1)
Type of connection of standard brake resistors from Table (chapter 2.6.1),
Here: "//" = connected in parallel, "-" = connected in series
2)
Connection example according to the following diagram
3)
Maximum possible peak braking power with the stated resistor combination
4)
Maximum possible pulse energy with 1% switch-on duration (1.2 sec once within 120 sec.) taking into account the absolute limit of the
frequency inverter
