CONNECTION AND STARTUP 4.1 Mechanical connection DANGER Gas leaking from poorly sealed housing Risk of fatal injury → Prior to startup, verify whether the gas blower's housing is pressure-tight. When doing so, seal off the intake and outlet openings as well as the shaft opening. → In addition, verify that no rotating parts scrape against stationary parts. DANGER Leaks may occur. Due to its design, the gas blower is not tightly sealed, e.g. at the shaft opening. This may result in 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 can explode. Severe injuries can result. → Check which hazards arise from installing, operating, servicing or disposing of the gas blower in conjunction with your device. Avoid any such hazards. Carry out all necessary measures. CAUTION Cutting and crushing hazard when removing blower from packaging → Carefully remove the blower from its packaging, touching only the housing. Strictly avoid shocks. → Wear safety shoes and cut-resistant safety gloves. CAUTION Heavy load when unpacking device Risk of physical injury, such as back injuries. → Two people should work together to remove the device from its packaging. Translation of the original operating instructions ; Check the device for transport damage. Damaged devices are not to be installed. ; Install the undamaged device in accordance with your application. CAUTION Possible damage to the device If the device slips during installation, serious damage can result. → Ensure that the device is securely positioned at its place of installation until all fastening screws have been tightened. 4.2 Electrical connection DANGER Voltage on the device Electric shock → Always connect a protective earth first. → Check the protective earth.

DANGER Electrical charge (>50 µC) between phase conductor and protective earth connection after switching off supply with multiple devices connected in parallel. Electric shock, risk of injury → Ensure sufficient protection against accidental contact. Before working on the electrical hookup, short the supply and PE connections. 4.2.2 Supply connection and fuses Assignment of supply cable cross-sections and their required fuses (line protection only, no equipment protection). Nominal voltage 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC 3/PE AC 380-480 VAC VDE 16 A UL 15 A Automatic circuit breaker VDE C16A 20 A 20 A C20A 2.5 14 25 A 25 A C25A 4.0 12 32 A 30 A C32A 6.0 10 CAUTION Voltage The device is a built-in component and has no disconnecting switch. * AWG = American Wire Gauge → Only connect the device to circuits that can be switched off with an all-pole disconnection switch. 4.2.3 Reactive currents NOTE Device malfunctions possible Route the device's control lines separately from the supply line. → Maintain the greatest possible clearance. Recommendation: clearance > 10 cm (separate cable routing) NOTE Water ingress into wires or cables Water ingress at the customer end of the cable can damage the device. → Make sure the end of the cable is connected in a dry environment. The control voltage circuit is not electrically isolated. Only connect the device to circuits that can be switched off with an all-pole disconnection switch. 4.2.1 Requirements ; Check whether the data on the nameplate match the connection data. ; Before connecting the device, make sure the power supply matches the device voltage. ; Only use cables designed for the current level indicated on the nameplate. For determining the cross-section, note the sizing criteria according to EN 61800-5-1. The protective earth must have a cross-section equal to or greater than that of the phase conductor. We recommend the use of 105 °C cables. Ensure that the minimum cable cross-section is at least AWG 26 / 0.13 mm². Cable crosssection mm² 1.5 Cable crosssection *AWG 16 Because of the EMC filter integrated for compliance with EMC limits (interference emission and immunity to interference), reactive currents can be measured in the supply line even when the motor is at a standstill and the line voltage is switched on. → When working on the device, secure the system/ machine in which the device is installed so as to prevent it from being switched back on. Translation of the original operating instructions Fuse ● The values are typically less than 250 mA. ● At the same time, the effective power in this operating state (operational readiness) is typically < 5 W. 4.2.4 Residual current circuit breaker (RCCB) Only universal residual current devices (type B or B+) are allowed. As with variable frequency drives, residual current devices cannot provide personal safety while operating the device. When the device's power supply is switched on, pulsed charging currents from the capacitors in the integrated EMC filter can lead to the residual current devices tripping without delay. We recommend the use of residual current circuit breakers with a trip threshold of 300 mA and delayed tripping (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. 4.2.6 Locked-rotor protection Due to the locked-rotor protection, the starting current (LRA) is equal to or less than the nominal current (FLA).
