NOTE Because of the future upgradability to a fully rated 900 kW UPS with the addition of the FI-UPM, Eaton recommends
using the breaker size specified for a 1100 kW UPS.
There is no manual DC disconnect device within the UPS.
A battery disconnect switch is required for battery systems and may also be required by NEC or local codes.
The battery disconnect switch should be installed between the battery and the UPS.
Battery voltage is computed at 2 volts per cell as defined by Article 480 of the NEC. Rated battery current is
computed at 2 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.
External DC input overcurrent protection and disconnect switch is to be provided by the customer.
and
list the maximum ratings for continuous–duty rated circuit breakers satisfying the criteria for both.
Recommended disconnect size is based on a maximum full load discharge time less than 3 hours. For longer
discharge times a larger disconnect may be required.
