the BK terminal of the Motor connector (Aries drive).
2. Connect the second red/blue brake wire (Parker Motor cable or
equivalent) to the 24V return on your power supply.
3. Between the two red/blue wires, connect the fly-back diode. See
Figure 24.
4. Connect the +24 VDC power supply to the second BK terminal of the
Motor connector (Aries drive).
