■Action
Before powering on or off the load power supply, check that the time taken to power on the load power supply itself is 10ms or
more. Then, install a switch (SW1) to the primary side of the load power supply.

When installing the switch to the secondary side, connect a capacitor and resistor, and increase the time taken to power on
the load power supply (10ms or more).
