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
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.
