Product HANDBOOK KPSB25 Series
Standard Specific Safety Instructions:
Whilst all individual outputs are classed as SELV outputs in accordance with the standard
IEC/EN/UL/CSA62368-1 (<60Vdc or 42.4V peak), when connected in series, combinations of these outputs
may exceed these values and become hazardous output voltages. See output parameter section.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
