4. POWER CABLING
Table 16: The cable and fuse sizes for N800A
The dimensions of the cables must agree with the requirements of the standard IEC60364-5-52.
• The cables must be PVC-isolated.
• The maximum ambient temperature is +30 °C (86 °F).
• The maximum temperature of the cable surface is +70 °C (158 °F).
• Use only cables with a concentric copper shield.
• The maximum number of parallel cables is 9.
When you use parallel cables, make sure that you obey the requirements of the crosssectional area and the maximum number
of cables.
For important information on the requirements of the earth conductor, see chapter 1.4 Earthing and earth fault protection.
For the correction factors for each temperature, see the standard IEC60364-5-52.
4.3.2 CABLE AND FUSE SIZES, NORTH AMERICA
We recommend the fuse class T (UL & CSA). To make a selection of the fuse voltage rating, refer to the mains. Refer also to
local regulations, cable installation conditions and cable specification. Do not use larger fuses than what is recommended
Table 17.
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 high speed Class J (UL & CSA ) and aR (UL recognised) fuse ranges.
The solid state short circuit protection does not supply protection for the branch circuit of the AC drive. To supply the branch
circuit protection, refer to the National Electric Code and the local regulations. Do not use other devices than fuses to supply
branch circuit protection.
