To reduce the risk of fire, connect only to a circuit provided with maximum input circuit breaker current ratings
from Table 19 in accordance with NEC ANSI/NFPA 70.
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 5, Table 6, Table 7or Table 8. 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 provided by
the customer. Module Output Breakers (MOBs) are to be provided by the customer. Table 20 lists the
recommended rating for bypass, output, and MOB circuit breakers. Bypass breakers are not required for IOM
configurations.
