Installation Information
12.
External overcurrent protection is not provided by this product, but is required by codes.
Refer to Table E or Table F for wiring requirements. If an output lockable disconnect is
required, it is to be supplied by user.
13.
Table J 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the rating requirements for the input circuit breakers are superceded by the ratings listed in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 K.
Table J. Maximum Input Circuit Breaker Ratings
CAUTION: To reduce the risk of fire, connect only to a circuit provided with
maximum input circuit breaker current ratings from Table J in accordance with the
National Electrical code, ANSI/NFPA 70.
14.
Source protection for the AC input should be treated as if you were supplying a 40 kVA or
80 kVA three phase transformer, to allow for inrush current.
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 or Table F. The
recommended line-to-line load unbalance is 50% or less.
16.
Bypass and output overcurrent protection and bypass and output disconnect switches are
to be provided by the user. Table K lists the maximum rating for bypass and output circuit
breakers satisfying the criteria for both.
