14. External overcurrent protection is not provided by this product, but is required by codes.
Refer to Table E through Table G for wiring requirements. If an output lockable disconnect
is required, it is to be supplied by the user.
15. Table K 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the rating requirements for the input circuit breakers are superceded by the ratings listed in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 L.

CAUTION
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 NEC, 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 Integrated Distribution Cabinet
(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.
