Dielectric strength

The input and output voltages are potential-free and have no resistive connection to ground.

The input and output voltages have the same electrical reference; there is no electrical isolation.

Type and component tests are carried out by the manufacturer. Field tests can be carried out using appropriate test devices that apply the voltage with a slow ramp (2 seconds up and 2 seconds down). Prior to the test, connect all input terminals with one another as well as all output poles. For the test, set the cut-off current to the value in the table below.
