Permissible cable temperature
Note
Permissible cable temperature
When choosing a cable, remember that the cable temperature in operation can be up to
30 °C higher than the ambient temperature of the S7-1500/ET 200MP system.
Example: If you use the system in a switchgear cabinet at an ambient temperature of 30 °C,
you must use a connecting conductor with a temperature range of at least 60 °C.
With terminals that carry a current load of ≥ 8 A during operation, you must expect a cable
temperature of up to 65 °C above the ambient temperature.
You can determine the required cable temperature more precisely for each application. To do
so, measure the cable temperature in the system at a load corresponding to the maximum
possible power and ambient temperature values.
You should specify other connection types and material requirements based on the electrical
characteristics of the circuits you use and the installation environment.
