CONNECTION AND START-UP 4.1 Connecting the mechanical system CAUTION Cutting and crushing hazard when removing the fan from the packaging 4.2.1 Prerequisites ; Check whether the data on the type plate agree with the connection data. → Carefully remove the fan from its packaging. Make sure to avoid any shock. ; Before connecting the device, ensure that the supply voltage matches the operating voltage of the device. → Wear safety shoes and cut-resistant safety gloves. ; 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. ; 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. Earth wire contact resistance to EN 61800-5-1 Compliance with the impedance specifications to EN 61800-5-1 for the protective earth circuit must be verified in the end application. Depending on the installation situation, it may be necessary to install an additional protective earthing conductor via the additional protective earth connection point available on the device. The protective earth connection point is located on the housing and has a protective earth symbol and a bore hole. 4.2.2 Idle current → 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 Water penetration into leads or wires Water enters at the cable end on the customers side and can damage the device. Because of the EMC filter integrated for compliance with EMC limits (interference emission and interference immunity), idle currents in the mains cable can be measured even when the motor is at a standstill and the mains voltage is switched on. ● The values lie in a range of typical < 250 mA. ● The effective power in this operating state (readiness for operation) is simultaneously at typical < 4 W. 4.2.3 Residual current operated device Only pulse-current sensitive and/or universal RCD protective devices (Type A or B) 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). 4.2.4 Locked-rotor protection Due to the locked-rotor protection, the start-up current (LRA) is equal to or less than the nominal current (FLA). → Make sure that the cable end is connected in a dry environment.

If the device remains out of use for some time, e.g. when in storage, we recommend switching the device on for at least two hours to allow any condensate to evaporate and to move the bearings. Translation of the original operating instructions Malfunction/error Impeller running roughly Motor does not turn Possible cause Imbalance in rotating parts Mechanical blockage Mains supply voltage faulty Faulty connection Thermal overload protector responded Possible remedy Clean the device; if imbalance is still evident after cleaning, replace the device. If you have attached any weight clips during cleaning, make sure to remove them afterwards. Switch off, deenergise, and remove mechanical blockage. Check mains supply voltage, restore power supply, apply control signal. De-energise, correct connection, see connection diagram. Allow motor to cool off, locate and rectify cause of error, if necessary cancel restart lock-out Improve cooling. Let the device cool down. To reset the error message, switch off the mains supply voltage for a min. of 25 s and switch it on again. Reduce the ambient temperature. Reset by reducing control input to 0.
