Dielectric strength
The output voltage is earth-free and has no ohmic connection to earth.
The output is isolated from the input by double or reinforced insulation.
Type and routine 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 (2 s up and 2 s down).
- 1. Connect all input terminals and all output poles to each other before performing the tests.
- 2. When testing, set the cut-off current settings.to the value in the table below.
- 3. We recommend connecting either the positive pole, the negative pole or another part of the output circuit to the protective conductor system. This avoids situations in which the load starts unexpectedly or cannot be disconnected if an unnoticed earth leakage occurs.
- 4. To test EtherCAT interfaces, all eight lines of the respective RJ45 plug must also be short-circuited in order to apply the test voltage.
B*) When testing the EtherCAT inputs and outputs, ensure that the maximum voltage between the EtherCAT cables and the output is not exceeded (column "E-IN" and "E-OUT").
E*) All tests are performed separately on EtherCAT inputs and outputs.
