2. GENERAL SAFETY WARNING

Electric motors are a source of electrical hazards and consequently their improper use may cause injury and/or damage to people,

animals and objects.

Read the following instructions carefully before starting up the motor; all installation, commissioning, maintenance and

protection of the electric motor must be done by qualiﬁed staﬀ in full compliance with established legislation and technical

regulations as well as the safety regulations governing the electrical equipment of machinery as declared by European

standard EN60204-1.

Please note that the present literature supplements and does not replace any established legislation, technical regulations or

safety regulations governing electric motors; it merely makes practical suggestions that qualiﬁed personnel can make use of.

It is forbidden to use electric motors in potentially explosive atmospheres unless expressly foreseen and speciﬁed on the

nameplate in compliance with European Directive 94/9/EC.

Motovario is exempt from any responsibility deriving from improper use or failure to follow current safety directives governing

electric material.

3. COMPLIANCE WITH EU DIRECTIVES – CE MARKING

Standard three-phase asynchronous electric motors (TS, TH, TP, TSX, THX, TPX, D series) and single-phase (S and HSE series) comply with

the standardised construction regulation IEC 60034-1 and therefore meet the requirements of the Low Voltage Directive 2014/35/EU.

The electric motor, considered as a component, is compliant with the following directives:

• Directive ROHS 2011/65/EU relating to the prohibition or the limitation of the use of noxious substances in electrical and electronic

equipment.

• Directive ErP 2009/125/EC on ecological designing of energy-using devices and in particular EC Regulation

no. 640/2009 (and subsequent UE modication no. 4/2014) on the ecological design of electric motors.

• Directive EMC 2014/30/EU relating to intrinsic characteristics in relation to emissions and levels of immunity.

All standard mounting position motors in continuous operation and powered from the mains are compliant with general standards

EN 61000-6-2, EN 61000-6-3, 61000-6-4 on electromagnetic emission and immunity; in the case of brake motors (TBS, TBH, TBP, TBSX,

TBHX, TBPX, DB RRSD series) or full wave rectier (DBR) the lter is implemented by connecting a 440Vac 0.22μF class X2 condenser in

parallel to the AC power, as per EN132400; the half-wave rectier type RV6 has no integral lter and is thus suited to installation with

the lter upline of the machine (to be done by the client). Follow the instructions of the devices' manufacturers in case of intermittent

malfunctions and interferences generated by the triggering devices, power supplies with inverters, systems with encoders, etc. All

electric motors are intended to be integrated in equipment and complete systems and must never be started until the equipment

they are installed in is compliant with Machinery Directive (Certicate of Integration - Directive 2006/42/EC Ann. II B). The compliance

of a complete installation with the "Machinery Directive" and the EMC Directive is the responsibility of the machine's manufacturer.

According to EC Regulation no. 640/2009, starting from 01/01/2015 the motors of the TH series (IE2, high eciency) with power greater

than or equal to 7.5 kW can be started in the European Union only if supplied by an inverter. From 01/01/2017 this provision applies to

the motors of the TH series with power greater than or equal to 0.75 kW.

USE AND MAINTENANCE MANUAL FOR ELECTRIC MOTORS

5. MECHANICAL INSTALLATION

Before installation please check that:

1) the electric motor is not visibly damaged (whether damaged in transit or during storage).

2) the information on the nameplate corresponds with the features of the electric motor and its intended use; the power supply voltage

matches the mains voltage; the permitted voltage tolerance is ±10% for 230/400V 50Hz and 265/460V 60Hz, and ±5% for other voltages

and/or single-phase motors.

3) the ambient temperature is between -15°C and +40°C (+50°C 2- and 4-pole TS motors with nominal power >= 0.75 kW); in addition,

the altitude must be < 1000m above sea level; ambient temperatures outside this range and/or higher altitudes require the application

of a corrective power factor (see product catalogue).

4) If the environment features sudden temperature changes with possible consequent condensate formation, it is recommended to

request the condensation heaters and/or the condensate discharge holes.

5) The IP protection rating given on the nameplate is suited to the environment under the terms of IEC 60034-5.

