There is no manual DC disconnect device within the UPS.
Battery voltage is computed at 2 volts per cell as defined by Article 480 of the NEC. Rated battery current is
computed based on 2 volts per cell.
If required, external DC input overcurrent protection and disconnect switch is to be supplied by the customer.
Table 11 and Table 12 list the recommended ratings for circuit breakers satisfying the criteria for each battery
voltage. Recommended disconnect size is based on a maximum full load discharge time less than 3 hours. For
longer discharge times a larger disconnect may be required.
