Remote ON/OFF circuit
Notes
When connecting a device such as a relay that generates counter electromotive force to the signal
output circuit, connect diodes that prevent counter electromotive force to both ends of the relay.
Explanation
When power is restored after the unit stopped automatically during a power failure, the unit
automatically restarts and supplies power. If you do not want to start the connected devices, turn
OFF their switches or set the auto startup setting after recovery from power failure (setting switch
2) to ON(Auto startup is not performed). (See page 43.)
