Ul Standards On Cabling; Cable Selection And Dimensioning; Cable Selection And Dimensioning, North America - Danfoss Vacon NXP Series Operating Manual

Operating guide | VACON® NXS/NXP Air-cooled
These instructions are valid only for processes that have 1 motor and 1 cable connection from the AC drive to the motor. In other
conditions, speak to the manufacturer to get more information.

6.1.2 UL Standards on Cabling

To comply with the UL (Underwriters Laboratories) regulations, use a UL-approved copper wire with a minimum heat resistance of
60 °C or 75 °C (140 °F or 167 °F). To comply with the standards, use cables with +90 °C (194 °F) heat resistance for sizes 0170 2 and
0168 5 (FR8), and 0261 2, 0261 5, 0300 2 and 0300 5 (FR9).
Use Class 1 wire only.
When the drive has Class T and J fuses, it can be used on a circuit that gives a maximum of 100 000 rms symmetrical amperes, and a
maximum of 600 V.
The integral solid-state short-circuit protection does not give a branch circuit protection. Obey the National Electric Code and any
additional local codes to get the branch circuit protection. Only fuses give the branch circuit protection.

6.1.3 Cable Selection and Dimensioning

Find the typical sizes and types of cables used with the AC drive the tables in
selection of cables, refer to local regulations, cable installation conditions and cable specification.
The dimensions of the cables must comply 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 using parallel cables, make sure to 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
For the correction factors for each temperature, see the standard IEC60364-5-52.

6.1.4 Cable Selection and Dimensioning, North America

Find the typical sizes and types of cables used with the AC drive the tables in
selection of cables, refer to local regulations, cable installation conditions and cable specification.
The dimensions of the cables must comply with the requirements of the National Electric Code (NEC) and the Canadian Electric
Code (CEC).
• The cables must be PVC-isolated.
• The maximum ambient temperature is +86 °F.
• The maximum temperature of the cable surface is +158 °F.
• Use only cables with a concentric copper shield.
• The maximum number of parallel cables is 9.
