Note
Use 75 °C wire for an ambient temperature of 40 °C or less and use 90 °C wire for ambient
temperature between 40 °C and 60 °C.
A correction factor of K = 0.71 has been used based on the following:
A maximum of four cables are laid side by side on a cable ladder.
The ambient temperature during cable operation is 30 °C.

NOTICE
To ensure that input/output precision is ≤ 1 %, it's recommended that the cable length be
less than (<) 5 m. If you don't have this precision requirement, use a cable which is less than
(<) 30 m.
