● Automatic detection of braking resistors without thermostatic switch and corresponding
braking power monitoring (only if the "Braking resistor without thermostatic switch" setting
is used)
● I

t monitoring of the Braking Module
● Temperature monitoring of the Braking Module
● Temperature monitoring of the connected braking resistor with thermostatic switch (only
for setting "Braking resistor with thermostatic switch")
● Short-circuit and overload detection (for all braking resistors)
● Ground fault detection (for all braking resistors)
Several Braking Modules Booksize Compact can be connected in parallel to increase the
braking power. In this case, the braking energy is divided between the modules. Formulas
for calculating the parallel connection are given in Chapter Notes on configuration
(Page 516).
A parallel connection of the Braking Module Booksize Compact to SINAMICS S120 Basic
Line Modules 20 kW and 40 kW is also possible.
Safety instructions for Braking Modules Booksize Compact
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 27) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire hazard due to overheating because of inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel due to
smoke and fire. This can also result in increased failure rates and a shorter service life of
the components.
• Maintain the 80 mm clearances above and below the components.
