Free Access Underfloor Connection of Power Cable

If the height of underfloor is less than 300mm (11.8 in.), the power distribution is set to sideways.

FIGURE 2.32 When Underfloor Height is less than 300mm (11.8 in)

The connector format and cable bend radius of power cable are considered at the time of connecting the
power cable of power distribution box (or base cabinet, PCI_Box) under the free access floor. It is
recommended that the under floor height is 300 mm (11.8 in) or more.
The recipient power distribution should be arranged near the device.

FIGURE 2.33 When the under floor height is 300 mm (11.8 in) or more.

Remarks
The above figure shows an example of 19-inch rack made by Fujitsu Limited mounted with the device.
2.6 Cutoff Characteristics of Distribution Panel (At the time
of connecting power distribution box)
At the time of connecting the distribution panel through power distribution box, protection should be
coordinated so that the breaker of the device (or power distribution box) trips before the breaker of the
distribution panel trips. Such protection should be maintained. Therefore, the distribution panel should have
the characteristic conditions shown in
It is necessary to use Distribution panel Breaker suitable to these conditions.
