Terminal Connections
Note When the ALARM output turns ON, remove the cause of the high current and then shut off the external
power supply for approx. 1 second. After confirming that the cause has been removed, turn ON the power
supply again to reset the output. As shown in the diagram, it is recommended that a relay or switch that turns
ON or OFF only the external power supply be connected right before the B9 (+V). Check that this relay or
switch has a contact capacity higher than the external power supply current consumption (35 mA + load
current min.).
