Auto restart
Allows the automatic restart of the UPS when input power is restored after a complete shutdown of the UPS
system�
• Enable = The UPS will restart automatically when the input power is restored after a complete shut
down� (default)
• 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)
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 that a shutdown of the output happens�
• Enable (default)
• Disable
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 = The UPS cannot start with a fully depleted battery (default)
