6. erature 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 This is particularly important where internal fans are fitted 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 accommodate Fuse ratings Check that the wiring and fuses or MCBs match the rating of the PSU or converter Adequate fuse protection o
7. f battery circuits is very important owing to the large potential currents available from batteries Connection polarity It is critical to check the polarity carefully when connecting DC power supplies and chargers to equipment Boost chargers and some float chargers usuall have reverse polarity protection RPP which can be electronic non destructive or by an internal fuse which needs to be replaced if a battery is connected in reverse Glossary of terms used in our user manuals PSU power supply unit BCT battery condition test ECB electronic circuit breaker ELVD electronic low voltage disconnect RPP reverse polarity protection EMI electromagnetic interference SNMP Simple Network Management LAN local area network DOD depth of discharge Protocol Specifications are subject to change without prior notice 2 ovative energies 1 INTRODUCTION The SR500A version described in this user manual is a DC DC converter suitable for 110VDC input 2 CONNECTIONS If used as a float charger always connect the positive output of the power supply to the positive terminal of the battery The charger may be permanently connected to float charge lead acid batteries but it is essential to periodically check the electrolyte level of flooded cells as there is always some evaporation Where screw plug in terminals are fitted on the 24V model there are two terminals provided for each polarity and both terminals must be used This
