Checklist for electrical installation
Use the following checklist to guide you through the electrical installation procedure for the
cabinet unit. Read the "Safety instructions" section at the start of these Operating
Instructions before you start working on the device.
Note
Check the boxes accordingly in the right-hand column if the activity applies to the cabinet
unit in your scope of supply. In the same way, check the boxes once you have finished the
installation procedure to confirm that the activities are complete.

Power connections
1
The electrical connections of the two sub-cabinets must be established for transport
units that have been shipped separately (refer to "Electrical installation / Power
connections / Electrical connection of units connected in parallel").
2
The line-side and motor-side power cables must be dimensioned and routed in
accordance with the ambient and routing conditions. The maximum permissible
cable lengths between the converter and motor must be observed depending on the
type of cable used (see "Electrical installation / Power connections / Connection
cross-sections and cable lengths").
The correct and uniform phase sequence must be observed in both sub-cabinets
when connecting cabinet units in parallel.
The PE ground at the motor must be fed back directly to the cabinet unit.
The cables must be properly connected with a torque of 50 Nm to the cabinet unit
terminals. The cables for the motor and low-voltage switchgear must also be
connected with the required torques.
3
For units connected in parallel, the connecting cables (-W001, -W002) for the DC
links on the two sub-cabinets must be closed (see "Electrical installation / Power
connections / Connection of DC link connectors").
4
The cables between the low-voltage switchgear and the cabinet unit must be
protected with line fuses to provide adequate conductor protection (DIN VDE 100,
Part 430 and/or IEC 60364-4-43) With version C, combined fuses must be used for
conductor and semi-conductor protection (EN 60269-4). See "Technical data" for the
appropriate fuses.
5
For strain relief, the cables must be clamped on the cable propping bar (C-type
mounting bar).
6
When EMC-shielded cables are used, screwed glands that connect the shield to
ground with the greatest possible surface area must be provided on the motor
terminal box. On the cabinet, the cables must be grounded with the clips supplied
with the EMC shield bus with the greatest possible surface area (shield bus supplied
with option L00 or can be ordered separately with option M70 – see "Electrical
installation / EMC-compliant installation").
