6-1-8 Precautions and notes for the use of the Contact
Signal
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).
