Permissible cable temperature
Note
Permissible cable temperatures
At the max. ambient temperature of the S7-1500/ET 200MP system, you must select
sufficiently large wire cross-sections so that the permissible cable temperatures are not
exceeded.
Examples:
•
At an ambient temperature of 60° C, a current of, for example, 4 A per wire and a cross-
section of 1.5 mm² Cu, a connecting cable must be rated for a temperature range of at
least 90° C.
•
At an ambient temperature of 60° C, a current of, for example, 2 A per wire and a cross-
section of 1.5 mm² Cu, a connecting cable must be rated for a temperature range of at
least 80° C.
