9. Precautions and notes on the use of the Contact Signal
● When connecting a device that generates counter electromotive force to the signal output circuit
such as a relay, connect diodes to prevent counter electromotive force at the both end of the
relay.
● 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 restart setting (setting switch 2) to ON. (See page 32.)
