4.5.2 LP 3/5/6-11: installation of GE Digital Energy™ LP battery extension pack(s)
The numbers between (brackets) refer to figures 12-13 in section 5.1.
Battery extension pack(s) are shipped with all materials
necessary to connect them to the UPS. The pack(s) can
be connected to the DC connector (15) at the rear panel of
the UPS. We recommend to switch off the UPS before
proceeding: be sure that the UPS can be switched off
without causing damage to the load, and turn all circuit
breakers (7-8-9) into ‘off’ position (down).

1. Open the fuse holders at the rear panel of the UPS
(17) and battery pack (18) and make sure that the
fuses have been removed.
2. UPS rear panel: loosen the 4 screws that hold the
cover of the DC connector (15), and open the cover.
The actual DC socket is fixed to the inner side of the
cover.
CAUTION!
The battery voltage is 240Vdc
and is NOT isolated from the mains.
3.
Break out a part of the cover: a large part (grey in fig.
7) if your battery extension pack is equipped with a
swivel (19, fig. 13a), otherwise a small part. If
applicable, mount the swivel in the cover.
4. Connect the DC connector of the battery pack (15a)
to the DC socket of the UPS (15). You will hear a click
when the cable is properly installed.
5. If applicable lead the DC cable through the hole on
the left side of the cover. Re-install the cover. Fasten
it with 4 screws.
6. In case of 14Ah battery packs: using the DC
connector of the battery pack (15) you can install a
second, third, etc. pack. 7Ah battery packs cannot be
connected in series.
7. Insert the battery fuse of the UPS (17). Insert the 2
(7Ah) or 4 (14Ah) fuses of the (each) battery pack
(18). Close the fuse holders (17, 18).
8.
In order to calculate the available back-up time related
to the actual load, information on the capacity of the
battery set is stored in the UPS. As the total battery
capacity changes when battery extension packs are
installed, the battery capacity must be re-
programmed. See 5.3.4.
In case of a custom-built battery extension set you may
want to install a ‘battery disconnected’ alarm device.
9. Be sure that the UPS is switched off, and
disassemble the RS232/Contact Interface Card (12)
from the unit.
If the card is disassembled during
normal operation the UPS will shut down!
Remove the wire from connector J3 (pin 1 and 2).
Install the wiring of a normally closed contact (e.g. an
auxiliary contact of an MCB) to pin 1 and 2. Re-install
the interface card. If the contact is opened, the UPS
will generate an ‘EXTERNAL BATTERY FUSE
FAILURE’. See 5.3.2 for more information.