6) In outdoor installations, protect the motor from the direct sunlight and, if possible, from the atmospheric agents.

Use the provided attachment points to lift the motor; the eyebolts on the motor are for lifting the motor only and not any other

equipment coupled to it; ensure that the systems mounted to the motor match the electric motor's specications.

Preliminary tasks:

1) remove any fastenings and protective material used for shipping (e.g. guards on the ends of the motor shaft) and check that the shaft

turns freely (for TBS – TBH – TBP – TBSX - TBHX - TBPX – DB series brake motors, rst release the manual release lever if present);

2) carefully clean the ends of the shaft with a normal solvent to remove any rust protection, contaminants and similar matter; take care

that the solvent does not get into the bearings or comes into contact with the seal ring lips and damages them;

3) check, especially after lengthy storage, that the motor has not absorbed humidity, by measuring the insulation resistance which must

be < 10MΩ at 20°C; take the measurement by applying a direct current of 500V between the phases towards GND; the windings must

be discharged immediately after the measurement has been taken. If the insulation resistance is insucient the motor must be dried

with hot air or using an isolation transformer, connecting the windings of each phase in series and applying an auxiliary AC current of

10-20% of the nominal current, until the resistance measurement is satisfactory.

Installing the motor:

1) take care to secure the motor adequately in relation to its weight, mounting type and position;

2) assemble the motor on a at, rigid, vibration-free and deformation-resistant surface; align the motor carefully with the driven

machine to avoid inadmissible stresses on the shaft and observe the overhung and axial loading specications (see product catalogue);

misalignments and forced locking can result in hazardous overheating;

3) if the motor construction type is IEC B14, the four retaining screws must be screwed in the ange even if they are not necessary. It

is recommendable to apply sealant, such as Loctite 242, on the retaining screws thread. The maximum screwing depth in the bearing

shield is 2 x d, where "d" is the threaded hole;

4) vertical installations must include measures to prevent foreign bodies falling into the ventilation slots; in such case, we recommend

using a fan cover with awning (compulsory in case of self-braking motor);

5) during assembly, avoid damaging the bearings by using the shaft as a stop after removing the fan cover; do not knock the end of

the shaft;

6) the motor shaft is dynamically balanced and complete with half key from size 90 upwards, with normal vibration; make sure that any

parts to be locked to the motor shaft are balanced with half key; if using double-ended shaft motors, take care not to start the motor

until the unused key has been secured.

7) the motor must be mounted in such a way that the nameplate data is legible, the terminal block box can be inspected, the motor

compartment can be cleaned, there are no moving parts outside the guards (e.g. fan cover), the assembly is suciently ventilated

without bottlenecks or machining residue, dust or uids in the air supply, and that nothing is blocking normal dispersal of heat; nally,

ensure that there is sucient distance between the fan cover holes and any external protective devices which could potentially block

the inow of cooling air.

8) in particularly humid conditions: make sure, if possible, that the cables enter the terminal block box from below, and check for

condensation; if there is a condensation drain hole, drain the condensation, then ret the plug to restore the box's IP rating. Do this only

with the power supply visibly shut o (breaker open). If there are anti-condensation heaters, make sure the motor is not powered up or

rotating before turning them on; also make sure the heaters' power supply is compliant with their ratings.

6. ELECTRICAL INSTALLATION AND START UP

1) Connect the motor to the mains as shown in the diagram inside the terminal block box (the wiring diagrams are also included at the

end of this manual).

2) Do not connect up or start the motor if the wiring diagram is absent.

3) Do not start the motor with the key unengaged.

4) Before making the connections, check that the motor's wires are properly tightened down to the terminal block; to connect the cable,

use the parts kit in the bag supplied with the motor, paying particular attention to the maximum tightening torques; the terminals used

to hook up the cable must be isolated to ensure the minimum distances between the live parts and inactive metal parts; the cable gland

must be suited to the external diameter of the cable used; all unused cable entry points must be sealed to restore the box's IP rating.

