NOTICEMOTOR THERMISTOR SENSOR MONITORINGVLT® AutomationDrive units with the VLT® PTCThermistor Card MCB 112 option are PTB-certified forpotentially explosive atmospheres.4.5 Installation and Cooling RequirementsNOTICEImproper mounting can result in overheating andreduced performance.Installation requirements• Locate the unit as near to the motor as possible.See chapter 9.5 Cable Specifications for themaximum motor cable length.• Ensure unit stability by mounting the unit to asolid surface.• Enclosures E3h and E4h can be mounted:- Vertically on the back plate of the panel(typical installation).- Vertically upside down on the backplate of the panel.1)- Horizontally on its back, mounted onthe back plate of the panel.1)- Horizontally on its side, mounted onfloor of the panel.1)• Ensure that the strength of the mounting locationsupports the unit weight.• Ensure that there is enough space around theunit for proper cooling. Refer tochapter 9.9 Enclosure Airflow.• Ensure enough access to open the door.• Ensure cable entry from the bottom.1) For non-typical installation, contact the factory.Cooling requirements• Ensure that top and bottom clearance for aircooling is provided. Clearance requirement:225 mm (9 in).• Provide sufficient airflow flow rate. See Table 4.1.• Consider derating for temperatures startingbetween 45 °C (113 °F) and 50 °C (122 °F) andelevation 1000 m (3300 ft) above sea level. Seethe design guide for detailed information.The drive utilizes a back-channel cooling concept thatremoves heat sink cooling air. The heat sink cooling aircarries approximately 90% of the heat out of the backchannel of the drive. Redirect the back-channel air fromthe panel or room by using:• Duct coolingBack-channel cooling kits are available to directthe heat sink cooling air out of the panel whenIP20/Chassis drives are installed in Rittalenclosures. Use of these kits reduce the heat inthe panel and smaller door fans can be specified.• Back-wall coolingInstalling top and base covers to the unit allowsthe back-channel cooling air to be ventilated outof the room.NOTICEFor E3h and E4h enclosures (IP20/Chassis), at least 1door fan is required on the enclosure to remove the heatnot contained in the back-channel of the drive. It alsoremoves any additional losses generated by othercomponents inside the drive. To select the appropriatefan size, calculate the total required airflow.Secure the necessary airflow over the heat sink.Frame Door fan/top fan[m3/hr (cfm)]Heat sink fan[m3/hr (cfm)]E1h 510 (300) 994 (585)E2h 552 (325) 1053–1206 (620–710)E3h 595 (350) 994 (585)E4h 629 (370) 1053–1206 (620–710)Table 4.1 Airflow Rate4.6 Lifting the UnitLiftingAlways 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 3.2 Power Ratings, Weights, andDimensions for the weight of the differentenclosure types.• Maximum diameter for bar: 20 mm (0.8 in).• The angle from the top of the drive to thelifting cable: 60° or greater.Mechanical Installation VLT® AQUA Drive FC 20214 Danfoss A/S © 01/2017 All rights reserved.
