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the rating requirements for the input circuit breakers are superceded by the ratings listed in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

CAUTION
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.
