Special Safety Instructions
Standard Specific Safety Instructions:
Whilst all individual outputs are classed as SELV outputs in accordance with the standard
IEC/EN/UL/CSA60950-1 (<60Vdc or 42.4V peak), seriesed combinations of these outputs may exceed these
values and become hazardous output voltages.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.

Level of Insulation:
Dielectric Strength testing is carried out as follows:
Primary mains circuit to earth: - 1500KVAC, 2121VDC
Primary mains circuits to secondary: 3kVAC, 4142VDC*
*This test is not possible with Y capacitors fitted to the unit as damage to these
capacitors will occur. It is also necessary to short circuit the output together and to earth.
