Operating instructionsS4D450-GA14-01Translation of the original operating instructions4. CONNECTION AND START-UP4.1 Connecting the mechanical systemCAUTIONCutting and crushing hazard when removing the fanfrom the packaging→ Carefully remove the device from its packaging, onlytouching the guard grille. Make sure to avoid any shock.→ Wear safety shoes and cut-resistant safety gloves.; Check the device for transport damage. Damaged devices must nolonger be installed.; Install the undamaged device according to your application.4.2 Connecting the electrical systemDANGERElectric voltage on the deviceElectric shock→ Always install a protective earth first.→ Check the protective earth.DANGERIncorrect insulationRisk of fatal injury from electric shock→ Use only cables that meet the specified installationrequirements for voltage, current, insulation material, load etc.→ Route cables such that they cannot be touched by anyrotating parts.DANGERElectrical load (>50 μC) between mains wire andprotective earth connection after switching of the supplywhen switching multiple devices in parallel.Electric shock, risk of injury→ Make sure that sufficient protection against accidental contactis provided.Before working on the electrical connection, theconnections to the mains supply and PE must be shorted.CAUTIONElectrical voltageThe fan is a built-in component and features no electricallyisolating switch.→ Only connect the fan to circuits that can be switched off withan all-pole separating switch.→ When working on the fan, you must switch off theinstallation/machine in which the fan is installed and secure itfrom being switched on again.NOTEWater penetration into leads or wiresWater enters at the cable end on the customers side and candamage the device.→ Make sure that the cable end is connected in a dryenvironment.Connect the device only to circuits that can be switched offusing an all-pole disconnecting switch.4.2.1 Prerequisites; Check whether the data on the type plate agree with the connectiondata.; Before connecting the device, ensure that the supply voltage matchesthe 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 inaccordance with EN 61800-5-1. The protective earth must have across-section equal to or greater than the outer conductor cross-section.We recommend the use of 105°C cables. Ensure that the minimumcable cross-section is at leastAWG26/0.13 mm².4.2.2 Residual current operated deviceOnly pulse-current sensitive and/or universal RCD protectivedevices (Type A or B) are permitted. Like frequency inverters,RCD protective devices cannot provide personal safety whileoperating the device.4.2.3 Voltage controlWith open loop speed control using transformers or electronicvoltage regulators (e.g. phase angle control), excessive currentmay occur.In addition, noises can occur with phase angle controldepending on the mounting situation.4.2.4 Frequency inverterPlease use a frequency converter only after consultation with ebm-papst.When a frequency converter is used for speed adjustment, themaximum safe operating speed (see 3.2 Nominal data) may not beexceeded.Fit sinusoidal filters that work on all poles (live-live and live-earth) between the frequency inverter and the motor foroperation with frequency inverters.Depending on how the device is installed, noises may occur.Heating of the motor due to use of a frequency converter must bechecked in the application by the customer.4.3 Connection in terminal box4.3.1 Preparing connection lines for the connectionStrip the cable just enough so that the screwed cable gland is tight andthe terminals are relieved of strain. Tightening torque, see chapter 3.1Product drawing.Item no. 10876-5-9970 · Revision 82546 · Release 2014-05-08 · Page 6 / 10ebm-papst Mulfingen GmbH & Co.
