5. Operation
5.4 Setting High Efciency mode
In High Efciency mode, the UPS operates normally on Bypass and transfers to Online (or Battery) mode
in less than 10 ms when utility fails. Transfers to High Efciency mode will be active after 5 minutes
of Bypass voltage monitoring: if Bypass quality is not in tolerance, then the UPS will remain in Online
mode.
Eaton recommends to use the HE mode only to protect I/T equipment.
To set the High Efciency mode:
1. Put the UPS on Bypass: press any button to activate the menu options, select Control and Go to
Bypass.
2. Then press Escape and select Settings, In/Out settings, and High Efciency mode.
3. Select Enabled and Enter to conrm.
4. The UPS transfers to High Efciency mode in 5 minutes.
5.5 Conguring Bypass settings
The following settings are available for conguring 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 conrm.
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 dene 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 Conguring battery settings
Automatic battery test
Automatic battery tests are done every week in constant charging mode and at each cycle in ABM mode.

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 modied.
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.
