Configuration instructions
DC link capacitance
When configuring the drive line-up, please note that only one Braking Module Booksize
Compact may be used per complete 500 µF DC link capacitance.

DC link cable
In a multi-row or distributed drive line-up, the DC links are connected to each other via a DC
link cable. When using a Braking Module Booksize Compact in the drive line-up, this cable
must not be longer than 10 m. In all cases, the DC link cable must have low impedance and
a cross-section of at least 10 mm

.
Parallel operation
During configuration of parallel operation for Braking Modules Booksize Compact,
dimensioning can only take 90% of the specified braking power into account. Only the peak
powers may be added without derating.
The following applies when connecting Braking Modules in parallel:
