6ES5 955-3LF41 24V o.k. OFF

VincentVega Posts: 1 Rating: (0)	Hi. When powering up a 6ES5 955-3LF41 Power supply stand-alone ( not mounted in Rack ) the 24V o.k. LED stays OFF. Measuring approx. 18V on "Voltage Monitor", i´d like to know if the PS is defective or has to be mounted in a Rack to switch to normal operation. RB/MB is low, Voltage low is OFF when connecting 24V OUTPUT to 24V extern INPUT. Thank you in advance !
