■ Connection Example

Note: 1. If the detection power supply terminal (terminal 3) is not connected, failure detection is not performed and so be sure to connect this

terminal.

2. If the load is connected to terminal 1/L1, failure detection may not operate correctly and so connect the load to terminal 2/T1.

3. With inductive loads (relay coil, etc.), connect back-current prevention diodes to both sides of the load.
