2.4 BCS-PDU electrical connections
Two different PDU versions are available, one for North American and one for European
electrical system.
WARNING!
Never use the North American PDU with European electric system: the phase splitting
is different: EU is line to neutral (230 VAC), US is line to line (208 VAC).
The PDU unit must be connected to three-phase electric power. Two modes of connection
are possible, depending on whether the logic line is connected to an Uninterruptible Power
Supply (UPS).
Note: the UPS unit is not provided with the BCS unit.
