The air insulation distances indicated in the followingtable must be maintained when connections aremade among conductors having different potential:

2.4.1 Thermal protectionWith PTC or PT 100 thermistors used for controllingtemperature class, the user, in compliance with theessential safety requirements provided for underpoint 1.5 of the European Directive 94/9EC, mustalternatively use:• use a cut-out in compliance with IEC 61508 stan-

dard• use a cut-out that automatically switches to safety

position in case of a failure (fail-safe)• use a dual protection circuit.

2.4.2 Anti-condensation heaterThe anticondensation heaters must be fed from adifferent line from the motor power supply one.Check that the power voltage matches the one indi-cated on the nameplate. The heaters must not ope-rate when the motor is powered.Check the type of auxiliary present on the motor bylooking at the “auxiliaries marking diagram”.

Connections must be made via cable or conductorentries in a conduit conforming to the IEC 60079-14standard.

The cable entry must be made without modifying thespecific properties of the protection type as indicat-ed in the following standards:- IEC 60079-1 (§13.1, 13.2) for Ex-d motors (flame-proof protection);

- IEC 60079-7 for Ex-de motors (increased safetyprotection);

- IEC 61241-0 for Ex-tD motors (protective enclo-sure against dust penetration).

When the cable entry is made using a cable gland,the type of cable gland must be selected correctly inrelation to the type of plant and the type of cable.The cable gland must be tightened fully until the sealrings ensure the necessary pressure:• to prevent transmission of mechanical stress to

the motor terminals• to ensure the mechanical protection degree) of

the terminal box.

Cable entries for Ex-d terminal boxes must consistof seal bushings or Ex-d cable glands certifiedaccording to the IEC 60079-0, IEC 60079-1Standards and the ATEX Directive (94/9/CE).Furthermore, they must have a minimum IP55 pro-tection class (IP65 for the GD category).

Ex-e cable glands certified according to the IEC60079-0, IEC 60079-7 and the ATEX directive mustbe used for the Ex-de terminal boxes. Furthermore,they must have a minimum IP55 protection class(IP65 for the GD category).

The blocking fitting and cable must be selected onthe basis of the maximum operating temperaturerequired for the cable, and indicated on the warningplate if over 70°C.

3. Motors without terminalbox with cable leadingout of plate

When the motor comes without a terminal box, themotor’s enclosure is closed with a plate with thepower supply cable leading out of it. To install cor-rectly, the user must follow the instructions below.

An armoured cable leads out of the motor plateclamped by an appropriate cable gland.Free cables lead out of the motor plate featuring theclamping coupling, and are used to supply themotor. The user must protect power supply cablesfrom potential damage arising from mechanicalstress, and must connect ends of cables accordingto one of the safety methods provided for by stan-dard IEC 60079-0, in conformity with engineeringrules in force for the place where the motor is to beused.

Should the motor come complete with coupling andflexible tube, the user must connect the end of thewires directly onto the terminals located in the rele-vant box.

In this case the case securing accessories areapplied by the installer, who will have to use versionsthat match the protection type and ambient temper-ature of the plant. The case must be closed using alocking joint compliant with standards EN 60079-0and EN 60079-1 for motors category II 2G and stan-dards EN 61241-0 and EN 61241-1 for motors cate-gory II 2GD. The free wires leading out of the motorplate are used to supply power to the motor andmust be protected against potential damage causedby mechanical stresses. Users will have to connectthe cable terminals using one of the protection typesspecified in standard EN 60070-0.

4. Motors without fan

Ventilation is supplied by a fan directly coupled tothe motor. Ensure that the motor ventilation is notimpaired in all operating conditions and that the tem-perature limits allowed by the insulation category Bare complied with.

Fans must comply with the EN 1127-1 standard andany possible product standards referring to fans.

In areas with combustible dusts, the provisions ofthe IEC 61241-1-1 standard must be observed.

The motor is without a fan. The following limitationsmust be observed:

- For “S1” operation, the motor power output isderated by 50% to comply with the limits allowedby insulation class B.

- For “S2” operation, regular power output can beused provided the motor does not work longenough for it to reach the temperature limits ofinsulation class B. Said time limits are indicatedon the plate.

5. Motors with forcedventilation

Cooling is assured by ventilation provided by an aux-iliary flameproof motor, covered by separate certifi-cation, fitted on the back of the main motor.

The user must have a safety device fitted enablingthe main motor to be started only once the auxiliarymotor is running.

In addition, motors must be equipped with PTC orPT100 thermal probes, which must be connectedwith a cut-out disconnecting the motor’s power sup-ply. This cut-out must have a manual reset.

6. Motors for lowtemperatures

Motors designed to be used at low ambient temper-atures have construction characteristics that makethem ideal for use at temperatures between -20°Cand -50°C.The minimum and maximum temperatures are indi-cated on the nameplate.

To use these motors correctly, special attention mustbe given to the following points:• Any auxiliary devices used, such as pre-heating

coils, must be powered when the motor is notrunning.

• Fixings are in A480 STAINLESS STEEL and if,replaced, they must be replaced with fixings ofthe same quality.

• The fan guards are made of stainless steel and thecooling fans of aluminium. If replaced, these mustbe replaced with components with the same qual-ities.

• The terminal boards / passing terminals are espe-cially certified for these temperatures, and mustbe replaced with original components.

• The grease used to protect the joints must besuitable for the temperature fluctuation rangesexperienced in the plant (e.g. “Aereo 55” type).

