3.1 Connecting the Power Cables
3.1.2
Power cable connection for the PRIMEPOWER900 main unit
(model name: PW0X0CR1x, PW0X0CR6x)
This section explains the power cable connection for the PRIMEPOWER900 main
unit (model name: PW0X0CR1x, PW0X0CR6x).
The number of power cables required for the main unit depends on the power supply
configuration of the main unit. Three configurations for power cable connections are
described below:
l
For non-redundant configuration of power supply unit (PSU)
l
For N+1 redundant configuration of power supply unit (PSU)
l
For dual power feed configuration
(1)
For non-redundant configuration of power supply unit (PSU)
Use the following information to connect power cables for a non-redundant PSU
configuration.
• Number of power cables
l
Two or three power cables (IEC320) are provided for the main unit power
distribution box (one each for the main unit, the first system board, and the second
system board).
l
For information about correctly connecting a cable, refer to the
“PRIMEPOWER900 Installation Planning Manual”
(U41297-J-Z816-x-76/C120-H013EN).

For a unit using software-based automatic power control, do not set the MODE
switch on the operator panel to UNLOCK or LOCK. If a main line switch in the
power distribution box is switched off and on while the MODE switch is set to
UNLOCK or LOCK, the unit may be powered on automatically as soon as the
main line switch is switched on. To avoid this situation, set the MODE switch to
MAINTENANCE.