5) As well as the main power terminals, the terminal block box may also contain the cable terminals for the thermal protective devices

and/or condensation heaters and/or the brake (if the motor in question is a brake motor with separate power supply). The cable

terminals in the terminal block for thermal protective devices and condensation heaters are usually free. For connecting up brakes with

separate power supplies please refer to the relevant section.

Motors can also be tted with incremental encoders and/or an external forced ventilation capacity (servo-ventilation). Please consult

the relevant sections.

6) The power and GND cables must comply with established practice and standards, and be properly insulated and rated for the current

draw; the connection cabling and cable cross sections must comply with EN60204-1.

7) All motors are equipped for grounding inside the terminal block box and outside on the motor casing; the GND clamp points are

marked with the relevant symbol.

8) Secure the GND cable to prevent its slackening (use an elastic washer between the terminal and the bolt) and rotating (use only split

cable terminals).

9) Before starting up the motor, check its direction of rotation; if it is required to run in the opposite direction from the default direction,

for three-phase motors (series TS, TH, TP, TSX, THX, TPX, TBS, TBH, TBP, TBSX, TBHX, TBPX, D; DB) simply swap 2 phases; for single-phase

motors (series S), refer to the wiring diagram. The direction of rotation is clockwise when seen from the drive side.

10) If a backstop device is present, do not start the motor in the stop direction; for inspection reasons, the backstop can only be

operated once in the stop direction at a voltage less than half the power voltage.

11) After wiring the unit, ret the terminal block cover with its gasket.

12) For brake motors, check the operation of the brake and its braking torque before starting the motor.

13) For motors of the TSX, THX, TPX, TBSX, TBHX, TBPX series, smear sealant (like LOCTITE 5331) on the cable glands and the closing

plugs and tighten them correctly; properly seal the cable inlet; thoroughly clean the sealing surface of the terminal block box; in case

of installation in particularly aggressive environments, seals (to be replaced if damaged) must be stuck on the terminal block box cover

with suitable sealant (like LOCTITE 3020); if present and if necessary, touch-up the anti-corrosion pain with kit that can be supplied

upon request.

14) Do not touch the motor's housing while it is running as it can reach more than 50°C.

USE AND MAINTENANCE MANUAL FOR ELECTRIC MOTORS

7. INCREMENTAL ENCODER

Motors can (optionally) be supplied with standard or low-resolution incremental encoders (for further information see product

catalogue).

Safety information

1) Wiring must always be done by fully qualied specialist personnel.

2) Shut o the power to all equipment/machinery involved in the wiring process.

3) Do not connect or disconnect the encoder when powered up as this may irrevocably damage it.

4) A suitable ground connection must be in place for the encoder to work properly. The cable screen must be grounded at both ends to

ensure the right shielding from EMC interference.

5) Do not bang or knock the encoder shaft in any way.

6) The standard incremental encoder either comes with or without connectors. Connectors are never supplied with the low-resolution

incremental encoder. Please consult the following wiring diagrams:

8. FORCED VENTILATION

It may be necessary on all model sizes to resort to forced ventilation (cooling method IC416), obtained by means of an axial ow

servo-fan whose air ow rate is independent of the speed of rotation of the drive shaft. The power supply, independent from that of

the electric motor, is provided via a connector applied directly on the fan cover (single phase version 230V 50-60Hz, sizes 63-90), or by

means of a separate terminal block box mounted on the fan cover (single-phase 230V 50-60Hz sizes 100-132 and three-phase 400V

50-60Hz sizes 100-132).

Forced ventilation has been designed as a kit; therefore it is possible to modify a standard self-ventilated electric motor (IC411) into a

motor with forced ventilation (IC416) by following these simple instructions:

- disassemble the standard fan cover, unscrewing the fastening screws from the motor casing

- remove the fastening bush of the plastic fan and remove the fan with the help of a tool;

- assemble the forced ventilation kit by tightening it to the motor casing with the fastening screws of the fan cover just disassembled.

The application of the forced ventilation kit will increase the length of the motor (see dimensional tables).

