Operating instructionsD3G180-AB62-01Translation of the original operating instructions4. CONNECTION AND START-UP4.1 Connecting the mechanical systemCAUTIONCutting and crushing hazard when removing blowerfrom packaging→ Carefully remove the blower from its packaging by graspinghold of the housing. Never subject to impact.→ Wear safety shoes and cut-resistant safety gloves.NOTEDamage to device from vibrationBearing damage, reduced service life→ Forces or impermissibly high vibration levels must not betransmitted to the fan from system components.→ If the fan is connected to air ducts, it should isolated fromvibrations, for example using compensators or similarelements.→ Fasten the fan to the substructure without distorting it.; Check the device for transport damage. Damaged devices must nolonger be installed.; Install the undamaged device according to your application.CAUTIONPossibility of damage to the deviceSerious damage may result if the device slips during assembly.→ Keep the device fixed in position at the installation locationuntil all attachment screws have been tightened.● The fan must not be strained on fastening.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 device is a built-in component and features no electricallyisolating switch.→ Connect the device only to circuits that can be switched offusing an all-pole disconnecting switch.→ When working on the device, you must switch off thesystem/machine in which the device is installed and secureit from being switched on again.NOTEInterferences and failures are possibleMaintain a distance to the power supply line when routing thecontrol lines of the device.→ Ensure a sufficiently large clearance.Recommendation: clearance > 10 cm (separate cablerouting)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 that the data on the type plate match the connection data.; 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.Protective earth contact resistance as per EN 60335Compliance with the resistance specifications as per EN 60335 for theprotective earth connection circuit must be verified in the application.Depending on the installation situation, it may be necessary to connectan additional protective earth conductor by way of the extra protectiveearth terminal provided on the device.4.2.2 Locked-rotor protectionDue to the locked-rotor protection, the start-up current (LRA) isequal to or less than the nominal current (FLA).4.3 Connection of the cablesExternal leads are brought out of device.; First connect the "PE" (protective earth) connection.● Connect the lines according to your application. When doing so,observe chapter 4.4 Connection screen.Item no. 50035-5-9970 · ENG · Revision 200166 · Release 2019-06-17 · Page 6 / 10ebm-papst Mulfingen GmbH & Co.
