ECO-mode
The UPS is equipped with the 'ECO-mode' feature. If the feature is enabled, the load is operated on utility
through the electronic bypass switch. If the utility is interrupted or out of limits the load is automatically
transferred to the inverter. Operating the load on utility improves the efficiency of the UPS with 5-8% and saves
on energy costs. We advise not to use the ECO-mode in case of an unstable utility.
After enabling the ECO-mode (please refer to service screens 5.3.3) the standard menu changes to:
LP 5-11U
LOAD 37%
ECO
NOTE: If LP-U units operate in parallel, the ECO-mode feature is not available.
5.5.6
Auto restart
If this feature is enabled and the unit has shut down (e.g. due to overload) the UPS will start up automatically
when the normal situation is restored. The off-factory setting is: enabled.
If the auto restart feature is disabled the unit will not automatically restart when the normal situation is restored
but the display will show:
AUTO RESTART OFF
PRESS ENTER
After 'Enter' the unit will restart. See also 5.3.3 'service screens'.

Superior Battery Management
-
Load dependent battery-end voltage: The allowable final battery voltage depends on the discharge
current: the higher the current, the lower the 'end-of-discharge' battery voltage. This gives maximum
capacity without over discharging. Over discharging results in failure to recover normal capacity and in
shortened battery life.
-
Equalize mode: When switched on for the first time the UPS will start boost-charging the batteries for 15
hours in order to equalize all battery voltages.
-
Boost mode: If after a discharge the battery voltage is lower than 240Vdc, the UPS will charge the
batteries with a boost charge voltage of 285Vdc. This enables fast recharging of the batteries. The
programmed battery charging mode will change from boost charge into float charge after boost charging
twice.
-
Temperature compensated battery charging: This feature reduces the battery charge voltage with
increasing temperature (-18mV/ C or -32.4mV/ F per 12V battery). As a result poor charging of the
batteries under low temperature conditions and overcharging of the batteries under high temperature
conditions are prevented.
