This also applies for devices which have already been equipped with plugs and terminals or similar connectors by the customer. WARNING Hot motor housing Risk of fire → Ensure that no combustible or flammable materials are located close to the fan. ; Before switching on, check the device for visible external damage and make sure the protective devices are functional. ; Check the fan's air flow paths for foreign matter and remove any foreign matter found. ; Apply the nominal supply voltage. ; Start the device by changing the input signal. NOTE Damage to the device from vibration Bearing damage, shorter service life → Low-vibration operation of the fan must be ensured over the entire speed control range. → Severe vibration can arise for instance from inexpert handling, transportation damage and resultant imbalance or be caused by component or structural resonance. → Speed ranges with excessively high vibration levels and possibly resonant frequencies must be determined in the course of fan commissioning. 5. MAINTENANCE, MALFUNCTIONS, POSSIBLE CAUSES AND REMEDIES Do not perform any repairs on your device. Send the device to ebmpapst for repair or replacement. WARNING Live terminals and connections even with device switched off Electric shock → Wait five minutes after disconnecting the voltage at all poles before opening the device. CAUTION If control voltage or a stored speed set value is applied, the motor will restart automatically, e.g. after a power failure. Risk of injury → Keep out of the device’s danger zone. → When working on the device, switch off the line voltage and ensure that it cannot be switched back on. → Wait until the device comes to a stop. → After working on the device, remove any tools or other objects from the device. If the device is out of use for some time, e.g. when in storage, we recommend switching it on for at least two hours to allow any condensation to evaporate and to move the bearings. Malfunction/fault Impeller not running smoothly Motor not turning → Either run through the resonant range as quickly as possible with speed control or find another remedy. Translation of the original operating instructions → Operation with excessively high vibration levels can lead to premature failure. 4.7 Switching off the device Switching off the device during operation: ; Switch off the device via the control input. ; Do not switch the motor (e.g. in cyclic operation) on and off via power supply. Switching off the device for maintenance: ; Switch off the device via the control input. ; Do not switch the motor (e.g. in cyclic operation) on and off via power supply. ; Disconnect the device from the power supply. Motor/electronics overtemperature Possible cause Imbalance in rotating parts Possible remedy Clean the device; replace it if imbalance persists after cleaning. Make sure no weight clips are removed during cleaning. Mechanical blockage Switch off, isolate from supply and remove mechanical blockage. Line voltage faulty Check line voltage, restore power supply, apply control signal. Faulty connection Isolate from supply, correct connection; see connection diagram.

Abnormal bearing noise At least every 6 months Replace device 5.1 Cleaning 5.3 Disposal To ensure a long service life, check the fans regularly for proper operation and soiling. The frequency of checking is to be adapted accordingly depending on the degree of soiling. For ebm-papst, environmental protection and resource preservation are top priority corporate goals. ebm-papst operates an environmental management system which is certified in accordance with ISO 14001 and rigorously implemented around the world on the basis of German standards. Right from the development stage, ecological design, technical safety and health protection are fixed criteria. The following section contains recommendations for ecological disposal of the product and its components. ; Dirt deposits on the motor housing can cause overheating of the motor. ; Soiling of the impeller can cause vibration that will shorten the service life of the fan. ; Severe vibration can destroy the fan. ; In such cases, switch off the fan immediately and clean it. ; The preferred method of cleaning is dry cleaning, e.g. using compressed air. 5.3.1 Country-specific legal requirements NOTE Country-specific legal requirements Always observe the applicable country-specific legal regulations with regard to the disposal of products or waste occurring in the various phases of the life cycle. The corresponding disposal standards are also to be heeded. ; Do not use aggressive cleaning agents! NOTE Damage to the device during cleaning Malfunction possible → Do not clean the device using a water jet or high-pressure cleaner. → Do not use any acid, alkali or solvent-basedcleaning agents. → Do not use any pointed or sharp-edged objects for cleaning ; Completely remove any cleaning agents used. 5.3.2 Disassembly Disassembly of the product must be performed or supervised by qualified personnel with the appropriate technical knowledge. The product is to be disassembled into suitable components for disposal employing standard procedures for motors. ; If severe corrosion is visible on load-bearing or rotating parts, switch off the device immediately and replace it. WARNING Heavy parts of the product may drop off. Some of the product components are heavy. These components could drop off during disassembly. This can result in fatal or serious injury and material damage. ; Repair of load-bearing or rotating parts is not permitted! ; Operate the fan for 2 hours at maximum speed so that any water that has ingressed can evaporate. ; If cleaning does not eliminate vibrations, the fan may need to be rebalanced. To have it rebalanced, contact ebm-papst. ; The fan is equipped with maintenance-free ball bearings. The lifetime lubrication of the ball bearings is designed for a service life of 40,000 hours. ; If bearing replacement is necessary after that period, contact ebmpapst. Translation of the original operating instructions acoustic ; Adapt the maintenance intervals to the actual level of dust exposure. 5.2 Safety inspection What to check Contact protection cover for intactness or damage Device for damage to blades and housing Fastening the cables Insulation of cables for damage Welds for crack formation How to check How often Visual inspection At least every 6 months What action? Repair or replacement of device Visual inspection At least every 6 months Replacement of device Visual inspection At least every 6 months Visual inspection At least every 6 months Fasten Visual inspection At least every 6 months Replace cables Replace device → Secure components before unfastening to stop them falling. 5.3.3 Component disposal The products are mostly made of steel, copper, aluminum and plastic. Metallic materials are generally considered to be fully recyclable. Separate the components for recycling into the following categories: ● Steel and iron ● Aluminum ● Non-ferrous metal, e.g. motor windings ● Plastics, particularly with brominated flame retardants, in accordance with marking ● Insulating materials ● Cables and wires ● Electronic scrap, e.g. circuit boards Only ferrite magnets and not rare earth magnets are used in external rotor motors from ebm-papst Mulfingen GmbH & Co. KG. ; Ferrite magnets can be disposed of in the same way as normal iron and steel. Electrical insulating materials on the product, in cables and wires are made of similar materials and are therefore to be treated in the same manner. The materials concerned are as follows: ● Miscellaneous insulators used in the terminal box ● Power cables ● Cables for internal wiring ● Electrolytic capacitors Item no. 50339-5-9970 · ENU · Change 259697 · Approved 2022-09-06 · Page 9 / 10 ebm-papst Mulfingen GmbH & Co.
