Powerware Powerware 9315 C A U T I O N, Table K. Maximum Input Circuit Breaker Ratings

INSTALLATION REFERENCE

14.External overcurrent protection is not provided by this product, but is required by codes. See Table E through Table G starting on page A-13for wiring requirements. If an output lockable disconnect is required, it is to be supplied by designated personnel.

15.Table K lists the maximum rating for continuous duty rated input circuit breakers.

C A U T I O N

To reduce the risk of fire, connect only to a circuit provided with maximum input circuit breaker current ratings from Table K according to the NEC, ANSI/NFPA 70.

16.Source protection for the AC input should be treated as if you were supplying a 750 kVA three-phase transformer, to allow for inrush current.

17.The input breaker (CB1) has a trip rating of 1200 amps AT and a standard ampere interrupting capacity (AIC) of 65,000 in symmetrical RMS amps. An optional 100,000 AIC breaker is available.

18.The input and bypass three-phase feeds should be symmetrical about ground, due to the existence of voltage surge protection devices.

19.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.

20.Output overcurrent protection and output disconnect switch are to be provided by the user. Table L lists the maximum rating for continuous duty rated output circuit breakers satisfying the criteria for both.
