4.5.5 Installation of GE Digital Energy™ LP-U battery extension pack(s)
The numbers between (brackets) refer to figures 19-21 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. Be sure 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 DC fuse holders at the rear of the battery
pack (16) and make sure that the fuses have been
removed.
1a. Open the DC fuse holders at the rear of the UPS (16)
and make sure that the fuses have been removed.
2. UPS rear panel: loosen the screws, and remove the
cover plate (11) and conduit box (17).
CAUTION!
and is NOT isolated from the utility.
3. Break out the indicated part of the conduit box, fix the
gland of the DC cable in this opening.
4. Connect the DC connector of the battery pack (15a)
to the DC socket of the UPS (15). Be sure that the
colours match. You will hear a click when the cable is
properly installed.
5. Re-install the cover plate and conduit box.
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 parallel.
NOTE: A maximum of two Digital Energy™ 14Ah
battery cabinets can be connected without additional
fusing. Every two additional Digital Energy™ 14Ah
battery cabinets must be connected over a 60Amp
fuse, rated for 300Vdc.
NOTE: Third party battery cabinets must be
connected over a 60Amp fuse, rated for 300Vdc,
using the Digital Energy™ external battery cable
(order separately).
7. Insert the 2 (7Ah) or 4 (14Ah) DC fuses of the (each)
battery pack, insert the DC fuses of the UPS and
close the fuse holder(s) of battery pack and UPS (16).
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 a circuit breaker) 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.
Proceed with 4.5.1 or 5.2.
