3.6.3 CoolingDrives dissipate power in the form of heat. Adhere to thefollowing recommendations for effective cooling of theunits.• Maximum air temperature to enter the enclosuremust never exceed 40 °C (104 °F).• Day/night average temperature must not exceed35 °C (95 °F).• Mount the unit to allow for unhindered coolingairflow through the cooling fins. Seechapter 6.1.1 Clearances for correct mountingclearances.• Provide minimum front and rear clearancerequirements for cooling airflow. See the VLT®DriveMotor FCP 106 Operating Guide for properinstallation requirements.3.6.4 Aggressive EnvironmentsA drive contains many mechanical and electroniccomponents. All are to some extent vulnerable to environ-mental effects.NOTICEDo not install the drive in environments with airborneliquids, particles, or gases capable of affecting anddamaging the electronic components. Failure to take thenecessary protective measures increases the risk ofstoppages, thus reducing the life of the drive.Liquids can be carried through the air and condense in thedrive and may cause corrosion of components and metalparts. Steam, oil, and salt water may cause corrosion ofcomponents and metal parts. In such environments, useequipment with enclosure protection rating IP54.Airborne particles such as dust may cause mechanical,electrical, or thermal failure in the drive. A typical indicatorof excessive levels of airborne particles is dust particlesaround the drive fan. In dusty environments, useequipment with enclosure protection rating IP54 or acabinet for IP20/Type 1 equipment.In environments with high temperatures and humidity,corrosive gases, such as sulphur, nitrogen, and chlorinecompounds, cause chemical processes on the drivecomponents.Such chemical reactions rapidly affect and damage theelectronic components. In such environments, mount theequipment in a cabinet with fresh air ventilation, keepingaggressive gases away from the drive.Before installing the drive, check the ambient air forliquids, particles, and gases. These checks are done byobserving existing installations in this environment. Typicalindicators of harmful airborne liquids are water or oil onmetal parts, or corrosion of metal parts.Excessive dust particle levels are often found on instal-lation cabinets and existing electrical installations. Oneindicator of aggressive airborne gases is blackening ofcopper rails and cable ends on existing installations.3.6.5 Ambient TemperatureFor recommended ambient temperature during storageand operation, refer to chapter 6.5 Ambient Conditions andchapter 6.9 Derating According to Ambient Temperature andSwitching Frequency.3.6.6 Acoustic NoiseAcoustic noise originates from the following sources:• External fan• DC intermediate circuit coils• RFI filter inductorSwitching frequency MH1 MH2 MH3[kHz] [dB] [dB] [dB]5 55 55.5 52Table 3.9 FCP 106 Acoustic Noise Levels, Fan on,Measured 1 m (3.3 ft) from the Unit3.6.7 Vibration and ShockThe drive complies with requirements for wall- or floor-mounted units mounted at production premises, and inpanels bolted to walls or floors.The drive has been tested according to the proceduresdefined in Table 3.10.IEC 61800-5-1 Ed.2 Vibration test, Cl. 5.2.6.4IEC/EN 60068-2-6 Vibration (sinusoidal) - 1970IEC/EN 60068-2-64 Vibration, broad-band randomIEC 60068-2-34,60068-2-35, 60068-2-36Curve D (1–3) Long-term test 2.52 gRMSTable 3.10 Vibration and Shock Test Procedure ComplianceSystem Integration Design GuideMG03M302 Danfoss A/S © 12/2018 All rights reserved. 353 3
