10 Dielectric Strength, Isolation, Leakage Current
The output is floating and has no ohmic connection to the ground.
The following type and factory tests are conducted by the manufacturer. The test duration is 60s
for type tests and 5s for the factory tests.

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). Prior to the field test, special treatment of the
unit may be necessary. Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings of the test equipment to a
value larger or equal than 10mA. Optionally, a DC test voltage can be applied too. In such
cases, multiply the AC test voltages with the factor 1.41.
The test duration for field tests should not exceed 10s, since every high-pot test adds
extraordinary stress to the unit.
