8. dvice regarding electric strength tests Earth Leakage The EMI suppression circuits causes earth leakage currents which may be to the maximum allowable of 3 5mA Ventilation High operating temperature is a major cause of power supply failures for example it has been well documented that a 10 C rise in the operating temperature of a component will halve its expected life Therefore always ensure that there is adequate ventilation for the equipment Batteries and cooling fans also suffer shortened lifetimes if subjected to high ambient temperatures both should be included in a routine maintenance schedule to check for signs of reduced effi ciency Water Dust Every effort must be made in the installation to minimise the risk of ingress of water or dust Water will almost always cause instant failure The effects of dust are slower in causing failure of electronic equipment but all electrical equip ment should be cleaned free of any dust accumulation at regular intervals Electromagnetic Interference EMI Switching power supplies and converters inherently generate electrical noise All wiring should be as short as practica ble and segregated from all equipment wiring which is sensitive to EMI Residual noise can be reduced by looping DC wiring through ferrite cable sleeves These are most effective as close to the power supply as possible and as many turns of the wire taken through the core and in the same direction as the core will ac
