Module limitations
•
All outputs are SELV except under the following circumstance: Outputs connected in series are non-SELV if the
total output v 30% of the max. Rated output voltage of the output with the highest rated voltage exceeds
60Vdc (the 30% addition allows for a single fault in any one individual channel).
•
If the total voltage of outputs connected in series exceeds the 60Vdc SELV limit then all outputs must be
considered non-SELV.
•
The total voltage of outputs connected in series must not exceed 160V.
•
Non-SELV outputs are hazardous and must not be made user accessible. They must be guarded or a deflector
fitted during installation to avoid a service engineer making inadvertent contact with the output terminals, or
dropping a tool onto them.
•
All outputs have operational spacings to earth, and due consideration must be given to this in the end product
design.
•
Adjusting output voltage beyond the stated range may cause over voltage protection (OVP) to operate, whereby
the output will turn off. To reset OVP, turn back the output voltage adjustment and remove the mains supply for 30
seconds and then switch back on.
