Connection Diagrams
The following diagrams show connections between the power distribution units, the ETERNUS AB/
HB and the power sockets of the distribution boards.
Do not connect just one power distribution unit to multiple ETERNUS storage systems. In addition,
do not connect just one circuit protector of a power distribution unit to multiple ETERNUS storage
systems.
When power cords are connected to a single power supply line, the connections are more secure if
a one-to-one connection is made between each power cord and circuit protector of the distribu-
tion board.
