11.4.2 Medium temperatures / Temperature
classes
For the supply circuit "Terminals 31, 32" and the switching outputs
"Terminals 41, 42", cables suitable for temperatures up to T = 110 °C
(T = 230 °F) can be used without restriction.
For cables suitable only for temperatures up to T= 80 °C (T = 176 °F),
the restricted temperature ranges listed in the following table shall
apply.
