The line-to-line unbalanced output capability of the UPS is limited only by the full load per phase current values
for AC output to critical load shown in Table 3-4 and Table 3-5. The recommended line-to-line load unbalance is
50% or less.
Bypass and output overcurrent protection and bypass and output disconnect switches are to be supplied by
the customer. Table 3-12 lists the recommended rating for output circuit breakers.

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, an external DC input overcurrent protection and disconnect switch is to be supplied by the
customer. Table 3-13 lists the maximum ratings for continuous-duty rated circuit breakers satisfying the criteria
for both. 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.
