Operating instructionsM3G150-NA02-52Translation of the original operating instructions4. CONNECTION AND START-UP4.1 Connecting the mechanical systemWARNINGHot motor housingFire hazard→ Ensure that no combustible or flammable materials arelocated close to the motor.CAUTIONCutting and crushing hazard when removing the motorfrom the packaging→ Carefully remove the device from its packaging. Make sureto avoid any shock.→ Wear safety shoes and cut-resistant safety gloves.CAUTIONHeavy load when taking out the deviceBodily harm, e.g. back injuries, are possible.→ Two people should remove the device out of its packagingtogether.; 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 motor is a built-in component and features no electricallyisolating switch.→ Only connect the motor to circuits that can be switched offwith an all-pole separating switch.→ When working on the motor, you must switch off thesystem/machine in which the motor is installed and secure itfrom 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 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.Earth wire contact resistance to EN 61800-5-1Compliance with the impedance specifications to EN 61800-5-1 for theprotective earth circuit must be verified in the end application.Depending on the installation situation, it may be necessary to install anadditional protective earthing conductor via the additional protective earthconnection point available on the device.The protective earth connection point is located on the housing and hasa protective earth symbol and a bore hole.4.2.2 Power supply connection, fuse protectionAssignment of conductor cross-sections and the fuse protection requiredfor them (overload protection only, no device protection).NominalvoltageSafetyfuseAutomaticcircuitbreakerWirecross-sectionWirecross-sectionVDE UL VDE mm² *AWG3/PE AC380 - 480VAC16 A 15 A C16A 1.5 163/PE AC380 - 480VAC20 A 20 A C20A 2.5 143/PE AC380 - 480VAC25 A 25 A C25A 4.0 123/PE AC380 - 480VAC32 A 30 A C32A 6.0 10* AWG = American Wire GaugeItem no. 50851-5-9970 · ENG · Revision 78381 · Release 2012-09-12 · Page 6 / 12ebm-papst Mulfingen GmbH & Co.