USE AND MAINTENANCE MANUAL FOR ELECTRIC MOTORS

9. ELECTRIC MOTOR PROTECTION

All electrical equipment must be protected against damage deriving from trouble or abnormal operation. The following phenomena

must be taken into consideration:

- overcurrents deriving from short-circuiting;

- overload currents;

- break or dip in supply voltage;

- motor overspeed.

In addition, for the purposes of safety, there needs to be protection against direct contact with live parts and indirect contact with parts

normally not live but which could become live in the event of insulation failure.

• Overcurrents deriving from short-circuiting.

Protection can take the form of: fuses, overcurrent relays or thermal cutouts.

Fuses interrupt the electric current, while the over-current relays and thermal cutouts open the circuit via automatic switches or

contactors. These protective devices must be installed upline from the conductors to be protected.

Overload and short circuit protection can take the form of: an automatic magnetothermic switch which must have sucient interrupting

capacity to interrupt the short circuit current, capable of protecting an electrical circuit from both overloads and short circuits; or switches

which, although capable of protecting electrical circuits from overloads, require additional fuses to be installed further upline to prevent

damage from short circuits. These must be time-delay fuses since motors draw larger than normal currents for up to several seconds

while coming up to speed.

• Overload currents.

Overload protection must feature in all motors with a power rating over 0.5kW which are normally in constant

operation; however, it is recommended for all other motors as well. Protection normally takes the form of thermal cutouts installed on all

live conductors except for neutral; in single-phase motors only one ungrounded live conductor is permitted.

The time constant of the protective device must be as close as possible to that of the motor; if this stringent requirement is not met, then

the safety device may become inecient or circuit interruption ill-timed. This is especially the case for intermittent motors or motors

which are subjected to a high number of operational processes (start-up, stop, reversing); here it is advisable to use temperature sensors

incorporated into the motor (PTC thermistors or bimetal thermal fuses) that can interrupt the current if the internal motor temperature

exceeds a certain level. These devices are also recommended in reduced cooling circumstances and all other situations where the motor

may overheat, but not necessarily because of an overload current.

Please bear in mind that such devices may not be sucient to protect the motor if the rotor is locked; in this case it may be worthwhile

to connect them to the thermal ones on the phases.

In general, equipment must be designed so that the motor does not automatically restart after the thermal protective device has been

triggered. In certain production cycles, the sudden halting of a motor (especially if not coordinated with other motors in the cycle) may

damage it; in this instance, the thermal protective devices can initially send a visual or audio warning signal to the operator, and then

eventually shut down the motor if no action has been taken. The level of action to be taken and the relevant time delays must be set so

as to avoid any kind of potential hazard. If the motor is powered via a converter (i.e. inverter), then it can also be protected by limiting

the absorbed current; this limit is generally set at a value superior to the nominal current so that the motor can withstand predicted peak

loads and have a sucient starting torque. As a result, the motor must be connected to another device capable of intervening if overload

conditions persist over a certain period of time.

• Break or dip in supply voltage.

In situations where a dip or interruption in the supply voltage may result from faulty wiring, an

undervoltage device must be in place that guarantees suitable protection (i.e. machine shut o) at a set voltage level. If machine

operation can withstand a voltage interruption or dip for a short period, an undervoltage time delay device can be tted. The operation

of the undervoltage protective device must not interfere with any machine shutdown commands.

• Motor overspeed.

Motor overspeed can occur if the converter used to power the motor is faulty, or if the brake action is insucient or

absent, causing the load to drag the shaft. Protection against this is vital in that overspeed can be hazardous. Preventive measures can

be taken, such as motor speed sensors (centrifugal circuit breakers or voltage relays connected to tachymetric dynamos) which cut o

the power supply to the motor, and braking devices, which are necessary where the interruption of the electric current is not enough to

stop the driven load (e.g. lifting).

• Protection against direct contact with live parts.

In order to minimise risk of direct contact with the live parts of the motor, these

have been housed in the motor casing; furthermore, the terminal block box can only be opened using a special tool. The removal of

the terminal block box cover for maintenance purposes must only be carried out by qualied personnel and the power supply must be

visibly shut o, including auxiliary circuits (i.e. for condensation heaters), so that no accessible parts stay live.

