Installationandcommissioningofthedevicemayonlybecarriedoutbyqualiedpersonnelwhoareadequately
trainedonthefeaturesandtheuseofthedevice.
Stay away from potentially active parts.
Disconnecttheenergysourcesbeforeperformingoperationsonthedevice.Allowadequatedischargingtimefor
anyresidualenergybeforeaccessingthedevice.Useasuitablemeasuringinstrumenttocheckforresidualvoltage
beforecomingintocontactwithpotentiallyactiveparts.
Access the internal sides of the device only in cases of absolute necessity, such as
maintenance or repairs.
Wait until the device is completely de-energised before opening the device or removing the
panel for maintenance.
All personnel working on the device and its associated circuits must be qualied and trained
in rst aid and cardiopulmonary resuscitation (CPR) techniques.
1.2 EC directive
ThisdevicecomplieswiththerequirementsoftheECDirectives:

The CCRs DIAM3200 of OCEMAireld Technology are optimized static power supplies, controlled by IGBTs
(insulatedgatebipolartransistors),designedtomaintainaconstantoutputcurrent,independentofloadorpower
supplyuctuations.
Theoutputcurrentremainsconstantwithanaccuracyof100mAformainsvoltageuctuations±10%andwithall
loadsbetween0and100%andupto30%oftransformerswithopensecondary.
Thankstoitsuniquepowerarchitecture,theCCRsDIAM3200ofOCEMAireldTechnologyintroducenodistortion
ordegradationofthepowerfactor,whichremainsthatoftheload.Theharmoniccontentreectedonthesupply
networkisthereforeparticularlylow,overtheentireoutputcurrentrangeandforanyload.
Noadaptationtotheloadviasocketsisnecessary.ThedigitalprocessingcapabilityoftheDSPprocessorallows
ittobeadaptedtoanytypeofload:LEDxtures,halogenxtures,electronicconvertersorcombinedsystems.
TheCCRsDIAM3200ofOCEMAireldTechnologyperformanautomaticcalibrationthatavoidsanyanalogue
adjustmentduringmaintenance.AsimpleandintuitiveHMIuserinterfaceallowscleardisplayofalarmindications,
oftheCCRstatusandofallrelevantparameters.
Thesedevicesarespeciallydesignedforsupplyingairportvisualaids,incompliancewithallinternationalstandards.
Thedeviceisdesignedincompliancewith:
●ICAOAirportDesignManual,Part5;
●IEC61822(CCR),61821(Maintenance).
Immediately check for visible damages of the device and of the containing parts. Carefully
unpack the device and check for visible damages.
Store all the components in the original packaging until the time of installation.
Take care not to damage sheet metal parts, cables and internal components.
The device described in this manual is designed to power series circuits intended for airport
lighting of runways, taxiways and aircraft aprons.
