11.5.4 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.
Category 2/3G
For cables suitable only for temperatures up to T= 80 °C (T = 176 °F),
the interconnection of both circuits needs to be taken into account in
the event of a fault. Otherwise, the restricted temperature ranges
listed in the following table shall apply.
Category 2D
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.
