13.
External overcurrent protection is not provided by this product, but is required by codes.
Refer to Tables A through G for wiring requirements. If an output lockable disconnect is
required, it is to be supplied by designated personnel.
14.
Table G lists the maximum rating for continuous duty rated input circuit breakers.
CAUTION: To reduce the risk of fire, connect only to a circuit provided with
maximum input circuit breaker current ratings from Table G in accordance with the
National Electrical code, ANSI/NFPA 70.
15.
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.
16.
The input breaker (CB1) has a trip rating of 1200 amps AT and a standard Amp
Interrupting Capability (AIC) of 65,000 in symmetrical RMS amps. An optional 100,000 AIC
breaker is available.
17.
The input and bypass three phase feeds should be symmetrical about ground, due to the
existence of voltage surge protection devices.
18.
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 Tables A and B. The
recommended line-to-line load unbalance is 50% or less.
19.
Output overcurrent protection and output disconnect switch are to be provided by the
user. Table H lists the maximum rating for continuous duty rated output circuit breakers
satisfying the criteria for both.
