9 Mechanical Installation Considerations9.1 StorageStore the drive in a dry location. Keep the equipmentsealed in its packaging until installation. Refer tochapter 7.5 Ambient Conditions for recommended ambienttemperature.Periodic forming (capacitor charging) is not necessaryduring storage unless storage exceeds 12 months.9.2 Lifting the UnitAlways lift the drive using the dedicated lifting eyes. Toavoid bending the lifting holes, use a bar.WARNINGRISK OF INJURY OR DEATHFollow local safety regulations for lifting heavy weights.Failure to follow recommendations and local safetyregulations can result in death or serious injury.• Ensure that the lifting equipment is in properworking condition.• See chapter 4 Product Overview for the weightof the different enclosure sizes.• Maximum diameter for bar: 20 mm (0.8 in).• The angle from the top of the drive to thelifting cable: 60° or greater.130BF685.10Illustration 9.1 Recommended Lifting Method9.3 Operating EnvironmentIn environments with airborne liquids, particles, orcorrosive gases, ensure that the IP/Type rating of theequipment matches the installation environment. Forspecifications regarding ambient conditions, seechapter 7.5 Ambient Conditions.NOTICECONDENSATIONMoisture can condense on the electronic componentsand cause short circuits. Avoid installation in areassubject to frost. Install an optional space heater whenthe drive is colder than the ambient air. Operating instandby mode reduces the risk of condensation as longas the power dissipation keeps the circuitry free ofmoisture.NOTICEEXTREME AMBIENT CONDITIONSHot or cold temperatures compromise unit performanceand longevity.• Do not operate in environments where theambient temperature exceeds 55 °C (131 °F).• The drive can operate at temperatures down to-10 °C (14 °F). However, proper operation atrated load is only guaranteed at 0 °C (32 °F) orhigher.• If temperature exceeds ambient temperaturelimits, extra air conditioning of the cabinet orinstallation site is required.9.3.1 GasesAggressive gases, such as hydrogen sulphide, chlorine, orammonia can damage the electrical and mechanicalcomponents. The unit uses conformal-coated circuit boardsto reduce the effects of aggressive gases. For conformal-coating class specifications and ratings, seechapter 7.5 Ambient Conditions.9.3.2 DustWhen installing the drive in dusty environments, payattention to the following:Periodic maintenanceWhen dust accumulates on electronic components, it actsas a layer of insulation. This layer reduces the coolingcapacity of the components, and the components becomeMechanical Installation Con... VLT® AQUA Drive FC 20268 Danfoss A/S © 05/2017 All rights reserved. MG22B10299
