ETERNUS AB/HB Installation
Outlet/Socket Specifications
Required Number of Outlets/Sockets
The number of power outlets/sockets required to install the ETERNUS AB/HB depends on the num-
ber of shelves and power distribution units.
It is recommended that the power cords of the shelves 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 shelves.
■
Without Power Distribution Units
Two power sockets are required for each controller shelf and drive shelf.
■
With Power Distribution Units
Two power sockets are required for each power distribution unit.
Circuit Protectors
Protection coordination must be secured between the distribution board circuit protectors and the
ETERNUS AB/HB or power distribution units to protect the ETERNUS AB/HB by blocking the failed
circuit immediately when a power supply input error occurs.
Distribution board circuit protectors must satisfy the following required conditions and breaking
characteristics.
