Maintenance work istherefore not usually required. Local conditions and <strong>com</strong>panyprocedures may require regular inspection.In general we re<strong>com</strong>mend the following regular checks:Item Inspect for … Interval Method Values, remedies Own measuresEnvironmentExtreme temperatures andhumidityMonthlyThermometer,hygrometerMounting location Noise and vibration Monthly Visual and acousticcheckMains powersupplyVoltage fluctuations Monthly Measure voltagebetween terminalsL1 and N or betweenL1, L2 and L3Insulation Sufficient resistance Annually Measure resistancebetween PE andterminalsAmbient temperaturebetween –10 to +40 o C,non-condensingCompatibility with theenvironment for electricalcontrollers.DF51-320, DF51-322:200 to 240 V 50/60 HzDF51-340:380 to 460 V 50/60 HzAt least 5 MOInstallation Firmness of screws Annually Torque spanner M3: 0.5 to 0.6 NmM4: 0.98 to 1.3 NmM5: 1.5 to 2 NmPower sectionterminalsComponents(general)Secure connections Annually Visual inspection No abnormalitiesOverheating Annually OvertemperaturesignalAmbient temperature,mounting position, fan:no trippingCapacitors Leakage, deformation Monthly Visual inspection No abnormalitiesResistors Cracks, discolouration Annually Visual inspection Resistance measurementFanEnclosureGeneralVibration, unusual noise,dustDirt, dust, mechanicaldamageOdour, discolouration,corrosionMonthlyVisual inspection,function testRemove dust, rotate byhandAnnually Visual inspection Remove dirt and dust,replace if damagedAnnually Visual inspection Normal appearance,inspection of generalambient conditions forelectronic devicesDisplays, LEDs Legibility Monthly Visual inspection Correct function of allLED segments189
