Installation Information

12.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 disconnect is required, it is to be supplied by the user.

13.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 When wiring a single feed input, the rating requirements for the input circuit breakers are superceded by the ratings listed in Table M.

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

14.Source protection for the AC input to bypass should be treated as if supplying an 80 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 suppling an 80 kVA load, regardless of the rating of the UPS.

15.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 H. The recommended line-to-line load unbalance is 50% or less.
