* = If you use a multi-conductor cable, 1 of the conductors of the brake resistor cable stays
unconnected. It is also possible to use a single cable if you obey the minimum cross-
sectional area of the cable.
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.
•
The maximum temperature of the cable surface is +70 °C.
•
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 cross-
sectional area and the maximum number of cables.
For important information on the requirements of the grounding conductor, see chapter 2.4
Grounding and earth fault protection.
For the correction factors for each temperature, see the standard IEC60364-5-52.
5.3.2
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 in Table 18 and Table 19.
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.
