To reduce the risk of fire, connect only to a circuit provided with maximum input circuit breaker current ratings from Table K in accordance with the National Electrical code, ANSI/NFPA 70.

16.Source protection for the AC input to bypass should be treated as if supplying a 160 kVA three-phase transformer, to allow for inrush current if an IDC with a transformer is installed. Bypass input wiring and bypass input breaker rating should be treated as if supplying a 160 kVA load, regardless of the rating of the UPS.

17.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 E through Table G. The recommended line-to-line load unbalance is 50% or less.

18.Bypass and output overcurrent protection and bypass and output disconnect switches are to be provided by the user. Table L lists the maximum rating for bypass and output circuit breakers satisfying the criteria for both.
