NOTICE
7.5.1.1 Maximum number of cables per phase
The maximum number of cables that can be used per phase depends on the type of the drive
and its nominal voltage.
Table 7-1: Maximum number of cables per phase
7.5.1.2 Determining the cable length
1. Determine the required length of a cable between the point of entry and the connection
point inside the cabinet.
2. Cut the cable to the required length before connection.
See layout drawing in “Appendix C – Mechanical drawings” for information on:
- Project-specific cable entry
- Distance between point of cable entry and terminals
- Busbar and fastening hole dimensions
- Busbar designations
See “Appendix D – Wiring diagrams” for information on:
- Conventions for cross-reference and device identification
Risk of damage or malfunction!
- Waste inside the cabinet can cause damage or malfunction.
- If possible, do not cut cables inside the terminal compartment.
- Retrieve any waste which accidentally dropped into the cabinet.