• The cables used to power the motors and thecable glands on the terminal board box must besuitable for the ambient temperatures. The insu-lation materials in particular must be suitable forthe temperature fluctuation ranges the motors aresubject to, both as a result of seasonal changes inthe ambient temperature, and due to temperatureincreases brought about by the motor runningwhile loaded.

7. Motors suitable forfrequency converterdrive

For operation with an inverter, motors must beequipped with PTC or PT100 thermistors inserted inthe winding to ensure compliance with the limits ofthe temperature class.

If the motor temperature class is T4, the user mustconnect the PTC or PT100 terminals to a trippingrelay ensuring that the power supply is cut off when-ever a dangerous temperature is reached. The resetof said cut-out must be performed manually only,and not automatically.The user, in compliance with the essential safetyrequirements provided for under point 1.5 ofEuropean Directive 94/96 EC, must:• use a cut-out in compliance with IEC 61508 stan-

dardor• use a cut-out that automatically switches to safe-

ty position in case of a failure (fail-safe)or• use a dual protection circuit. As an alternative, the

user can employ a dual device such as that indi-cated in section 5 for forced ventilation.

When temperature class T5 or T6 the condition foruse is indicated on the certificate.

Rated performance relating to operation at mainspower frequency cannot be maintained if poweredby an inverter. In particular, power output could besignificantly reduced to maintain the assigned tem-perature class and to avoid damage caused by over-heating.

Inverter motors have an auxiliary plate. Before start-ing the motor, check the ratings (kW - Hz - torque)indicated on the auxiliary plate. The user must con-tact the manufacturer if this information is not pro-vided.Induction motors supplied from the mains conformto the immunity and emission limits relating to elec-tromagnetic compatibility as foreseen by the stan-dards.

When power is supplied by a frequency converter,the installer bears responsibility for checks and anymeasures required to comply with immunity andemission limits as laid down by the standards.Thechoice of the type of frequency converter must bemade taking into account that the motor must not besubjected to voltage peaks exceeding 1100V, whichwould significantly reduce the life of the windings

insulation. It is necessary to consider in this respectthat the voltage peaks value is also influenced by thelength of the power supply cable.

When the motor comes with forced ventilation pro-vided by an auxiliary motor, motors with IC416 cool-ing, the user must follow instructions given in point5.1 (Cooling method IC416).

8. Motors with brake

In addition to the provisions for normal motors,motors with brake require special measures to guar-antee correct operation.

Motors with brake are normally provided for horizon-tal operation. If positioned vertically the brake couldbe subject to operational malfunctions. Observe theinstallation conditions provided upon ordering.

The electrical connections must be set up by quali-fied personnel in full observance of the informationgiven in point 2.

When setting up the connection, reference must bemade to the diagram provided with the motor, bear-ing in mind that the brake can be provided with dif-ferent types of power supply:- Three-phase power supply (with voltage the same

as or different to that of the motor)- Single-phase power supply (always different to

that of the motor)- Direct current power supply (always different to

that of the motor)Before setting up the connection, check the informa-tion provided on the nameplate.

NB

• In the event that the motor is powered byinverter, the brake must have its own powersupply separate to that of the motor.

• The brake is provided already calibrated withthe braking torque requested upon ordering.No adjustments or checks of the brake itselfare required before commissioning.For disassembly and assembly refer to the rel-evant use and maintenance manual.

10. Repair of motorsCategory 2G, 2D

Repairs made to motors Category 2G, 2D shall beexecuted in compliance with the criteria specified inthe IEC 60079-19 standard.

If repairs are not executed by the manufacturer, theymust be carried out at workshops which have thenecessary equipment and with adequate technicalexpertise concerning the motor protection types.

If repair work has to be performed on parts that influ-ence the protection against explosions, the motorconstruction data must not be changed (for exam-ple: dimensions of joints, winding characteristics,etc.) and if parts are replaced, this must be with orig-inal components.

A written report must be prepared with the detailedindication of the work carried out.

If after the repair work has been completed, themotor complies entirely with the standard and withthe certificate, an additional nameplate shall beaffixed to the motor (without removing the originalnameplate) showing the following marks:

• Symbol R

• name or trademark of the repairer

• serial number given to the repair operation by therepairer

• date of repair

If following a repair that modifies relevant aspectsconcerning protection against explosions, the motordoes not comply with the certificate, the originalnameplate must be removed and the motor can nolonger be considered suitable for use in areas wherethere is danger of explosion.

In order to be utilised in such areas the motor mustbe examined again by a competent certificationbody.

9. Inspections andmaintenance ofmotors Category 2G, 2D

The inspections and maintenance of motorsCategory 2G, 2D shall be executed in compliancewith the criteria of the IEC 60079-17, IEC 61241-17standards.

The electrical connection terminals must be tight-ened fully to avoid high contact resistances and con-sequential overheating.

Care must be taken to ensure that the insulation dis-tances in air and on the surfaces between the con-ductors are maintained, as established by the stan-dards.

All bolts used to secure both motor and terminal boxmust be tightened using the torque values as indi-cated in the table TIGHTENING TORQUES par. 2.7.All screws utilised to seal the motor and the terminalboard shall be tightened fully.

Replacement of gaskets and cable entry parts shallbe executed using components that are identical tothe components supplied by the manufacturer toensure the protection degree is maintained.

The surfaces of flameproof joints must not bemachined and sealing gaskets different from thosesupplied by the manufacturer must not be inserted.These surfaces must be maintained in a clean con-dition. A thin layer of non-hardening grease must beused against corrosion and to prevent water fromentering. This grease layer must be renewed at everydisassembly.
