UL STANDARDS ON CABLING
To obey the UL (Underwriters Laboratories) regulations, use a UL-approved Class 1 copper wire with a minimum heat resistance of +140 or +167 °F.
You can use the drive on a circuit that gives a maximum of 100 000 rms symmetrical amperes, and a maximum of 600 V AC, 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.
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 the NEC and CEC.
For the correction factors for each temperature, see the instructions of the NEC and CEC.

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.
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.
NOTE!
The VACON® 100 FLOW and HVAC software do not have the dynamic braking or the brake resistor functions.
