CAUTION
To reduce the risk of fire, connect only to a circuit provided with
maximum input circuit breaker current ratings from Table 7 in
accordance with local regulations.
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 5. The recommended line-to-line load unbalance is 50% or less.
Readily accessible disconnect devices (rectifier, bypass and output
overcurrent protection and rectifier, bypass and output disconnect
switches) are to be supplied by the customer. Table 7 lists the
recommended rating for the circuit breakers or fuses.
There is no DC disconnect device within the UPS. A battery disconnect
switch is recommended, and may be required by local codes when
batteries are remotely located. The battery disconnect device should be
installed between the battery and the UPS in the immediate vicinity of
the UPS.
For parallel systems sharing a common battery source, there must be a
disconnection device between the UPS and battery for each UPS.
External DC input overcurrent protection and disconnect switch for the
remote battery location is to be provided by the user. Table 7 lists the
maximum rating for continuous-duty rated circuit breakers satisfying the
criteria for both.
