Derating of the cable length due to temperature and clock frequency

INFORMATION

When using a CFX.. gateway, the temperature for calculating the derating must be assumed to be 5 K higher than expected in the control cabinet.
  • Example:
  • Expected control cabinet temperature: 45 °C
  • Temperature for calculating the derating: 45 °C + 5 K = 50 °C

The following tables show the values for the derating of the cable length due to the temperature and clock frequency:
