19. DIELECTRIC STRENGTH
The signal port (relay contacts and inhibit input) are floating and separated from the power port (input voltage,
output voltage, center-tap terminal and temperature sensor).
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 all poles of the
power port terminals together as well as all poles of the signal port before conducting the test. When testing, set the
cut-off current settings to the value in the table below. The following isolation tests were performed:
