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).

Configuration
In general, no settings need to be made on the device. However, via the "Hot Connection Group"
functionality, the module can be configured with a fixed address, the so-called "Second Address". This
is carried out via the DIP switches of the module. The DIP switch settings are read after a "Power On"
of the module.
