I bought a used Square-D 8922 EMB 20/480 DC injection brake and I'm trying to wire it in to an old Okuma LS lathe with a 3 phase (240V) motor. It didn't come with instructions but I was able to find a manual however they don't define the terms used and it's unclear to me how to complete the wiring. The diagram from the manual is below as well as the wiring diagram for the Okuma lathe. I'm pretty sure the main power wiring is correct (L1,L2,T1,T2) shown in the diagram. I connected I5,I8 in series with the Start/Stop circuit however I'm not sure where 25,28 and X0,X0 are supposed to go. I originally thought X0 was a capacitor however it shows the same M1 symbol as show in series with 25,28 so I'm not sure what M1 is mean to represent.
