Connection diagrams
With regenerative power supplies, the energy released while braking is returned to
mains. If while returning it, due to the application, the energy saved in the
capacitors may generate a higher voltage than the maximum bus voltage allowed,
a Crowbar resistor must be installed to dissipate that excess of energy.
