POWER SUPPLIES DUAL TRACKING OUTPUTS INSTALLATION OPERATION
Threaded holes bottom side surface used mounting (except, side mounting TH11 case size), supply rear mounted using same holes that attach rear cover plate. accessory Mounting (model Gold power supplies model Narrow Profile power supplies) available enable mounting power supply when opposite side mounting surface inaccessible. Even relatively small amount flowing around through power supply will significantly reduce rise temperature resulting from operation, therefore temperature critical components within improving both reliability stability. Avoid blocking flow through vented surfaces. perforated bottom supply mounted solid surface, spacers least 3/16" thick between surface which fastened, permit convection flow, punch ventilation holes mounting surface. Allow free circulate around heat sinks. Space least inch away from surrounding objects. Make connections before applying input power. SENSING TERMINALS MUST CONNECTED output terminals, either barrier strip power supply load. Failure have sense terminals connected will affect output voltage (usually causing higher than rating supply, unadjustable), result permanent damage both power supply load. voltage drops output voltage leads (which degrade regulation) objectionable, local sensing used; leave place jumpers provided with power supply barrier strip (connecting +SENS terminal -SENS terminal). However, best possible regulation load required, then remove jumpers additional leads connect sense terminals output leads load, shown schematic. This configuration permits power supply sense compensate voltage actually across load. Note that remote sensing capable compensating only limited wiring drops. voltage across load, plus voltage drops through wiring, must within output voltage range supply voltage load remain within load regulation specification. there possibility voltage from another source (another power supply, battery, transients, etc.) being applied power supply's output terminals, protect power supply using diode series with lead another series with lead. attempt directly parallel outputs power supplies. This would result current flowing from higher-set output into lower-set output, probable damage both circuits. Outputs used series obtain higher voltage provided that reverse-biased diode, having current ratings exceeding combined output, used across each output; however, keep mind that output current drawn cannot exceed output current rating lowest rated supply used. Frequent fuse failure symptomatic power supply overload, short circuited output, tripped overvoltage protector, power supply failure. overfuse; this result damage power supply. input power contains large voltage spikes (`noise') induced switching high currents, inductive loads, electro-mechanical components, etc., input power leads supply should include some means transient suppression. Otherwise, portion noise coupled through supply load. Also, supply could damaged. means suppression that easiest install capacitor metal oxide surge suppressor (MOV) across input terminals supply. extremely severe cases, chokes series with each side line also required. These power supplies operate constant voltage sources when used load current equal less than their ratings. power supply overloaded, current limit circuit will automatically reduce output voltage, will then attempt recover normal operating point. Therefore, TRANSITORY OVERLOAD RESULTS MOMENTARY DROP OUTPUT VOLTAGE. However, overload still present when voltage attempts recover, voltage will continue alternately drop recover, which will appear sawtooth oscillation output. operate power supply this mode; reduce load that output current equal less than rating supply will drawn.

SPECIAL MEASURES LIMITATIONS
maintain compliance with Voltage Directive, following special measures limitations must observed when product placed into service: Marked Voltage Directive. Evaluated Pollution Degree environment. Intended connection Class TN-S power system. Models with outputs volts less considered have SELV outputs. Models with outputs greater than volts considered have hazardous voltage outputs should located Operator Access area product. Models with output ratings less than 240VA considered have nonhazardous energy levels. Models with output ratings 240VA greater considered have hazardous energy levels. Models without built-in fuse require external fuse used ungrounded (hot) side line. catalog electrical mechanical specifications. Ground terminal must bonded protective earth. Intended installed within end-use equipment.
REAR MOUNTING cases, remove original screws(4) 8-32 Type self-tapping screws. They should extend least 5/16" (0.312") into power supply case. REAR MOUNTING cases, remove original 6-32 screws(4). These screws then used mounting, provided they extend least 1/4" (0.250") into power supply case.
