Note 1 The rating of the CR is 30V DC and 100mA or less.
Note 2 Connect a joint such as a contactor on L1/L2 on the terminal if an external cutoff is
required on the motor driving source in order to be complied with the safety category.
Note 3 In case nothing is connected to SIO connector, make short-circuit between S1 and S2
with a relay inside the controller.
