WARNING Flying parts Missing safety devices may cause fan blades to be ejected at high speeds, causing bodily harm. → Do not touch the rotor and impeller once they are installed. → Take appropriate safety measures. The safety devices must prevent contact with rotating parts and the printed circuit board. CAUTION If control voltage is applied or a speed setpoint is stored, the motor automatically restarts, e.g. after a power failure. Danger of injury → Keep out of the danger zone of the device. → When working on the device, switch off the mains supply voltage and secure the latter from being switched on again. → Wait until the device stops. → After working on the device, remove any used tools or other objects from the device. 1.5 Safety and protective functions DANGER Missing safety device and non-functioning safety device If there is no safety device, you could be seriously injured, for example by reaching into the running device with your hands. → Operate the device only with a fixed and isolating safety protection and a fixed guard grille. The guard must withstand the kinetic energy of a fan blade detaching at maximum speed. → The device is a built-in component. You, the owner/ operator, are responsible for providing adequate protection for the device. Translation of the original operating instructions → Shut down the device immediately if you detect a missing or ineffective protective feature. 1.8 Deflagration DANGER Gas escapes through leaky housing after deflagration Danger of injury → After a deflagration, check that the housing of the gas blower is tightly sealed. → Replace any gas blower with a leaky housing. DANGER Fire and deflagration hazard The gas blower is not approved according to Ex protection guidelines. Rotating parts can scrape against stationary parts. This may cause sparks and chips. The surface temperature may rise, resulting in a fire. → Check which hazards arise from installing, operating, servicing or disposing the gas blower in conjunction with your device. Prevent these hazards. Carry out all appropriate measures to this purpose. 1.9 Emission WARNING Depending on the installation and operating conditions, a sound pressure level greater than 70 dB(A) may arise. Danger of noise-induced hearing loss 1.6 Electromagnetic radiation → Take appropriate technical safety measures. Interference from electromagnetic radiation is possible, e.g. in conjunction with open and closed-loop control devices. If unacceptable emission intensities occur when the fan is installed, appropriate shielding measures have to be taken by the user. → Protect operating personnel with appropriate safety equipment, e.g. hearing protection. NOTE Electrical or electromagnetic interferences after integrating the device in installations on the customer's side. → Verify that the entire setup is EMC compliant. 1.7 Mechanical movement DANGER Danger of injury from open blower Gas escapes. When the blower is open, you come into contact with rotating and electrically live parts. Escaping gas may also cause explosions. → Never open the blower. → Also observe the requirements of local agencies. 1.10 Hot surface CAUTION High temperature at the electronics enclosure Danger of burn injuries → Ensure that sufficient protection against accidental contact is provided. 1.11 Transport NOTE Transport of blower → Transport the blower in its original packaging only. → Secure the blower so that it does not slip, e.g. by using a clamping strap. WARNING Rotating device Long hair, loose items of clothing and jewellery could become entangled and pulled into the device. You could be injured. → Do not wear any loose clothing or jewellery while working on rotating parts. → Protect long hair by wearing a cap.

CONNECTION AND START-UP 4.1 Connecting the mechanical system DANGER Gas leaking from improperly sealed housing Risk of fatal injury → Connect the device only to circuits that can be switched off using an all-pole disconnecting switch. → When working on the device, you must switch off the system/machine in which the device is installed and secure it from being switched on again. → Prior to commissioning, check that the housing of the gas blower is pressure-tight. When doing so, close the intake and exhaust opening and the shaft opening. NOTE Water penetration into leads or wires Water enters at the cable end on the customers side and can damage the device. → In addition, check that rotating parts do not scrape against stationary parts. DANGER Leaks may occur. As a result of design necessities, the gas blower is not tightly sealed, e.g. at the shaft opening. This may cause leaks during operation. Deflagrations may also cause long-term damage or deformation of the housing, which can result in leaks. An air/ gas mixture may accumulate outside of the gas blower. The blower may explode. You could be severely injured. → Check which hazards arise from installing, operating, servicing or disposing of the gas blower in conjunction with your device. Prevent these hazards. Carry out all appropriate measures to this purpose. CAUTION Cutting and crushing hazard when removing the blower from the packaging → Carefully remove the blower from its packaging, only touching the housing. Make sure to avoid any shock. → Wear safety shoes and cut-resistant safety gloves. ; Check the device for transport damage. Damaged devices must no longer be installed. → Make sure that the cable end is connected in a dry environment. The control voltage circuit is not electrically isolated. Connect the device only to circuits that can be switched off using an allpole 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 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. 4.2.2 Idle current ; Install the undamaged device according to your application. 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. Translation of the original operating instructions 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 ● 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). → 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.
