1. ETERNUS AX/HX Installation
Outlet/Socket Specifications

Required Number of Outlets/Sockets

The number of power outlets/sockets required to install the ETERNUS AX/HX depends on the number 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 connect-
ing 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 AX/
HX or power distribution units to protect the ETERNUS AX/HX 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.
■ Required Conditions
The distribution board circuit protectors must satisfy the required conditions that are listed below.
