NOTICE
Damage to the braking resistor
Incorrect setting for the duty cycle/voltage could damage the attached braking resistor. Use
the control knob to select the rated duty cycle of the braking resistor.

Note
Mounting dynamic braking modules side
-by-side causes
derating of power and current to the
mo
dules. 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)".
