Table 2-1 400 V drive ratings, cable sizes and fuse ratings
* These fuses are fast acting.
** These ratings are for 2 kHz switching frequency. For ratings at 3 kHz switching frequency refer to the Power and
current ratings in section 5.1.2

Table 2-2 Protective ground cable ratings
Fuses
The AC supply to the drive must be installed with suitable protection against overload and
short-circuits. The following section shows recommended fuse ratings. Failure to observe
this requirement will cause risk of fire.
Nominal cables sizes below are based on the cable installation method B2 (ref: IEC60364-
5-52:2001) unless otherwise specified, and are provided as a guide only. Ensure cables
used suit local wiring regulations.
