3.5 Installation

3.5.1 Machine designMachines of this series are self-ventilated low-voltage three-phase asynchronous drives witha cylindrical shaft end and featherkey way. They can be supplied as single-speed machineswith different efficiency classes or as pole changing machines for several speeds.

In the case of machines with feet (IM B3 type of construction), the feet are cast or bolted on.

The position of the feet bolted onto the housing of the machine can be changed, e.g. in orderto change the position of the terminal box, but this must only be done by authorized partners.The surfaces on which the feet rested must then be evened out and made parallel with themachine shaft, if necessary by placing shims underneath the machine. Any damagedpaintwork must be correctly repaired.

3.5.2 RegulationsOverview

3.5.3 Cooling and ventilation3.5.3.1 General

The machines of this series are three-phase asynchronous machines with a closed primary(internal) cooling circuit and an open secondary cooling circuit (surface cooling). The form ofsurface cooling can vary depending on the type of cooling provided:

3.5.3.2 Machines with a fan

Self-ventilation (standard): Type of cooling IC 411 in accordance with IEC / EN 60034-6Located at the ND end of the stator housing is an air intake cowl that guides the external airon its way to the motor. The external air is drawn in through openings in the air intake cowland flows axially across the outer cooling ribs of the motor frame. The fan wheel responsiblefor the external flow of cool air is fastened to the machine shaft.The fan wheels are independent of the direction of rotation.In the case of frequent switching or braking or if the speed is controlled continually below thenominal speed, the cooling effect must be checked.

Machines for use in Zone 21 and Zone 22 have a metal fan.

Forced ventilation (optional): Type of cooling IC 416 in accordance with IEC / EN 60034-6Cooling independent of the speed is achieved by means of a separately driven fan wheel

(forced ventilation). Forced ventilation is independent of the operating state of the machine. Itmust be ensured that the machine is not operated without starting the external fan.The fan wheel for the external flow of cold air is powered by an independent module and isenclosed by the fan cowl.

3.5.4 BearingsIn order to support the machine shaft and maintain its position in the non-moving part of themachine, only 2 rolling-contact bearings are used. One rolling-contact bearing performs thefunction of a location bearing which transfers axial and radial forces from the rotatablemachine shaft to the non-moving part of the machine. The second rolling-contact bearing is afloating/guide bearing in order to allow thermal expansion inside the machine and transferradial forces.The nominal (calculated) useful life of the bearings (ISO 281) is 20,000 hours if thepermissible radial/axial forces are fully utilized. However, the achievable useful life of thebearings can be considerably longer in the case of smaller forces (e.g. coupling mode).

The rolling-contact bearings are lubricated for life (standard feature) and therefore do notrequire maintenance.

If the option for re-lubrication is taken up, the information on the rating plate must becomplied with.

3.5.5 BalancingThe machines are balanced dynamically with a half featherkey (code "H") in accordance withISO 8821.The balancing quality corresponds to vibration severity grade "A" for the complete machine;vibration severity grade "B" is possible as an option.

CAUTIONDuring transport, all the lifting eyes on the machine are to be used and any eyes which arescrewed in must be firmly tightened. They are designed to bear the weight of the machine

alone and therefore no additional loads should be added. Eyebolts are to be screwed inright up to their supporting surface. If necessary, use suitable rated transport materials suchas lifting straps (EN 1492-1) and lashing straps (EN12195-2).

Suspended transportWARNING

Use suitable means of conveyance for transport and during installation. If several items oftransport material are used for fastening, two straps must be able to carry the whole load.

Secure lifting materials to make sure they cannot slip!

Remove any transport locks before start-up and either keep them in a safe place or unlockthem. You can then use them again for transporting further items or you can apply themagain.

The machines are packed in different ways depending on how they are transported and theirsize. Unless agreed otherwise in the contract, the packaging is in accordance with thepacking guidelines of ISPM (International Standards for Phytosanitary Measures).

4.4 Electromagnetic compatibility

1LA5/6/7/9, 1LP7/9, 1PP6/7/9, 1MA6/7, 1MF6/7, 1MJ6, 1LE1


4.4 Electromagnetic compatibilityWhen used in accordance with their intended purpose and operated in an electrical supply

system with characteristics to EN 50160, the enclosed motors (IP 55 and higher) comply withthe requirements of the EC Directive concerning electromagnetic compatibility 89/336/EEC.

