First connect the C19 connector of the power cables to the power supply 
units of the basic unit (1), and then plug the power plug (2) into the USV, 
power distribution unit (PDU) or into an external socket.

CAUTION!
Always connect the power cable to the power supply units first, and then 
to the mains.

Please make sure that each of the power supply units is connected to a 
different phase. This will provide you with additional phase redundancy 
for high availability configurations. If one phase has failed, the power 
supply units connected to the other phases keep active. You can get full 
phase redundancy with up to three power supply units. With four power 
supply units, two of them are to be connected to one phase (see also 
Phase redundancy is possible in regions, where a single phase provides 
200 - 240V; in other regions with lower single phase voltage, two phases 
must be coupled and complete phase redundancy thus is not possible.
