9. 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). (See page 43.)