NOTICEIf the torque levels are very unequal (e.g. when a reciprocating compressor is being driven),a non-sinusoidal machine current will be induced whose harmonics can bring about anexcessive reaction on the supply system and so cause excessive emitted interference.

NOTICEIf operated with a frequency converter, the emitted interference varies in strength,

depending on the design of the converter (type, interference suppression measures,manufacturer). In order to prevent exceeding of the limit values stipulated by EN 50081 forthe drive system, consisting of machine and converter, the EMC instructions specified bythe converter manufacturer must be strictly observed. If the manufacturer recommends thatthe cable leading to the machine be shielded, the shield is most effective if it is conductivelyconnected over a large surface area to the metal terminal box of the machine (with metalscrew-type connections).In the case of machines with built-in sensors (e.g. PTC thermistors), interference voltagesresulting from the converter can occur and affect the sensor cable.

Immunity to interferenceThe machines fulfil the requirements of interference immunity in conformity with EN 50082. Ifmachines with integrated sensors (e.g. PTC thermistors) are used, the operator himself mustensure sufficient interference immunity by selecting a suitable sensor signal lead (possiblewith shielding, connected in the same way as supply cable leading to machine) and asuitable evaluation unit.If the machines are operated with a converter at higher speeds than the rated speed, themechanical speed limits (safe operating speed IEC / EN 60034-1) are to be complied with.

4.5 DisposalMachines must be disposed of carefully taking into account national and local regulations in

the normal recycling process or by returning the machines to the manufacturer.

The following must be taken into account when disposing of a machine:

Oil and grease in accordance with the directive on used oil. No mixing with solvents,cleaner solvents or paint residues

For the purposes of recycling, the components must be separated into:- electronic scrap (encoder electronics)- scrap iron- aluminum- non-ferrous heavy metal (machine windings, worm gears)- plastic (polyamide, glass-fiber reinforced polyamide, polypropylene)

5.1.3 BalancingThe rotors are balanced dynamically. The balancing quality corresponds to vibration severity

grade "A" for the complete machine as standard. The optional vibration severity grade "B" isindicated on the rating plate.

The declaration regarding the type of featherkey for balancing is marked on the face of theshaft end and on the rating plate.

Designation: As a standard measure, balancing is carried out dynamically with a half featherkey (code

"H") in accordance with ISO 8821.

"F" means balancing with a whole featherkey (optional version). "N" means balancing without a featherkey (optional version).The featherkey declaration on the shaft and transmission element must indicate the correcttype of balancing in each case and must be correctly mounted.The balancing quality corresponds to vibration severity grade "A" for the complete machine;vibration severity grade "B" is possible as an option, i.e. in order to ensure the desiredbalancing quality, it must be ensured that the featherkey declarations on the hub andmachine shaft complement each other in the case of a shorter or longer transmissionelement.

NoteThe permissible vibration levels in line with the evaluation zones according to ISO 10816determine whether mounting and balancing have been carried out correctly. If the coupledmachine does not comply with the vibration level according to EN 10816, complete dynamicbalancing or an alteration to the foundations may be necessary.

CAUTIONIt is permissible to push on or pull off transmission elements only with suitable equipment.The featherkeys are to be secured during transprot to prevent them falling out.The generally required measures for touch protection of the transmission elements are tobe observed.

5.1.4 Noise emissionNOTICEWhen the noise that is emitted at workplaces of the personnel responsible for operating theequipment is assessed, it must be borne in mind that the A-weighted sound pressure level,measured in accordance with ISO 1680, namely 70 dB(A), is not exceeded if the three-phase machines are operated with the rated output.


5.2.1 General measuresMake sure that the machine is level and ensure secure fastening of feet and flanges, precisealignment in the case of direct coupling, and also cleanliness of the fastening surfaces. Avoidinstallation-related resonances with the rotating frequency and double line frequency. Turnrotor by hand and pay attention to any unusual noises. Check the direction of rotation withthe motor uncoupled.

NOTICEAny paint damage that occurs when the machine is being aligned and fastened is to be

immediately repaired in a technically appropriate manner.

MeasuresThe following measures are required in order to compensate any radial offset at the couplingand to horizontally adjust the electrical machine with respect to the driven load:

Vertical positioningPlace shims under the machine feet to position it vertically and to preventstress/distortion. The number of shims should be kept as low as possible, i.e. stack asfew as possible.

