SAFETY
For safe operation, the unit must be installed in an enclosure which prevents accidental contact with hazardous voltages, by providing appropriate
insulation or guarding. If the enclosure is made of a conducting material or the internal surfaces have a conductive coating, ensure that no part of
the power supply will come into contact with it, and maintain an air gap clearance of minimum 10mm. The mains lead to the unit must be fused with
a 100mA fuse. In general, it is the responsibility of the user to ensure that the incorporation of the power supply unit into the OEM equipment
conforms to the relevant sections of EN 60742, in accordance with the Low Voltage Directive (LVD 93/68/EEC).
