Insulation Resistance at 1000V DC
The insulation resistance will not be less than 10 megohms between mains input to frame and
all isolated outputs, and all combinations of isolated output to isolated output.
6.2.
Applied Voltage Test
Mains input to frame: 2.0kV RMS for 1 minute.
All combinations of isolated output to isolated output and isolated output to frame: 1.0kV for 1
minute
