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.

Safety Approvals:

UL508

UL/cUL60950-1 (2

IEC / EN60950-1(2

Edition)

CE marking when applied to any DPP120-xx-3 product indicates compliance with the Low Voltage Directive

(2006/95/EC) in that it complies with EN60950-1 (2

Edition).

Fusing: Internal fuses (F1): Single fuse each phase, T2AH, 600V

Symbols:

AC EARTH N – Neutral L – Live

If the earth terminal of the DPP120-XX-3 PSU is connected to the main incoming earth conductor of the end

equipment, the installer must cover the earth symbol with a label bearing the earth symbol of IEC60417-5019.
