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).

CAUTION!
and is NOT isolated from the mains.
3. 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.
4. Lead the DC cable through the slot in the cover
(bottom-left) and re-install the cover. Fasten it with 5
screws.
5. Use the clamps that came with the unit to attach the
DC cable to the rear of the cabinet. Position the clamp
in the slots (16).
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 2 battery fuses 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
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.
Proceed with 4.5.3 or 5.2.
