Disabling 8 A current limitation
Select the checkbox Disable current limitation (8 A) .
If current limitation is enabled (checkbox deselected), then the UPS uses battery operation to
check whether the UPS battery is discharged with 8 A for longer than 16 seconds. If so, then an
overcurrent alarm is sent to the PC.
Enabling one of the two following options determines how the UPS should perform when an
overcurrent alarm occurs:
If Turn-off within 1 minute is selected, then the UPS will turn-off within one when an overcurrent
alarm occurs.
If Perform "low battery" shutdown is selected, then the UPS will also signal a "Low battery
alarm" in addition to the overcurrent alarm and will turn off after the defined Low battery
shutdown time . This will allow the operating system to shut down properly when UPS service
is enabled.
Information:
• UPS settings can only be changed using UPS firmware version 1.10 and
higher. If there are no changed settings on the UPS, then the factory or default
settings are used.
• The UPS is automatically restarted after UPS settings have been changed.
This can cause a brief disruption in communication with the UPS.
• Administrator rights are required in order to change the energy options or
display the UPS status.
Information:
It is not UL compliant to switch off the 8 A current limitation on devices during
battery operation!
"Low Battery" shutdown caused by an over-current of > 8 A on devices during
battery operation is not UL compliant!
Information:
Current limitation is only supported with UPS firmware version 1.10 and higher.
Warning!
The operating system will not be properly shut down if an overcurrent alarm occurs!
