Energy Saver mode allows the UPS to operate in Bypass mode. In this mode, the UPS is operating on bypass,
with the UPMs in standby, ready to automatically transfer to Normal mode if a commercial electrical power
brownout, blackout, overvoltage, undervoltage, or out-of-tolerance frequency condition occurs.
In High Alert mode the unit transfers from Energy Saver mode to Normal mode (inverter online) or if in Normal
mode remains in Normal mode for a default time period of one hour. The High Alert mode time period is
configurable by an Eaton Customer Service Engineer. High Alert mode allows the user to place the unit online
with full protection when outside conditions could cause a power disturbance. At the completion of the time
period, the unit defaults back to Energy Saver mode. If the High Alert command is received during the time
period, the timer will be restarted.
