12. Protection Features
Output over-current protection not included
Reverse input polarity protection included unit does not start when input voltage is reversed
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.6mm e.g. screws, small parts
Over-temperature protection not included
Input transient protection not included
Output transient protection included see EMC section
Internal input fuse not included
13. Safety Features
Input / output separation no galvanic separation 200V epitaxial diode between input and output
Safety level of output voltage The output voltage is regarded to be SELV (EN 60950-1) or PELV (EN 60204-1, EN
50178, IEC 60364-4-41) if the input voltage and the voltage which is applied to the
alarm contacts fullls 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
14. Dielectric Strength
The input and output voltages have the same reference, are oating and have no ohmic connection to ground.
Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the eld using the
appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down).
Connect input/output/signal terminals together before conducting the test.
When testing, set the cut-off current settings to the value in the table below.
