Table 5-9: Recommended bypass and output circuit breaker ratings

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 switch
should be installed between the battery and the UPS.
External DC input overcurrent protection and disconnect switch for the remote battery location is to be
provided by the user. Table 5-10 lists the maximum rating for continuous-duty rated circuit breakers
satisfying the criteria for both.

Table 5-10: Recommended DC input circuit breaker ratings

Rated battery current is computed at 1.7 volts per cell. The battery wiring used between the battery
and the UPS should not allow a voltage drop of more than 1% of nominal DC voltage at rated battery
current. If the conductors used for DC input from the battery cabinets to the UPS are those provided by
the UPS manufacturer, and the UPS and battery cabinets are manufactured by the same supplier, then
it is acceptable if they do not meet the noted minimum conductor sizes.
