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.
| A | |
|---|---|---|
Type test | 60s | 500 Vac |
Component test | 5s | 500 Vac |
Field test | 5s | 500 Vac |
Settings for the field test cut-off current | > 2 mA | |
