Parallel / Series Operation 
This section describes the basic operations required to operate the 
power supply in series or parallel. Operating the PSU series in 
parallel increases the total current output of the power supply units. 
When used in series, the total output voltage of the power supplies 
can be increased.  
 
When the units are used in parallel or in series, a number of 
precautions and limitations apply. Please read the following 
sections before operating the power supplies in parallel or series.
