Type A Configuration; Type B Configuration; Type A Dynamic Braking Resistor Installation; Type B Additional Dynamic Braking Unit And Resistor/Installation - LG SV-iS5 Instruction Manual

1.7.1

Type A Configuration

As standard on the iS5 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 iS5 series inverters that have a Type B
configuration power terminal strip.
