2. Safety and startup notes for low-voltage machinesaccording to Low-Voltage Directive 73/23/EEC

2.1 General

Low-voltage motors have dangerous, live and rotating parts, and probably hot surfaces. All work fortransport, connection, commissioning and maintenance is to be made by qualified, responsiblespecialists (EN50110-1/VDE 0105; IEC 364 must be observed). Negligent conduct can cause serious personal injury and property damage.

2.2 Use in accordance with regulations

These low-voltage machines are intented for industrial installations. They comply with the harmonizedstandards of Series EN 60034 (VDE 0530). The use in hazardous locations is prohibited.

IP 54 Types of enclosure should by no means be used in the open air. Air-cooled designs are rated forambient temperatures from –20°C to +40°C as well as installation altitudes of 1000 m above mean sealevel. Be absolutely sure to observe deviating data on the rating plate. The conditions prevailing atthe installation site must be in compliance with all rating plate data.

Note: Low-voltage machines are components for installation in machines in the intendmentof Machine Directive 98/37/ECC. Startup is not permitted until conformity of the endproduct with this Directive has been established (among others, observe EN 60204-1).

2.3 Handling, storage

Damage ascertained after delivery must be reported to the transport company immediately; ifnecessary, startup must be ruled out. Screwed lifting eyes must be tightened firmly. They aredesigned for the weight of the low-voltage machine; do not attach additional loads. If necessary, usesuitable and amply dimensioned material-handling equipment (e.g. rope guides).

Remove existing transport locks prior to startup. Reuse these for subsequent handling. Iflow-voltage machines are stored, make sure the environment is dry, dust-free and vibration-free(Veff 0,2 mm/s) (bearing damage with motor at standstill). Measure the insulation resistance priorto startup. In the case of values of 1,5 MΩ , dry the windings. Observe ”Storage Instructions”.

2.4 Installation

Ensure a uniform supporting surface, perfect foot and flange attachment and accurate alignment withdirect coupling. Avoid design-related resonances with the rotation frequency and the double mainsfrequency. Turn the rotor by hand and check for abnormal slipping noises. Check direction of rotationin uncoupled condition (observe Section ”Electric Connection”).

Mount and/or remove belt pulleys and couplings only with suitable devices (through heating!) and coverwith a guard against contact. Avoid inadmissible belt tensions (Technical List).The balancing condition of the low-voltage machine is indicated in the parallel keyway (H = half, F = whole keyway). In the case of a design with a half keyway (H), the coupling must likewisebe balanced with a half keyway. Remove any projecting, visible keyway portion by machining.

Establish any necessary pipe connections. Instruct the Owner to provide a covering for mounting typeswith shaft end towards the top to prevent foreign matter from falling into the fan. Aeration must not beobstructed, and the exhaust air - including that of adjacent units - must not be directly taken in again.

Figure 2.4: Ventilation

BA MC295 EN 07.976 / 23

2.5 Electrical connection

All work must only be carried out by qualified specialized staff with the low-voltage machine releasedand protected against restarting. This also applies to auxiliary circuits (e.g. anticondensation heater).Check for any residual voltages.

Exceeding the tolerances specified in EN 60034-1 (VDE 0530, Part 1)- voltage 5%, frequency 2%, curvature, symmetry - will increase through heating and affect the electromagnetic compatibility. Observe the rating plate dataas well as the connection diagram in the terminal box.

The connection must be made in such a manner that a permanently safe electric link is maintained(no projecting wire ends); use allocated cable end protection. Make a safe ground wire connection.

The smallest clearances between bare, live parts among themselves and against earth must not be lessthan the values given in DIN VDE 0110-1:8mm at UN 550V, 10mm at UN 725V, 14mm at UN 1000 V.

There must be no foreign matter, dirt or moisture in the terminal box. Close any unnecessary cableentry eyes and the box itself to make them dust and waterproof.

Secure the parallel key for trial operation without driven units.

