DC-bus with r
egenerave power supply module
If regenerave energy is to be fed back into the AC system from a DC-bus connecon, a
regenerave power supply module can be used.
The DC power supply adapter E70AZEVE001 is required to connect the DC cable from the DC
output of the regenerave power supply module to the DC busbar system of i750.
A brake resistor can addionally be connected to the brake chopper of the regenerave power
supply module.
