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.
WARNING
Nominal cables sizes below are based on the cable installation method B2 (ref: IEC60364-
NOTE
5-52:2001) unless otherwise specified, and are provided as a guide only. Ensure cables
used suit local wiring regulations.
The continuous output current ratings given below are for maximum 40 °C (104 °F), 1000 m altitude
and 3 kHz switching frequency. Derating is required for higher switching frequencies, ambient
temperature >40 °C (104 °F) and high altitude. For further information, refer to Chapter 5 Technical
data on page 76.
