15. temperature is a major cause of power supply failures for example a 10 C rise in the operating tempera ture of a component will halve its expected life Therefore always ensure that there is adequate ventilation for the equipment Batteries in particular suffer shortened lifetimes if subjected to high ambient temperatures 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 cores 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 accommodate External fuse protection Fuses or circuit breakers must be used in all battery circuits to protect against short circuits External fuses should be used for power supplies chargers even though they are usually internally protected Connection polarity It is critical to check the polarity carefully when connecting DC