In the case of live parts that remain energised after power has been shut o, e.g. capacitors in single-phase motors, then discharge these

capacitors (with the power supply visibly shut o) before proceeding.

• Protection against indirect contact with live parts.

Protection against indirect contact, i.e. contact due to insulation faults that bring

external metal parts into contact with live parts, is mainly accomplished by connecting all the accessible parts to a protective ground

conductor and by using protective devices that act by cutting o the power when, due to a fault in the winding, current ows towards

earth.

www.motovario.com

The fundamental principle behind this kind of protection is, in the event of fault, to prevent a ow of voltage between an accessible part

and earth or between two simultaneously accessible parts, that lasts long enough to cause serious bodily harm if such parts are touched.

A distinction can be made between:

- a protective wiring system with a protective conductor grounded independently from the mains. This protection can be eected by

means of an overcurrent circuit breaker or a residual current circuit breaker;

- a protective wiring system with a neutral conductor grounded at origin and used as a protective conductor (in this case it is not possible

to use the residual current protection and so overcurrent circuit breakers are necessary).

Please refer to the relevant regulations and standards.

The operation of protective devices must be both coordinated and allow for individual device selection so as to adequately protect lines

and equipment. The automatic reset of protective devices after they have tripped is strictly forbidden as this can be hazardous.

In addition, trained personnel must manually reset the system which the electric motor belongs to or is the main component of.

When there is a neutral conductor, the installation of protective devices on the various conductors must take into account the type of

connection (system) used.

10. MAINTENANCE / SPARE PARTS

When ordering spare parts, quote the type of motor, product code and serial number given on the nameplate.

Before working on the motors or in their vicinities, shut o the power supply and wait for all moving parts to come to a halt; ensure that

the motor cannot restart as a result of moving parts dragging the shaft; nally, wait for the motor's surface temperature to drop below

50°C (burn hazard).

Periodic maintenance:

- inspect the motor at regular intervals;

- remove powder, dust, oil and dirt on the fan and fan cover; this helps air to circulate and keep the motor cool;

- check the condition of the seal rings and V-rings;

- check the electrical and mechanical connections and the tightening/anchor nuts and bolts;

- check the condition of the bearings, listening for strange noises or vibrations;

In the event that the motor needs to be disassembled and its internal components examined, then qualied personnel must be

enlisted who use appropriate equipment and follow the relevant procedures; Motovario is in no way responsible for any damage

or injury that results from the improper use of its parts by unauthorised personnel. Removing parts without the manufacturer's

authorisation voids the warranty and the manufacturer is not liable for any claims resulting therefrom.

11. ASSEMBLY/DISASSEMBLY INSTRUCTIONS

1. Disassembly: free the motor from its couplings with the operating part. Take o the fan cover and fan, removing the relative fastenings.

Remove the key. Unscrew and remove the screw tie bars holding the motor together. Take out the ange or front shield, extracting

it from the casing and from the bearing. Extract the rotor from the support of the opposite shield, taking care not to damage the

winding.

2. Replacing the bearings: extract the bearings with a special extractor. New bearings must be mounted using a press or buer resting

on the inside ring, or using the heat mounting method. Pre-lubricated shielded bearings that do not require greasing should be used

for all kinds of motors.

3. Stator rewinding: to be done at qualied workshops only; this however will invalidate the Motovario guarantee.

4. Assembly: follow the disassembly instructions in reverse order. The only warning is to take care when mounting the seal rings,

after cleaning their seats and turning the rings correctly with their concave surface facing outwards. On completion of maintenance and

inspections, run functional and safety checks (thermal protection, brake, etc.).

12. DISPOSAL AND RECYCLING

The crossed-out wheelie bin symbol shown on the plate or on the label indicates that the motor at the end of its useful life

must be disposed of separately from other waste. The adequate separate collection of the motor allows it to be recycled,

treated and disposed of in an environmentally compatible manner contributing to avoid possible negative eects on the

environment ad on the health, and favouring the reuse and/or recycle of its materials.

