3.15 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 component tests are carried out by the manufacturer. Field tests can be performed in the field
using suitable test equipment that ramps up the voltage with a slow ramp (2s rising and 2s falling). Connect
all input terminals and all output poles to each other before performing the tests. During the test, set the cut-
off current to the value shown in the table below.

We recommend connecting either the positive or the negative pole to the protective conductor system. This
avoids situations in which the load starts unexpectedly or cannot be disconnected if an unnoticed earth
leakage occurs.
