● For Power Distribution Unit (Six Outlets) Connections
The following diagram shows an example of a power supply connection when a power distribu-
tion unit (six outlets) is used.
- Current consumption of each outlet: 16A or less
- Current consumption of each inlet cable: 24A or less
Figure 21 Example of a Power Supply Connection When a Power Distribution Unit (Six Outlets) Is
Used
PSU: Power Supply Units
CP: Circuit Protectors
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.