Horizontal positioningTo position the machine horizontally, push it sideways on the foundations and ensure thatthe axial position is maintained (angularity error).

When positioning the motor, ensure that there is a uniform axial gap around the coupling. Smooth running

Stable, vibration-free design of the foundations in accordance with DIN 4024 and precisealignment of the coupling, as well as a well-balanced transmission element (coupling, beltpulleys, fans, etc.), are prerequisites for smooth running with low vibration.

Complete balancing of the machine with the transmission element may be necessary.For details and evaluation criteria, see ISO 10816.

5.3 Connecting

5.3.1 Connection of the machine5.3.1.1 Electrical connection

WARNINGAny work on the stationary machine must be performed by qualified personnel, with themachine isolated from the supply and secured so that it cannot be switched back on again.This also applies to auxiliary circuits (e.g. anti-condensation heater). Check for isolation

from supply!If the incoming power supply system displays any deviations from the rated values in termsof voltage, frequency, curve form or symmetry, such deviations will magnify the increase intemperature and influence electromagnetic compatibility.Before starting work, make sure that a protective conductor is securely connected.

The stipulations in IEC / EN 60034-1 (VDE 0530-1) regarding operation at the limits of the Azones (5% voltage difference or 2% frequency difference) and the B zones, especially inrespect of temperature increase and deviation of the operating data from the rated data onthe rating plate, are to be complied with. Under no circumstances may the limits beexceeded.

WARNINGMains with non-grounded neutral pointOperating the machine on a mains with a non-grounded neutral point is only permittedduring rarely occurring, short time intervals, e.g. until elimination of an error (ground fault ofa cable, EN 60034-1).

The connection must be made in such a way that a permanently safe electrical connection isguaranteed (no protruding wire ends); use the assigned cable-end fittings (e.g. cable lugs,end sleeves).Connect the supply voltage and arrange the jumpers according to the circuit diagram in theterminal box.

Select the connecting cables in accordance with DIN VDE 0100 and in accordance with therated current and the installation-specific conditions (e.g. ambient temperature, routingmethod etc. according to DIN VDE 0298 or IEC/EN 60204-1).

The necessary connection data regarding

the direction of rotation, the number and arrangement of the terminal boxes, the circuit and connection of the machine winding,are defined in the "Technical specifications".

The following features make this type of electrical connection different from that forstandard machines:

Area A in IEC/EN 60034-1 (VDE 0530-1) (5% voltage or 2% frequencydeviation, curve, supply symmetry) must be maintained so that the temperaturerise remains within the permissible limits.

Larger deviations from the rated data may result in electrical machines heatingup to impermissible levels. This information must be specified on the ratingplate. Under no circumstances may the limits be exceeded.

Any machine with type of protection Increased Safety "e" must be protectedagainst overheating in accordance with EN 60079-14 using an inverse-timedelay circuit-breaker with phase loss protection and asymmetry detection to EN60947, or using an equivalent device in all phases.

In the case of machines with type of protection Increased Safety "e", theovercurrent device with an inverse-time delay tripping mechanism should beselected so that the time to disengagement (taken from the characteristic of theswitch for the IA/Nratio of the machine to be protected) is no greater than themachine heating time tE. The IA/INratio and the heating time tEshould be takenfrom the rating plate. The protective device should also be set to the ratedcurrent. A tripping device that conforms to RL94/9/EC should be used.

As regards machines with type of protection Increased Safety "e", in the eventof a locked rotor the protective device must disconnect within the tEtimespecified for the relevant temperature class. In accordance with thespecifications of the EC-type examination certificate, electrical machines usedfor heavy starting (ramp-up time > 1.7 x tEtime) should be protected by startupmonitoring.Direct monitoring of the winding temperature is permissible as a means of

thermal machine protection, provided that this is certified and specified on therating plate.

With pole-changing machines, separate, interlocked protective devices arerequired for each speed step. Devices with an EC-type examination certificateare recommended.

5.3.1.2 Terminal designationsThe following definitions apply in principle to the terminal designations of three-phasemachines in accordance with DIN VDE 0530 Part 8 or IEC 60034-8:

Table 5- 2 Terminal designations (with the 1U1-1 as an example)

1 U 1 - 1 Designationx Index showing the pole assignment for pole-changing machines (where

5.3.1.3 Direction of rotationThe standard motors are suitable for clockwise and counter-clockwise rotation.

Connection of the power cables in the phase sequence L1, L2, L3 to U, V, W results inclockwise rotation (looking at the DE shaft end on the drive side). If two of the connectionsare swapped, then the resulting direction of rotation is counter-clockwise (e.g. L1, L2, L3 toV, U, W).In the case of machines intended for only one direction of rotation, the prescribed direction ofrotation is marked by a direction arrow on the machine.

