Electrical Specifications
This section provides electrical specifications for the IOX cabinet.
AC Power Requirements
The operating input voltage range is 176-264 VAC rms at line frequencies of 47-63 Hz. The XPC accepts one
or two single phase inputs. The nominal input voltage range is 200-240 VAC rms.
Table A-5 lists the AC power requirements for a IOX cabinet. This table provides information to help you
determine the amount of AC power needed for your computer room.
For redundant AC operation (n+1=2) utilizing two input power grids, one single phase is received from power
grid no. 0 and one single phase from power grid no. 1. Note the input power grids are not required to be equal
in voltage or equal in phase angle.
