3: 4) and the sec ondary cables (6-3: 5) are located on the side wall
of the transformer cabinet. The terminals are
accessible through cutouts in the terminal com partment of the drive. The power supply and con trol cables of the transformer’s fan units are
routed through the cable lead-through (6-3: 3) on
the side wall.
For further information, see the applica ble wiring diagrams.
