Ballast connector
The Ballast connector located at the bottom of each compact drive allows
enabling the braking resistor (Ballast resistor) and accessing the power DC
BUS (L+, L-).
The following table shows the values for gap, tightening torque (wire entry
holes) and other data regarding the screw-on terminals and plug-in terminals
of the ballast connectors according to drive model:
