Chapter 1 – Installation1.7.1 Type A ConfigurationAs standard on the iS5 inverter, this type of configuration has internal dynamic braking resistor of 3% ED. When anapplication requires more braking duty, an external dynamic braking resistor may be connected instead of the internalresistor.R S T G N B1 B2 U V W3 PhasePower InputMotorDynamic Braking ResistorFigure 1 – Type A Dynamic Braking Resistor Installation1.7.2 Type B ConfigurationA Dynamic Braking Resistor or a Dynamic Braking Unit may be added to iS5 series inverters that have a Type Bconfiguration power terminal strip.R S T G P N B1 B2 U V W3 PhasePower InputMotorDynamic Braking ResistorFigure 2 – Type B Dynamic Braking Resistor InstallationR S T G P N B1 B2 U V W3 PhasePower InputMotorDynamicBraking UnitDynamic Braking ResistorFigure 3 – Type B Additional Dynamic Braking Unit and Resistor Installation15
