It is the responsibility of the installation engineer or operator/ owner of the device to ensure, if necessary after consultation with the network operator, that this device is only connected to a connection point with a Ssc value that is greater than or equal to 120 times the rated output of the arrangement. 4. CONNECTION AND START-UP 4.1 Connecting the mechanical system CAUTION Cutting and crushing hazard when removing the fan from the packaging → Carefully remove the device from its packaging, only touching the guard grille. Make sure to avoid any shock. → Wear safety shoes and cut-resistant safety gloves. CAUTION Heavy load when taking out the device Bodily harm, e.g. back injuries, are possible. → Two people should remove the device out of its packaging together. ; Check the device for transport damage. Damaged devices must no longer be installed. ; Install the undamaged device according to your application. 4.2 Connecting the electrical system DANGER Electric voltage on the device Electric shock → Always install a protective earth first. → Check the protective earth. DANGER Incorrect insulation Risk of fatal injury from electric shock → Use only cables that meet the specified installation requirements for voltage, current, insulation material, load etc. → Route cables such that they cannot be touched by any rotating parts. DANGER Electrical load (>50 µC) between mains wire and protective earth connection after switching of the supply when switching multiple devices in parallel. Electric shock, risk of injury Translation of the original operating instructions → Make sure that sufficient protection against accidental contact is provided. Before working on the electrical connection, the connections to the mains supply and PE must be shorted. CAUTION Electrical voltage The fan is a built-in component and features no electrically isolating switch. → Only connect the fan to circuits that can be switched off with an all-pole separating switch. → When working on the fan, you must switch off the installation/machine in which the fan is installed and secure it from being switched on again. NOTE Interferences and failures are possible Maintain a distance to the power supply line when routing the control lines of the device. → Ensure a sufficiently large clearance. Recommendation: clearance > 10 cm (separate cable routing) Item no. 50344-5-9970 · Revision 68161 · Release 2009-09-09 · Page 6 / 12 ebm-papst Mulfingen GmbH & Co.

Connect the device only to circuits that can be switched off using an all-pole disconnecting switch. 4.2.1 Prerequisites ; Check whether the data on the type plate agree with the connection data. ; Before connecting the device, ensure that the supply voltage matches the operating voltage of the device. Only universal (type B or B+) RCD protective devices are permitted. Like frequency inverters, RCD protective devices cannot provide personal safety while operating the device. When switching on the power supply of the device, pulsed charge currents from the capacitors in the integrated EMC filter can lead to the RCD protective devices triggering without delay. We recommend residual current devices with a trigger threshold of 300 mA and delayed triggering (super-resistant, characteristic K). 4.2.5 Leakage current For asymmetrical power systems or if a phase fails, the leakage current can increase to a multiple of the nominal value. ; Only use cables designed for current according to the type plate. For determining the cross-section, follow the basic principles in accordance with EN 61800-5-1. The protective earth must have a cross-section equal to or greater than the outer conductor crosssection. We recommend the use of 105°C cables. Ensure that the minimum cable cross-section is at least AWG26/0.13 mm². 4.2.6 Locked-rotor protection 4.2.2 Power supply connection, fuse protection Strip the cable just enough so that the screwed cable gland is tight and the terminals are relieved of strain. Tightening torque, see chapter 3.1 Product drawing. Assignment of conductor cross-sections and the fuse protection required for them (overload protection only, no device protection).

Remove the cap only in those places where cables are inserted. ; Mount the screwed cable glands with the seal inserts provided in the terminal box. ; Insert the line(s) (not included in the standard scope of delivery) into the terminal box. ; First connect the "PE" (protective earth) connection. ; Connect the lines to the corresponding terminals. Use a screwdriver to do so. During the connection work, ensure that no cables splice off. Item no. 50344-5-9970 · Revision 68161 · Release 2009-09-09 · Page 7 / 12 ebm-papst Mulfingen GmbH & Co.
