Planning the electrical installation
What this chapter contains
This chapter contains the instructions that you must follow when selecting the motor,
the cables, the protections, the cable routing and the way of operation for the drive
system.
Note: The installation must always be designed and made according to applicable
local laws and regulations. ABB does not assume any liability whatsoever for any
installation which breaches the local laws and/or other regulations. Furthermore, if
the recommendations given by ABB are not followed, the drive may experience
problems that the warranty does not cover.
Motor selection and compatibility
1. Select the motor according to the rating tables in chapter
DriveSize PC tool if the default load cycles are not applicable.
2. Check that the motor ratings lie within the allowed ranges of the drive control
program:
•motor nominal voltage is 1/2 to 2 · U
•motor nominal current is 1/6 to 2 · I
3. Check that the motor voltage rating meets the application requirements:
