NOTICE Derating
Depending on the installation location of the module (SK 180E, SK 190E or SK 2xxE), the operating mode (S1,
S3 ...) and the installation type (wall-mounting, motor -mounting) of the frequency inverter as well as the type of
motor used (IE1 / IE2 / ...) restrictions to the permissible ambient temperature must be taken into account. If the
permissible ambient temperature is exceeded, the module may heat up to an impermissible extent and switch off
with an error message (E104.0).
Maximum ambient temperature *
Operating mode Installation type SK 180E / SK 190E SK 2xxE
S1 Motor 25°C 30°C
S3 ED 50 %, 10min Motor 40°C n. s.
S3 ED 70 %, 10min Motor n. s. 40°C
S1 Wall (unventilated) 37°C 42°C
S1 Wall (ventilated) 47°C 48°C
* The limits of the frequency inverter must not be exceeded (refer to the frequency inverter manual).
