External overcurrent protection is not provided by this product, but is required by codes.Refer to Table E through Table H for wiring requirements. If an output lockable disconnectis required, it is to be supplied by the user.15. Table L lists the maximum rating for input circuit breakers. When wiring a single-feed input,the rating requirements for the input circuit breakers are superceded by the ratings listed inTable M.Table L.

Source protection for the AC input to bypass should be treated as if supplying an 80 kVAthree-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 an80 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 loadper phase current values for AC output to critical load shown in Table E through Table H.The recommended line-to-line load unbalance is 50% or less.
