22. Table N lists the battery shunt trip trip wiring requirements.
Table N. Battery Shunt Trip Wiring Requirements
Description ST
CB2TB Points 9, 10
Output Max Pulse 220 VA instantaneous
Wiring #18 AWG minimum
23. There is no DC disconnect device within the UPS.
24. The DC input to the UPS is protected by internal fuses F30 and F31.
25. Recommended wire size is #18–14 AWG.
26. Battery voltage is computed at 2 volts per cell as defined by Article 480 of the
NEC. Rated battery current is computed at 2 volts per cell.
27. The battery wiring used between the battery and the UPS should not allow a
voltage drop of more than 1% of nominal DC voltage at rated battery current.
