Adjusting output voltage beyond the stated range may cause overvoltage protection (OVP) to operate,
whereby the output will latch off. To reset for normal operation simply adjust the potentiometer to reduce the
output voltage to within its range and cycle the input off then on.
All outputs are SELV except under the following circumstance: Outputs connected in series are non-SELV if
the total output voltage exceeds 60Vdc
If the total voltage of outputs connected in series exceed the 60Vdc SELV limit then all outputs must be
considered non-SELV.
Non-SELV outputs are hazardous and must not be made user accessible. Consideration must be given to
service engineers making inadvertent contact with the output terminals in the end equipment.
All outputs have functional spacing to earth, and due consideration must be given to this in the end product
design.
Parallel operation - Up to 2 units may be connected in parallel, output loading 10-90% in parallel mode.
Cooling for unit
The unit must be mounted on a DIN rail and must not be inverted, the output connection uppermost.
