Safety level of output voltage

The output voltage is regarded to be SELV (EN 60950-1) or PELV (EN 60204-1, EN

62477-1, IEC 60364-4-41) if the input voltage fulfills the requirements for a SELV

source or PELV source.

Class of protection

III

PE (Protective Earth) or chassis connection not required

PE resistance

< 0.1Ohm

between housing and chassis-ground terminal

The input and output voltages have the same reference, are floating and have no ohmic connection to ground.

Type and factory 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 (2s up and 2s down). Connect input/output

and signal terminals together before conducting the test.

When testing, set the cut-off current settings to the value in the table below.
