Input Power Cables and Fuses
Branch circuit protection must be provided by the end-user, sized per national and
local electric codes. Recommendations for fuses for short-circuit protection on the
mains cable are below.

Note 1: Mains cable sizing is based on a correction factor of 0.71 (maximum of 4 cables laid on a cable
ladder side by side, ambient temperature 30 °C (86 °F), EN 60204-1 and IEC 364-5-523). For other
conditions, dimension the cables according to local safety regulations, appropriate input voltage and
the load current of the drive. In any case, the cable must be between the minimum limit defined in this
table and the maximum limit defined by the terminal size (see
Note 2: Fuse Type: IEC 269 gG, UL Class T.
Note 3: Fuses from other manufacturers can be used, if they meet the ratings.
