CAutIoN
• Be sure to check the contact capacity of the relay contact. If the capacity is insufficient, use multiple contacts
as needed. (*1 in the diagram)
• Connect a load with a current of 300 mA or less to the emergency stop wiring using ES1 and ES2. If a load with a
current of more than 300 mA is connected or if a current of more than 300 mA flows without connecting any
load, the controller may malfunction. (*2 in the diagram.)
