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: 

 

 

 

 

NOTE: If LP-U units operate in parallel, the ECO-mode feature is not available. 

 

 

 

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: 

 

 

After ‘Enter’ the unit will restart. See also 5.3.3 ‘service screens’. 

 

 

 
- 

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.
