C.2. External Regenerative Resistors
Regenerative resistors can be externally mounted onto all XtraDrive models.
Mount a regenerative resistor externally if regenerative energy exceeds the
capacity of the XtraDrive.
If a regenerative resistor is to be mounted externally, the jumper between B2
and B3 terminals of XtraDrive must be removed.
