4.5 Connecting the system unit to the mains

configuration, it is fitted with three power supply units.
V CAUTION!
● Read the information on determining how many power supply units
are required (see "Hot-plug power supply units" on page 126).
● The power supply units automatically adjust to a mains voltage
between 100 - 240 V. The system unit may only be used if the local
mains voltage is within the voltage range of the system.
● The 2880 W power supply units may only be connected to 16 A power
outlets, a UPS, a 32 A power distribution unit, or CEE sockets. When
ordering the system unit, you must specify which socket type is
available at the installation location, so that the cables with the
appropriate C19 connectors can be supplied.
● For the Japanese market:
The 918W power supply units may only be connected to NEMA L6-
30, IEC 60320-C20, or NEMA 5-15 sockets.
