Temperature resistance for the connecting cable
The temperature at the cable entries of the device is dependent on the measuring medium temperature T
medium
and the ambient
temperature T
amb.
.
For the electrical connection of the device, use only cables with sufficient temperature resistance in accordance with the following
table.

From an ambient temperature of T
amb.
≥ 60 °C (≥ 140 °F), the wires in the connection boxes with the enclosed silicone hoses need to
be additionally insulated.
Note
The signal cable supplied by ABB can be used without restrictions up to an ambient temperature of ≤ 80 °C (≤ 176 °F).
