CAUTION
To reduce the risk of a fire, connect only to a circuit that is provided with
maximum input circuit breaker current ratings from Table
10
in accordance
with the national and local installation rules.
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
10
.
The recommended line-to-line load unbalance is 50% or less.
