13.4.2 8200 vector 15 ... 90 kW
The brake resistor is connected to the frequency inverter 8200 vector 15... 90 kW
via the EMB9352-E brake chopper (accessories), which is connected to the DC
bus of the frequency inverter (terminals +UG, –UG). With low brake power the
EMB9351-E module (accessories) with integrated brake resistor can be used.
Brake choppers and brake modules can be connected in parallel.
