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 ‘Set-up Menu’. Dependent of the charge condition of the new batteries the new run time calculations may temporarily be unreliable.

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.

7.2Plug-in Cards

An option slot (rear panel, 13) allows easy installation of a relay or SNMP plug-in card. See sections 6.3 and 6.4 for more information.

7.3RPA-Facility (Redundant Parallel Architecture)

Nowadays there are many mission-critical applications that need a fault tolerant, 100 % reliable availability of mains power. By adding the RPA-facility to the UPS (rear panel, 14), highest standards for reliability can be met. The RPA-facility allows to connect 2, 3 or 4 units in parallel.

Connecting GE Digital Energy™ LP-U units in parallel is attractive for several reasons.

Redundancy: To achieve the highest possible level of power protection in a fault-tolerant network.

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.
