1.7.1 Type A Configuration
As standard on the ACtionMaster inverter, this type of configuration has internal dynamic braking resistor of 3% ED. When
an application requires more braking duty, an external dynamic braking resistor may be connected instead of the internal
resistor.

1.7.2 Type B Configuration
A Dynamic Braking Resistor or a Dynamic Braking Unit may be added to ACtionMaster series inverters that have a Type B
configuration power terminal strip. As standard, this type of configuration has in
