4. POWER CABLING
4.3.1 CABLE AND FUSE SIZES
We recommend the fuse type gG/gL (IEC 60269-1). To make a selection of the fuse voltage rating, refer to the mains. Do not
use larger fuses than what is recommended Table 16.
Make sure that the operation time of the fuse is less than 0.4 seconds. The operation time agrees with the fuse type and the
impedance of the supply circuit. For more information on faster fuses, speak to the manufacturer. The manufacturer can also
recommend some aR (UL recognised, IEC 60269-4) and gS (IEC 60269-4) fuse ranges.
The table also shows the typical sizes and types of cables that can be used with the AC drive. In the selection of cables, refer to
local regulations, cable installation conditions and cable specification.