2.6 Operation

Vibration levels Veff 3,5 mm/s (PN 15 kW) and/or 4,5 mm/s (PN > 15 kW) in coupled operation arequite safe. In case of changes as compared with normal operation - e.g. increased temperatures,noises, vibrations -, determine the cause and, if necessary, consult with the manufacturer. Do notdeactivate protective devices, i.e. not even during trial operation. In case of doubt, stop the low-voltagemachine.

In case of an excessive accumulation of dirt, clean the air paths at regular intervals.

Refill bearing arrangements fitted with regreasing device with grease, with the low-voltage machinerunning. Check out the type of saponification. If grease outlet holes are closed by plugs, remove plugsprior to startup and reclose the holes with grease. Bearing replacement with for-life lubrication (2Zbearings) after appr. 10000 hours (2-pole) and/or 20000 hours (higher-pole); however, not later thanafter 3-4 years or as instructed by the manufacturer.

2.7 Warranty

The warranty is given on condition that these safety and startup notes as well as the notes for ancillarydevices, if any, are observed. Further details are given in the following sections of the OperatingInstructions.

The Operating Instructions include that information which is necessary for specialized staff when usingthe electric machines in industrial installations. Additional information and notes for non-qualifiedpersons and for the use of the machines in non-industrial installations are not included in theseOperating Instructions.

3. Description

3.1 Overall design of the motors

Mounting arrangement acc. to EN 60034-7

Mounting dimensions in the case of surface cooling up to frame size 200 according to FLENDERTÜBINGEN GMBH Manufacturing Standard to the modular system.

Connection designations acc. to DIN VDE 0530-8, IEC 60034-8.

Type of enclosure according to IEC 60034-5.

Type of cooling according to EN 60034-6 IC 411 surface cooling.

For details of the construction of the motors please refer to the valid catalogues.

3.2 Storage

The motors are fitted with grease-lubricated rolling bearings. The bearings of the surface-cooled motorsof standard design up to frame size 200 have for-life lubrication.

3.3 Surface cooling

Design for fin cooling, where an external fan takes in the cooling air through the openings in the fan coverand presses the air over the surface of the stator housing.

3.4 Motor frame

The stator frame and the bearing brackets are made of aluminium alloy or grey cast iron, dependingon the frame size. The cowl is made of sheet steel. Stator frame surface with cooling ribs and attachedterminal box.

3.5 Stator winding

The stator winding is designed in the thermal class (see rating plate) specified in EN 60034-1.High-quality varnished cambric wires, suitable surface insulants and the type of impregnationguarantee high mechanical and electric strength combined with high value in use and long service life.If required, the coil winding heads will be embedded in silicone rubber. Special advantages are offeredby the use of the embedding in combination with the thermal classes F and H if motors are used forparticularly arduous starting and braking conditions. In addition, embedding helps to achieve anincreased mechanical short-circuit resistance, and (in the case of surface cooling) the motor isprotected from condensed water.

3.6 Rotor

In the case of the smaller motors, the rotor has a short-circuited cage made of pressure die castaluminium, while a brazed cage is provided for the larger motors and for special startng and brakingconditions. The rotor is dynamically balanced.The balancing condition is shown in the parallel keyway; see Item 5.2, ”Assembly”. In their standard design, the motors comply with the vibration level N according to DIN VDE 0530-14/IEC 60034-14; in special cases, their vibration level is R (reduced) or S (special).

BA MC295 EN 07.978 / 23

3.7 Terminal boxes

If required, additional terminals for the monitoring devices are available inside the terminal box. Onspecial order an additional terminal box will be installed for larger motors (see dimension drawing).On special order, the larger motors will have an additional terminal box attached to them.For the number of the existing terminals please refer to the circuit diagrams to be found inside theterminal box.

3.8 Moitoring devices

Monitoring devices are only available on special request.For the technical information please refer to the circuit diagrams, the rating plates or the special orderdocuments.

