Change the connection marked with
1) Auxiliary control power input terminals (R0, T0)
Be sure to connect these terminals to the main power supply
contacts
of the magnetic contactor (73 or MC) for the power supply circuit.
2) Auxiliary main circuit power input terminals (R1, T1),
with R1 and T1
Be sure to connect these terminals to the main power supply
