7-4-7. Precautions and notes for the use of the Contact Signal
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 (“Settings”
- “Boot Settings” - “Auto reboot” on the LCD) to “disable”. (See page 32.)
A relay output type contact signal card is available for separate purchase.
It can be loaded into the option slot on the back of the UPS.
