4.1.2 Cable Connection
■ Power supply connection
It is recommended that the power cords (AC cables) of the enclosures are connected to the power distribution
units that are installed in the same rack. Secure the necessary number of power outlets within the same rack
to avoid connecting power cords to power outlets in different racks.
It may be necessary to purchase additional power distribution units depending on the installation locations of
enclosures.
The length of the AC output cable that is supplied with the power distribution unit is 3m.
