NOTE
Bypass breakers are not required for IOM configurations.
There is no manual DC disconnect device within the UPS.
A battery disconnect switch is recommended, and may be required by NEC or 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 customer. Table 3‐16 lists the maximum
rating for continuous‐duty rated circuit breakers satisfying the criteria for both.
Recommended breaker size is based on a maximum full load discharge time less than
3 hours. For longer discharge times a larger breaker may be required.
