5. Operation
5.4 Setting High Efficiency mode
On High Efficiency mode, the UPS operates normally on Bypass, transfers to Online (or Battery) mode in
less than 10 ms when utility fails, and transfers back to Bypass in 5 minutes after utility returns.
Eaton recommends to use the HE mode only to protect I/T equipment.
To set the High Efficiency mode:
1.
Press any button to activate the menu options, then select Settings, Output settings, and High
Efficiency mode.
2.
Select Enabled and Enter to confirm.
5.5 Configuring Bypass settings
The following settings are available for configuring Bypass operation.
Bypass transfer out of tolerance
1.
Press any button to activate the menu options, then select Settings, Output settings, and Bypass
transfer.
2.
Select Enabled or Disabled for BP AC NOK, and Enter to confirm.
If Enabled, the UPS transfers to Bypass even if Bypass AC source is out of tolerance, depending on
output mode. If Disabled, the UPS output is shutdown.
Interrupt time
This setting is displayed to define the break duration during transfer to Bypass, only if transfer out of
tolerance is enabled. 10 ms or 20 ms can be selected.
5.6 Configuring battery settings
Automatic battery test
Automatic battery tests are done every week in constant charging mode and at each cycle in ABM mode.
The tests frequency can be modified.
During the test, the UPS transfers to Battery mode and discharges the batteries for 25 seconds under load.
Battery mode is not displayed and battery low alarm does not activate during a battery test.
The battery test may be cancelled due to bad conditions, or failed.
Low battery warning
During discharge, the low battery alarm is activated if the battery capacity goes below 20%.
This threshold can be modified.
External battery setting
The number of Extended Battery Module is automatically detected, or can be set manually in number of
EBM or in Ah.
Deep discharge protection
This setting is recommended to avoid damaging the battery. Warranty is void if deep discharge protection is
disabled.