The motor must be rst of all disassembled following the indications in the previous paragraph. The packages materials can be recycled:

oils, greases, detergents, solvents and paint residues must be disposed of in compliance with the prevailing laws and regulations.

The materials remained after the motor disassembly (wrapped stator: copper, steel, aluminium; rotor: steel and aluminium; anges,

shields, feet and terminal block box cover: aluminium or cast iron; bearings and pinions: steel; seal rings and electronic waste: hazardous

waste) must be separated and disposed of in compliance with the prevailing laws and regulations.

Adjustment and maintenance

The braking moment is xed and is indicated on the motor nameplate.

Adjusting the gap

For correct brake operation, the gap between the brake magnet and the moving coil must be in the range (S

- S

max

) shown in the table;

it can be adjusted with the mounting bolts and the locknuts, with a feeler gauge to check the actual gap.

Release lever play adjustment (if present)

When there is a manual release lever, adjust the free travel value X of the lever (tightening/loosening the nuts) to a level equal to or

greater than the one indicated in the table before releasing.

Maintenance

The scheduled maintenance interval will depend on actual braking duty and the work done by the brake between successive adjustments

W1. When running maintenance, check that the thickness of the friction member is no less than 1 mm (in this case replace the brake disk),

adjust the gap, check the braking torque, and check any play due to excessive wear during operation.

PLEASE NOTE: the eective values may be aected by the ambient temperature and humidity, the brake temperature and the wear

of the friction members; the maintenance intervals refer to the brake adjusted to a medium gap setting, nominal voltage and separate

power supply; as regards the braking torque, allow for a running-in period in which the brake lining adapts to the engine shield braking

surface, the duration of which (number of cycles) will depend on the actual braking load. Once the brake has been run in, in nominal

operating conditions a deviation from the declared value of ±10% is always acceptable.

USE AND MAINTENANCE MANUAL FOR ELECTRIC MOTORS

Connecting up the FM brake

If the brake is powered directly by the motor itself, this is called direct power supply, if it is powered separately, it is called separate

power supply. What follows is a more detailed explanation, which makes reference to the diagrams at the foot of the page.

1. Direct brake power:

supply cables on the AC side of the rectier are connected to the motor's power terminal board; when you

power up the motor, the brake coil is automatically energised and the brake is released; when power to the motor is shut o, the brake

automatically brakes the motor. During this phase, the brake response time t

has to be added to the delay R generated by the inertia of

the load and by the energy accumulated by the motor. R changes in every motor and – as it depends on the load – cannot be previously

calculated.

2. Separate brake power, brake opens only from the AC side:

the brake is powered, via the rectier, by terminals separate from those

of the motor. In this case stop time t

does not depend on the characteristics of both the motor and load.

3. Direct brake power, DC side opens:

connection possible on the basis of type 1, if one can cable the rectier's rapid braking contact

(DC side opening) as shown in gure 3. Despite the direct power supply (see point 1), the braking response time is independent of the

characteristics of the motor and load, and is signicantly shorter than that of case 2 (t

< t

). This connection is thus an alternative to the

use of rapid braking rectiers (RSD and RRSD).

4. Separate brake power, AC and DC sides open:

connection possible starting from type 2, if the rectier's rapid braking contact (DC

side power o) can be hooked up as shown in diagram 4. Response time equal to that of type 3, hence this connection is an alternative

to the use of rapid braking rectiers (RSD and RRSD). The advantage over the previous case is that during brake operation the energy

stored by the motor does not have to be absorbed by the rectier, thus giving it a longer service life.

Motovario supplies brakes hooked up as shown in types 1 and 2

to be specied as "direct" or "separate" brake power respectively in

the order. Type 3 and 4 connections must be implemented by the client.

If SBR rapid release rectiers are used, the brake release time reduces from t

to t

(see graphs below).

In the event of independent power supply of the brake from a direct current power source, and thus minus rectier (ex. 24Vdc), the

supply cables of the brake are set inside the terminal block box and connected to a strip connector-type ying terminal block. In this

instance, refer to case 4 for the response times (power source excluded).
