Digital Energy™ LP Series
7 - Optional Features
7.1Extended Runtime
Extended runtime versions are equipped with additional separate battery packs to increase the runtime of the unit. Additional batteries will increase the recharging time for the unit. All other operational information is the same.
If a battery pack is connected, the UPS must be informed about the new total battery capacity to allow a reliable recalculation of the available run time. Please refer to section 5.3.4
Connecting an external charger may cause damage to the UPS. As the batteries are not galvanically separated from the utility input, the external charger must be galvanically separated from the utility. Using an external charger will cause a false run time prediction during charging time, the correct run time will be shown 10 hours after reaching battery float charge. If you are in doubt, contact your dealer.
Battery pack A: 240V / 7 Ah
Battery pack B: 240V / 14 Ah

Connecting GE Digital Energy™
Redundancy: To achieve the highest possible level of power protection in a
By connecting units in parallel, using the N+x system, a redundant system can be created. In this case all the UPSs equally share the load in the system during normal operation. In this way every possible single point of failure will be eliminated. This means that if one of the UPSs in the parallel system fails, the other(s) can still supply the load guaranteeing full protection without any interruption.
Scalability: To add power if needed without investments beforehand.
Another reason for paralleling units is upgrading the power rating of the system. If e.g. a LP 5kVA is installed, the power rating can be upgraded to 10kVA by adding another LP 5kVA in parallel. This spread investment makes sure that you don’t have to invest in advance, but only when you need to.
GE’s unique RPA system has the following major advantages:
•RPA offers true redundancy because not only the power electronics are redundant, but also the batteries, the bypass circuit and the control logic,
•The RPA system is an option: you don’t have to buy it if you don’t need it.
