NOTICE 
Protective circuit for the parallel connection of more than two power supplies 
For connection of more than two power supplies in parallel, additional measures must be 

taken to prevent high backward feeding currents in the event of a secondary device fault. 

For this purpose, a suitable protective circuit (e.g. decoupling diode or DC-conform circuit-

breaker) must be installed between each "+" terminal of the power supply and the common 

connection point.
