Auto restart: Allows the automatic restart of the UPS when input power is restored after a complete shutdown of the UPS
system.
•
Enable (default) — The UPS will restart automatically when the input power is restored after a complete shut
down.
•
Disable — The UPS will not restart automatically.
Auto restart delay: Length of time to elapse before an automatic restart after input power is restored.
•
0 - 999 seconds (default 0 seconds)
Guaranteed shutdown: Forces a continued shutdown of the UPS once the Low Battery threshold is reached, even if input
power is restored during this time. This can be used to make sure that connected equipment shuts down completely. When
using the low battery relay output to gracefully shut down connected equipment, it is possible that the input power is restored
after the Low battery output is triggered. In this situation, the connected equipment could power down smoothly but never
lose input power, causing it not to start back up as intended. Enabling this option prevents this situation from occurring by
ensuring a shutdown of the output.

Enable

Disable (default)
Start with no battery: Allows the UPS to start when the battery has reached the end of discharge (EOD). This can be used to
turn on the UPS and power the attached load without battery protection when utility power has been restored after the
battery was fully depleted. It works in conjunction with the Auto restart setting above.
•
Enable (with Auto restart enable) — The UPS will power the load with no user intervention when mains power
returns after the battery has been fully depleted.
•
Enable (with Auto restart disabled) — The UPS will start up and allow the user to turn on the output when power
returns after the battery has been fully depleted.
•
Disable (default) — The UPS cannot start with a fully depleted battery.
Remote control: Allows the UPS to be controlled remotely via the CLI or RDU101 card.
•
Enable
•
Disable (default)
