NetPro 2000-4000: user manual 4.0 (GB)
GE Digital Energy
g
Apart from the options described in 4.2 and 4.3 the following options are possible:
5.1
Extended Runtime (NetPro 2000/3000)
Extended runtime can be obtained by connecting a separate battery extension pack to the UPS. In this
case the UPS must be informed about the new total battery capacity to allow a reliable recalculation of the
available runtime (see section 3.4.3). Dependent of the charge condition of the new batteries the new
runtime calculations may temporarily be unreliable.
The additional batteries increase the runtime and recharging time for the unit, all other operational
information is the same as for standard models. It is not allowed to connect an external charger to the
UPS!
5.2
Isolation Transformer (NetPro 2000/3000)
Units equipped with a temperature protected isolation transformer ("") are housed in a larger
cabinet than the standard unit. The isolation transformer allows the output neutral to be connected to
-
protective earth (default setting)
-
the input neutral
or be isolated. Please contact your dealer.
5.3
PowerFLAG SerVICe Box for Modem Connection
If you connect the PowerFLAG SerVICe Box between the communication port of the UPS and a modem,
a programmed number can be dialed in case of a UPS alarm. It also allows service personnel to dial in
and check the status of the UPS to perform remote diagnostics. This way service costs, specially in
remote areas, can be reduced considerably.
6.1
General
The UPS is virtually maintenance free: take care of proper environmental conditions and keep air
inlets/outlets free of dust. Please read 2.1.
6.2
Batteries
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the
number of discharge cycles.
As a healthy battery is critical to the performance of the UPS, an automatic quick battery test is performed
regularly to ensure failsafe operation (see section 3.6.4). When the condition of the battery is critical, a
'replace battery'
alarm will be activated (see 3.4.2.2). Have your dealer replace the batteries as soon as
possible.
NOTE: under certain circumstances a
manual
battery test can result in a false alarm: please see 3.6.4
'quick battery test'.
Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. Sections
3.4.3 'battery capacity' and 3.6.5 give more information.
