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-13 for 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.

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.
