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 the 500 V drive.
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 in the tables in
10.3.1 List of Cable and Fuse Size Information
. In the
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.
•
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 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

10.3.1 List of Cable and Fuse Size Information
. In the
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 Underwriters Laboratories UL 61800-5-1.
•
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.
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 the Underwriters Laboratories standard UL 61800-5-1.
