User Manual Smart-UPS RC UXI/UXICH 1000/2000/3000 VA 220/230/240 Vac Tower/Rack-Mount 4U 16
External batteries
APC battery solution
Refer to the APC Web site, www.apc.com or an APC dealer for information regarding the APC external
battery pack.
Third party battery solution
Batteries must be sealed lead-acid type. Use 50 A, 250 VDC fuses with an interrupt rating of > 20,000 A.
The UPS internal battery chargers are optimized only for VRLA/AGM type batteries. Do not exceed the
maximum recommended battery charging current rate when configuring the amp-hour capacity of the
external battery system.
The UPS is intended for use with 96 VDC nominal battery voltage. The external battery system connected
to the UPS must not exceed 96 VDC nominal voltage. This equals eight 12 V batteries connected in series.
Refer to the Configuration section in this manual for details on battery string configuration.
The internal battery chargers operate in a constant current/constant voltage charging mode.
• 1000 VA UXI/UXICH models with 250 W internal battery charger:
Typical charging current is 2.2 A.
• 2000/3000 VA UXI/UXICH models with 600 W internal battery charger:
Typical charging current is 5 A.
External batteries must be wired prior to connecting batteries to the UPS.
If using a non-APC battery pack, a 96 V battery string
must be wired to the UPS using the enclosed battery
cable.
Connect the UPS to a battery system
1. Connect the positive (red), ground (green), and negative (black), wires to the positive, ground, and
negative terminals on each external battery system.
2. Plug the cable connector into the battery connector receptacle on the rear side of the UPS.
3. Secure the cable connector with one screw.
