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the rating requirements for the input circuit breakers are superceded by the ratings listed in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.

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 National Electrical
code, 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 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.