BA MC295 EN 07.979 / 23

4. Incoming goods, handling and storage

4.1 Incoming goods

4.1.1 Check before installation

Check whether the motor has been damaged in transit. If the packaging is damaged to such an extentthat damage to the motor can be expected, the packaging should be removed in the presence of therepresentative of the transport company.

4.1.2 Storage safety

(Only for motors with cylindrical roller bearings)

The rotor of the motor is blocked in order to avoid bearing damage due tovibrations while at standstill:- by lock screws marked in red in the bearing end cover- or by the transport lock fixed to the shaft end.Prior to attaching the motor, the lock screws should be slackened back by 10mm und secured or the transport lock removed (see guide board on motor).Now it must be possible to turn the shaft manually.

It is recommended to release the blocking only after having fitted the drive unit.

The transport lock must be reused for subsequent transports.

Prevent trouble, thereby avoiding personal injury and property damage.The person responsible for the installation has to ensure that:- Safety Notes and Operating Instructions are available and observed;- operating conditions and technical information described in the order are observed,- protective devices are used, and- prescribed maintenance work is carried out.

4.2 Handling

Starting from frame size 132, lifting eyes for hanging up the lifting hooks areprovided on the stator construction of the motor.Check whether screwed lifting eyes are securely tightened.Lift motors only by using these lifting eyes. Several lifting eyes must alwaysbe used together.

Lifting of the motors on other parts (e.g. shaft ends) is not permitted, since thismight result in considerable damages.The motor lifting eyes are only suitable for the motor weight. Additional loadsattached to the motor, particularly gear units, must not be lifted with theselifting eyes.

BA MC295 EN 07.9710 / 23

4.3 Storage instructions

4.3.1 Storage up to 2 years

In the case of motors stored for a period of up to 2 years, the following should be observed:

Storage

The motors should be stored in a dry, dust-free room at the right temperature; this would avoid havingto use special packaging. In all other cases, the motors have to be packed in plastic sheet withhumidity-absorbing materials (e.g. Branogel) or in hermetically heat sealed film. Provide protectivecovering against sun and rain.

In order to avoid consequential damage to the bearings due to vibrations while at standstill, e.g. byadjacent running machines, the motors must only be stored in vibration-free rooms.

Motors with roller bearings are fitted with a storage lock for transport. This must be left in its blockedcondition until startup and/or refitted following an inspection or a trial run. An interlock is not requiredand does not exist if the bearing arrangement is axially preloaded.

Due to the long service life, the rolling bearings must be lubricated with special grease (e.g. StaburagsNBU 8 EP).

Startup

Prior to startup, the phase-to-phase and phase-to-chassis insulation resistance of the winding has tobe measured by specialized staff. Moist windings could cause leakage currents, flashovers anddisruptive discharges. In the case of values of < 1.5 MΩ measured at a winding temperature of 20°C,the winding should be dried. Drying can be effected by feeding the winding with single-phase alternatingcurrent. The voltage should be set such that the values of the heater current recommended in Figures4.3.1-1 and 4.3.1-2 are not exceeded. The temperature should reach appr. 80°C and act for several hours. Drying can also be effected in adrying oven.

Recommended heater circuits and maximum heater currents:

Figure 4.3.1-1: ∆-wiring diagram Figure 4.3.1-2: Y-wiring diagram

In the case of motors with bearing lock, this must be released prior to startup.

IMAX = 65 % IN IMAX = 75 % IN Y

BA MC295 EN 07.9711 / 23

Rolling bearings, lubrication

Provided proper storage for an extended period of time, one may assume that no deterioration of thegrease in the bearings will take place within 2 years. Motors with for-life lubrication can be put intooperation after having checked the insulation resistance of the winding and completed a short trial run.In the case of motors of thermal class F, a lithium saponified rolling bearing grease with a dropping pointof at least 180°C is used for a normal ambient temperature. In the case of motors of thermal class H and of certain special motors, a suitable special grease is used.