5.3.1.4 Connection with/without cable lugsIn the case of terminals with terminal clips, the conductors are to be spread out in such away that the terminating heights on both sides of the web are about the same. This methodof connection requires that a single conductor must be bent into a U shape or is to be

connected with a cable lug. The same applies to the inner and outer terminals of the groundconductor

When using cable lugs to make the connection, the choice of cable lug size must match therequired conductor cross-section and the bolt size. A skewed arrangement is onlypermissible if the required air gaps and creepage distances are adhered to.Strip the insulation from conductor ends in such a way that the remaining insulation almostreaches the cable lug.

NoteThe direct contact between the cable lug surfaces and the contact nuts ensure that theconnection can carry current.

5.3.1.5 Connecting protruding cablesIn the case of connection cables protruding out of the machine, no terminal board is installedon the terminal base of the machine housing. The connection cables are directly connectedto stator winding terminals at the factory.

The connection cables are color coded or labeled and are provided with end sleeves by thecustomer. The customer directly connects individual cables in the control cabinet for theirsystem in accordance with the labeling.

5.3.5 Connection to the converterCAUTION

The standard insulating system is suitable for converter voltages up to 460 V. For highervoltages, a special insulating system must be used or special measures must be taken, e.g.an output filter.

NoteEMCComply with the instructions given in the section regarding electromagnetic compatibility.

See list of additional operating instructions in appendix

Where machines with type of protection Increased Safety "e" are concerned,connection to a converter must be expressly certified. The separate manufacturernotes must be observed. For type of protection Increased Safety "e", the machine,converter and protective devices must be labeled as working in conjunction withone another, and the permitted operating data must be specified in the devices'collective EC-type examination certificate.

Machines connected to a converter for Zone 21 and Zone 22 are generally fittedwith 3 PTC thermistors in accordance with DIN 44082 with a rated interventiontemperature that depends on the maximum possible surface temperature. PTCthermistor evaluators should be selected for conformity to this standard. Themaximum temperature at the cable entries is 120C. Appropriate cables for this

temperature must be used. The maximum frequency, which is dependent on thenumber of poles, is stamped on the rating plate and must not be exceeded. Incases where the system linking the converter, cable and electrical machine drawsits power from a public grid with an operating voltage of up to 690 V, the maximumvalue of the transients at the end of the cable must not be more than twice the DClink voltage of the converter (approx. 2 kV).Machines with flameproof enclosure "d" or "de" protection are equipped with threetemperature sensors inserted in the windings and one temperature sensor in thegland plate to ensure that the temperature class is maintained. The temperaturesensors are to be connected in series according to the circuit diagram.Machines with temperature sensors for warning and tripping each have threetemperature sensors in the winding and one temperature sensor in the gland plate.

Temperature sensors are to be connected in series in according to the circuitdiagram.

Commissioning 66.1 Checking the insulation resistanceSafety information

WARNINGOnly expert personnel should be entrusted with work on power installations.

All covers which are designed to prevent active or rotating parts from being touched, orwhich are necessary to ensure correct air guidance and thus effective cooling, must beinstalled prior to start-up.

Checking the insulation resistanceCAUTIONThe insulation resistance needs to be checked prior to start-up and again after anyextended periods of storage or periods during which the equipment is not in operation.Before you begin measuring the insulation resistance, please read the manual for theinsulation resistance meter you are going to use. Any cables of the main circuit which arealready connected should be disconnected from the terminals in order to carry out theinsulation measurements.

WARNINGDuring the measurement, and immediately afterwards, some of the terminals are athazardous voltage levels and must not be touched. Carry out a check with the powercables connected that no voltage can be applied.

Measure the minimum insulation resistance of the winding to the machine housing, ifpossible at a winding temperature between 20 and 30C. Different insulation resistancevalues apply at other temperatures. When making the measurement, you must wait until thefinal resistance value is reached (approx. 1 minute).

The critical insulation resistance is reached at the operating temperature of the winding.
