current due to the inductive load.
Also when the remote sensing function set
to FB, check the feedback cable connects
correctly. (See
8.2.2 )
50 Output Overcurrent [RMS] Output Off The output current RMS value is excessive
on a module in the power unit. This may
occur when the output terminal is
short-circuited.