In the case of motors with relubrication system, relubrication of both bearings should be carried out asa precaution shortly after startup with motor running.The grease type, grease quantity and relubrication interval are stamped on an additional plate attachedto the motor.The values given for grease life with relubrication interval can definitely be expected for motors of IP55type of protection whose bearing arrangements are protected from the ingress of even fine dust andwater from any direction, e.g. for outdoor installation without additional protection. For motors of IP54 type of protection, these values apply with the reservation that the ecologicaldamage by dust and water will not go beyond the stipulation in DIN IEC 60034-5 with test accordingto DIN IEC 60034-5.

Note: In addition to the storage instructions, all particulars of these Operating Instructionsmust be observed. A warranty of the manufacturer can only be maintained if all of theabove-mentioned items are observed.

4.3.2 Storage under special conditions

If the motors are to be stored under the following conditions, i.e.storage for 2 years outdoor storage storage up to –50°C storage with driven machine storage under other special conditionsplease ask for the Special Storage Instructions (”ELV”) from our Service Departmentt, see Section 11.“Spare parts stock, service addresses”.

BA MC295 EN 07.9712 / 23

5. Installation and assembly

5.1 Installation

Note: Permissible coolant temperature (room temperature at the site) according to EN 60060034-1 / IEC 60034-1: max. 40°C and permissible installation altitude upto 1000 m above mean sea level (for other values please see rating plate).

Make sure that the cooling air can freely flow to the air inlet openings and flowout again through the air outlet openings and cannot be directly taken in again.Intake and blow-out orifices must be protected from blockagesand coarser-grained dust particles.

When installing the surface-heated motors starting from frame size 200, makeabsolutely sure that the condensed- water drain holes are located at the lowermost position.

Careful installation of the motors on a perfectly level support to avoid distortionswhen tightening screws. In the case of machines to be coupled, ensure perfectalignment. Flexible couplings should preferably be used. For larger motors werecommend double gear teeth couplings which, because to their large number ofteeth, bear uniformly and, because of their low weight, possess the smallestmoment of inertia.When using components such as belt pulleys, gears etc., makesure that the permissible radial and thrust loads of shafts are not exceeded.

5.2 Assembly

Fitting of belt pulleys or couplings.Start by cleaning (do not use emery cloth) and greasing the shaft end. Fit the belt pulley or couplingusing only the fitting device provided for this purpose. This can be done by using the centre hole withthread located in the shaft end. Screw corresponding threaded bolts into the thread. Now fit a steel diskof sufficient diameter to cover the hub bore of the belt pulley or coupling. Fit the belt pulley or couplingto the shaft end using a nut or a suitable hydraulic device.

Expanding the drive units by hammer blows is inadmissible because of therisk of bearing damage.When replacing the bearings, these should always be detached and fitted onlywith suitable devices and using the shaft centre hole. Use only original spareparts.

The rotor of the motor is dynamically balanced. The balancing condition is indicated in the parallel(H = half, F = whole keyway). Remove any projecting, visible keyway portion by machining. Whenmounting the drive unit, check for proper balancing condition!The balancing of the transmission parts to be fitted must be adapted to the rotor balancing. In the caseof half-keyway balancing, remove the projecting visible keyway portion by machining.

The motor and/or geared motor must only be mounted and operated in the designated mounting type(see rating plate).

BA MC295 EN 07.9713 / 23

6. Electrical connection

6.1 Connection, insulation resistance

The connection must be made by an expert in accordance with the current safety regulations. Therelevant mounting and operating instructions as well as the usual national and international regulationsmust also be observed.

Note: Observe rating plate data! Compare nature of current, mains voltage and frequency! Connect motor im compliance with the circuit diagram to be found

in the terminal box! Check wiring diagram! Observe calibration current for protective switch setting! The motor must be protected from undue heating, e.g. with a protective motor switch.

