Replacing External
Battery Enclosure(s)
For additional runtime, some ON Series m UPSs can
use extra batteries housed in a separate enclosure.
The UPS power module and battery enclosure(s) are
shipped separately.
NOTE:
The UPS and attached loads may remain
powered ON during the battery enclosure(s)
replacement procedures.
The batteries inside the external battery enclosure(s)
are not user-replaceable. The entire battery enclosure
must be replaced or the enclosure may be returned to
ONEAC for battery replacement.
To disconnect the battery cable coming from an
external battery to the UPS or another external
battery, squeeze the two locking “ears” on the sides
of the battery connector and pull straight out (see fig.
10).
