Note
Mounting dynamic braking modules side-by-side causes derating of power and current to the
modules. To avoid this, Siemens recommends that you observe the clearance requirements
for V20 converters when mounting the dynamics braking modules. For more information, see
Section "Mounting orientation and clearance (Page 23)".
