Observe the followingprecautions to help maintain the expected performance life and reliability during long-term storage.n Storage LocationTemperature and HumidityStore the drive in a location that is between -10 and +40 °C with a relative humidity of 95% or less. Do not store the drive indirect sunlight or where condensation or ice will form.Storage temperatures between -20 to +60 °C are allowed when storing the drive for approximately one month.Note: Package and store the drive during shipping to protect it from vibration and shock.Dust and Oil MistDo not store the drive in a dusty location or a location subject to oil mist.Corrosive GasDo not store the drive in a location subject to corrosive gas.Salt DamageDo not store the drive in a location subject to salt damage, such as near the ocean.Do not store the drive in adverse environments. Store all drives in storage rooms that are not subjected to adverse environmentalelements.Periodic Power ApplicationYaskawa recommends applying power to the drive once per year for at least 30 minutes to prevent the capacitors fromdeteriorating.When applying power after power has not been applied for more than two years, Yaskawa recommends using a variable powersource and gradually increasing the power from 0 V to the rated drive voltage over a period of 2 to 3 minutes. Apply powerfor at least 1 hour with no load to age the main circuit electrolytic capacitor.Wire the drive normally and check for drive faults, overcurrents, motor vibration, speed fluctuations, and other abnormalitiesduring operation after performing the above procedure.MCDriveRSTUVWVariable power sourceAC supplyFigure 2.1 Power Distribution Method2.2 Inspection170 YASKAWA ELECTRIC SIEP C710636 10C Z1000U HVAC MATRIX Drive Programming Manual
