that connect to outlets OUT5 to OUT8 within 12A for each power distribution unit.
•
When connecting a new enclosure, if the current capacity totaling the current consumption value of power
cords that connect to outlets OUT1 to OUT4 exceeds 12A, connect to OUT5.
When the current capacity totaling the current consumption value of power cords that connect to outlets OUT5
to OUT8 exceeds 12A, connect to the next power distribution unit.
