If you have special questions, consult ebm-papst forsupport.3.5 Mounting dataFor screw clearance, see Chapter 3.1 Product drawing; Secure the screws against unintentional loosening (e.g. use self-locking screws).Strength class ofscrews8.8Any further mounting data required can be taken from the product drawing.3.6 Transport and storage conditions; Use the device in accordance with its degree of protection.Max. permittedambient temp. formotor (transport/storage)+80 °CMin. permittedambient temp. formotor (transport/storage)-40 °C3.7 Electromagnetic compatibilityEMC immunity tointerferenceAccording to EN 61000-6-2 (industrialenvironment)EMC circuit feedback According to EN 61000-3-2/3EMC interferenceemissionAccording to EN 61000-6-4 (industrialenvironment)If several devices are switched in parallel on the supply sideso that the line current of the arrangement is in the range of 16-75 A, then this arrangement conforms to IEC 61000-3-12provided that the short-circuit power Ssc at the connection pointof the customer system to the public power system is greaterthan or equal to 120 times the rated output of the arrangement.It is the responsibility of the installation engineer or operator/owner of the device to ensure, if necessary after consultationwith the network operator, that this device is only connected toa connection point with a Ssc value that is greater than or equalto 120 times the rated output of the arrangement.4. CONNECTION AND STARTUP4.1 Mechanical connectionCAUTIONCutting and crushing hazard when removing devicefrom packagingBlades can bend→ Carefully remove the device from its packaging, by the fanhousing. Strictly avoid shocks.→ Wear safety shoes and cut-resistant safety gloves.CAUTIONHeavy load when unpacking deviceRisk of physical injury, such as back injuries.→ Two people should work together to remove the device fromits packaging.; Check the device for transport damage. Damaged devices are not tobe installed.; Install the undamaged device in accordance with your application.CAUTIONPossible damage to the deviceIf the device slips during installation, serious damage can result.→ Ensure that the device is securely positioned at its place ofinstallation until all fastening screws have been tightened.4.2 Electrical connectionDANGERVoltage on the deviceElectric shock→ Always connect a protective earth first.→ Check the protective earth.DANGERFaulty insulationRisk of fatal injury from electric shock→ Use only cables that meet the specified installationregulations for voltage, current, insulation material, capacity,etc.→ Route cables so that they cannot be touched by anyrotating parts.DANGERElectrical charge (>50 μC) between phase conductor andprotective earth connection after switching off supplywith multiple devices connected in parallel.Electric shock, risk of injury→ Ensure sufficient protection against accidental contact.Before working on the electrical hookup, short the supplyand PE connections.CAUTIONVoltageThe fan is a built-in component and has no disconnecting switch.→ Only connect the fan to circuits that can be switched off withan all-pole disconnection switch.→ When working on the fan, secure the system/machine inwhich the fan is installed so as to prevent it from beingswitched back on.Item no. 50348-5-9970 · ENU · Change 89187 · Approved 2016-04-15 · Page 6 / 12ebm-papst Mulfingen GmbH & Co.
