* The circuit connected to terminal X1 – X7 are secondary circuits. (See [ 5. Appearance and name of each part ])
Insulation is needed against the primary side power supply (power supply of the motor brake).
Please do not connect them with the same power supply.
* For details, refer to 7-1 Power connector XA, XB, XC, XD and terminal block.