All motors are provided with a ground wire terminal inside the terminal box:

Unused cable entries in the terminal box are to be closed torsion-proof as a protection against dust andmoisture. All contact screws and nuts should be tightened firmly for avoidance of excessively hightransfer resistances.

In the case of terminal boards with U-shaped binding clips, the conductors to be connected must bebent into a U-shape and placed underneath the binding clips.

Figure 6.1: Cable connection

In the case of motors with terminal boxes having ground surfaces between cover and base, a thingrease layer should be applied for sealing and rust prevention purposes.After prolonged storage and standstill periods, the phase-to-phase and phase-to-chassis insulationresistance of the winding must be measured prior to startup.Moist windings could cause leakage currents, flashovers and disruptive discharges. In the case ofvalues of 1,5MΩ measured at a winding temperature of 20°C, the winding should be dried.

6.2 Direction of rotation and terminal designation

Direction of rotation and designation of the terminals in accordance with DIN VDE 0530-8/IEC 60034-8.

6.2.1 Standard design

In their standard design, the surface-cooled motors up to frame size 200 are suitable for both directionsof rotation.In the case of motors for only one direction of rotation, the sense of rotation is marked by an arrow onthe motor or gear unit. Terminals U1, V1, W1 to phases L1, L2, L3 (in alphabetical and/or natural order)will always result in clockwise rotation of the motor.

6.2.2 Reversal of the direction of rotation

The direction of rotation can be reversed in the case of on-line starting and pole-changeable motorswith separate windings by interchanging two mains conductors at the motor terminal board.In the case of motors with star/delta starting and pole-changeable motors with Dahlander winding, 2mains conductors at the feed-in to the motor switch must be interchanged. For a machine with only one shaft end or two shaft ends of different thicknesses, the sense of rotationwill be that direction of rotation of the rotor which an observer can establish when looking at the frontof the only or thicker shaft end.

BA MC295 EN 07.9714 / 23

6.3 Ancillary devices

6.3.1 Temperature monitoring *)

The temperature sensors for monitoring the temperature of, for instance, the stator winding, thebearings and the coolant should be connected via the additional terminals in the main terminal boxprovided for this purpose, or via one or several additional terminal boxes.The temperature sensors should be connected according to the applicable circuit diagram. Thespecifications and notes according to Item 6.1 ”Connection, Insulation Resistance” shall apply to theconnection.

6.3.2 Electronic speed monitoring *)

Basically, this consists of a slot proximity switch and the control segment. The electronic speed controlis maintenance-free.

6.3.3 Anticondensation heater *)

Heating power and connection voltage: See guide board on motor. The anticondensation heater shouldbe connected via the terminals provided in the main terminal box or via an additional terminal box inaccordance with the applicable circuit diagram.The specifications and notes according to Item 6.1 ”Connection, Insulation Resistance” shall apply tothe connection. The anticondensation heater should be switched on only after having stopped themotor. It must not be ON during motor operation.

6.3.4 Forced ventilation system *)

In the case of forced ventilation, the direction of rotation is identified separately by an arrow on the forcedventilation system. Observe direction of rotation! (See rotational direction arrow).Connect the forced ventilation system in accordance with the applicable circuit diagram included in theterminal box. The forced ventilation motor must be switched on during operation of the main motor! The forced ventilation system ensures dissipation of the heat loss while the motor is in operation. Whenthe main motor has been stopped, a temperature-dependent after-running of the forced ventilationsystem is required.

Check during startup of the main motor:

Check whether the forced ventilation is operative and activated during startup of the motor!

At an ambient temperature of 25C, twice the usable life of grease can be expected.

10.3 Connection rooms, terminals, cooling-air paths

Depending on operating conditions, the following work should be carried out:- the connection rooms and terminals should be checked for cleanliness;- the electrical connections should be checked for tight fit, and- the cooling-air paths should be cleaned.The intake orifices and the cooling surfaces must be protected from blockagesand contamination.Do not use sharp-edged tools for cleaning!
