13. Dielectric Strength
The input and output voltages have the same reference, are floating and have no ohmic connection to ground.
Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the
appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect input/output
terminals together before conducting the test.
When testing, set the cut-off current settings to the value in the table below.
