Danfoss VACON 100 INDUSTRIAL Installation Guide

UL STANDARDS ON CABLING
CABLE AND FUSE SIZES, NORTH AMERICA
To obey the UL (Underwriters Laboratories) regulations, use a UL-approved Class 1
copper wire with a minimum heat resistance of 60 or 75 °C (140 or 167 °F).
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.
You can use the drive on a circuit that gives a maximum of 100 000 rms symmetrical
amperes, and a maximum of 600 V, when the drive is protected by Class T and J fuses.
The dimensions of the cables must agree 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.
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 ) fuse ranges.
The solid state short circuit protection does not supply protection for the branch circuit
of the 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.
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 grounding conductor, see the
NEC and CEC.
For the correction factors for each temperature, see the instructions of the NEC and CEC.
