50 Hz).

Connecting an external battery

1. If you have received a battery box, use the supplied cable (Figure 6) to connect the battery box to
the battery port on the G-Net rear panel.
2. To avoid too short a backup time, verify that the battery voltage is appropriate for your G-Net
model:
•
The 1000 VA model requires a battery of at least 36 Vdc (3x12 V).
•
The 2000 VA model requires a battery of at least 72 Vdc (6x12 V).
•
The 3000 VA model requires a battery of at least 96 Vdc (8x12 V).
3. Connect one end of the battery cable to the battery port on the G-Net rear panel.
4. The other end of the battery cable has three branches.
•
Connect the red branch of the battery cable to the "plus" (+) terminal of the battery box.
•
Connect the black branch of the battery cable to the "minus" (–) terminal of the battery box.
•
Connect the yellow and green branch of the battery cable to the building's grounding sytem.
Important notice: The UPS is delivered with the batteries uncharged. The batteries are not able to
provide backup until they have been charged. To charge the UPS batteries: after connecting the battery
to the UPS, leave the UPS connected to the ac mains and with no load devices attached to the UPS, for
at least 8 hours.
It is permissible to use the UPS before the 8 hours of charging is complete. Just be aware that if you do,
the backup voltage (in the event of a power failure) will be shorter than normal until the battery charging
process has completed.
