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!
The battery voltage is 240Vdc 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
GE Digital Energy
14Ah
battery cabinets can be connected without additional
fusing. Every two additional
GE 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
GE
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 4.4.1 or 5.2.
