When connecting a new enclosure, if the total current consumption of power cords that connect to outlets
OUT1 to OUT4 exceeds 12A, connect to OUT5.
When the total current consumption of power cords that connect to outlets OUT5 to OUT8 exceeds 12A, con-
nect to the next power distribution unit.
For details on the current consumption of each power cord for each type of enclosure, refer to "Outlet/Socket
Specifications
" (page 38).

Connect to the outlets using the connection order
which is the same as the installation order in the rack.
Since the rated current has been
exceeded, the same connection
is not available. Connect to
the next power distribution unit.

For the following combinations, the total current consumption of outlets OUT1 to OUT4 or the total current
consumption of outlets OUT5 to OUT8 exceeds 12A and then the connection fails.
