● 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 recovers after automatic stop of UPS at a power failure, the UPS automatically
restarts and supplies power. If you do not want to start the connected devices, turn off their
switch in advance.
