Explosion protection designationProduct Description

2 Product Description2.1 Explosion protection designationRevision of the standards

With the revision of the explosion protection standards, new designations have beenimplemented internationally (IEC), the so-called Equipment Protection Levels (EPL).Parallel to the explosion protection categories, the EPL specifies the applicability of aunit according to the zone categorization for potentially explosive atmospheres.With the revision of EN 60079-0 from 2010, the EPL have also been adopted toEuropean standards. The following table shows the assignment of the EPL to theexplosion protection zones.

With the revision of the IEC 60079 "Electrical apparatus for potentially explosiveatmospheres", dust explosion protection has been integrated in this set of standards aspart 31. The separate dust standard IEC 61241-1 has become invalid with the releaseof IEC 60079-31 in November 2008.The international standard IEC 60079 will be harmonized as EN standard with the samenumber and the same content in the foreseeable future.The equipment group III for dust has also been implemented as part of this integration.As a result, there are 3 equipment groups in international standards. The following tableshows the three equipment groups.

In addition, the new equipment group III has been split up into three subgroups "A", "B"and "C" depending on the type of dust. The following table shows this division.

The specific values of equipment groups IIIA to IIIC for the dust/air mixture correspondto the previous designation IIA to IIC for gas/air mixtures.Previously, the designation IIA to IIC has only be used for motors in EX-d design(flameproof). Now, the designation of motors of a protection type with increased safety"e" is changed from II (without letter) to IIA, IIB, or IIC. This includes requirements for theprevention of electrostatic charge of plastic surfaces (e.g. fans) and coated, metalsurfaces.

2 Explosion protection designationProduct Description

EX labeling of motorsThe standard changes described above also cause a change of the EX designation ofmotors that must also be specified on the motor nameplate. The following table showsthis change (example).

With the designation of the explosion protection, you have to distinguish between thedesignation according to Directive (e.g. II3D) and the designation according to standard(e.g. Ex tc IIIC T120°C Dc).

Equipment sold within the scope of the European Directive 94/9/EC must be labeledaccording to Directive 94/9/EC in addition to the standard designation. It is important tonote that the Directive designation (e.g. with II) and the standard designation (e.g. withIII) are two different designations.As the directive contains both gas and dust atmospheres in category II, a motor can bedesignated with II3D according to the directive and with IIIC according to the standard,for example.

Motor protection Motor protection must be in accordance with the respective approvals. Two basicprotection variants are distinguished:1. Motor current circuit breaker2. Temperature sensor (PTC resistor, SEW designation: TF)The following additional features can be selected as well, if available:For 1: TF, KY or PTFor 2: KY or PTYou find detailed information in the "Explosion-Proof AC Motors" catalog.The following table shows the type of motor protection required according to therespective approval:

Drive technology in accordance with EU Directive 94/9/ECProduct Description

2.2 Drive technology in accordance with EU Directive 94/9/EC Why explosion protection?

Special measures are required for the operation of systems and machinery in areas withpotentially explosive air/gas or air/dust mixtures. If mixture formation cannot be prevent-ed, specially protected drives must be used. Applicable standards and regulationsgovern the use of equipment within existing hazard zones. They also stipulate the qualityrequirements that must be met by drive manufacturers.

Harmonized European design provisionsEU Directive 94/9/EC provides binding minimum requirements to be applied within theEuropean Union to equipment intended for use in potentially explosive atmospheres.The minimum requirements are defined in the European standards. These standardsare identical with the international EX standards on the IEC level. This means motors inaccordance with 94/9/EC also meet the requirements of the respective internationallaws. In relation to drives, the directive covers motors as well as all other electrical andmechanical components such as gear units, mechanical variable speed gear units,brakes, forced cooling fans, integrated frequency inverters, sensors, and actuators.Directive 94/9/EC defines the minimum requirements for units and divides the units intocategories.The requirements for production plants, division into zones and the assignment of equip-ment categories to zones are defined in EU Directive 1999/92/EC.Naturally, EU Directive 94/9/EC also applies to all products which are manufacturedoutside the EU and imported into the EU. To indicate compliance with EU Directive94/9/EC, explosion-proof units also bear the CE mark on their nameplates.

Explosion-proof drives from SEW-EURODRIVEDrives from SEW-EURODRIVE for potentially explosive atmospheres have the follow-ing characteristics:• Included are all product areas from mains operated AC gearmotors and MOVIMOT®

gearmotors with integrated frequency inverters through to controlled drives forparticularly exacting applications.

• All components can be combined with one another according to the rules of theSEW-EURODRIVE modular concept.

• All drives satisfy typical market requirements in terms of their power range andfunctions.

RegulationsProduct Description

Dividing explosion-proof equipment into categoriesAccording to EU Directive 94/9/EC, explosion-proof equipment is divided into catego-ries. The category specifies the protection level of the equipment, describes the operat-ing conditions and makes it easier to assign permitted equipment to a zone. In additionto the degree of protection (normal, high, very high), the directive distinguishes betweenexplosive G (gas) and D (dust) atmospheres.

Overview of explosion-proof equipmentThe following table describes the division of explosion-proof equipment into equipmentgroups I and II:

Potentially explo-sive atmospheres

Potentially explosive atmospheres are divided into gas and dust. The atmosphere isindicated by the letters G (Gas) and D (Dust) in the designation of the variant.

2 Categories and protection typesProduct Description

Protection types

Validity of the Declaration of ConformityThe declaration of conformity is a statement that a device complies with Directive94/9/EC. The validity of this statement of conformance is bindingly linked to compliancewith the operating instructions supplied with the explosion-proof unit (in particularmaintenance and servicing measures and permitted ambient conditions, e.g. ambienttemperature, unit heating from other customer's equipment). This is necessary foradequate risk minimization. The validity of the declaration of conformity becomes void ifthe specifications for designated use made in the operating instructions no longer apply.The validity of the statement of conformance exclusively refers to the gear unit andmotor types listed in the catalog or in the order confirmation. For customer-specifictypes, it is essential that you contact SEW-EURODRIVE.

2.4 Categories and protection typesCategory 1 Particularly high safety

SEW-EURODRIVE does not provide category 1 gear units and electric motors. Conse-quently, drives from SEW-EURODRIVE cannot be used in zones 0 and 20 where poten-tially explosive atmospheres are to be expected on a continuous and long-term basis.

Category 2 High safetyUnits in category 2 are safe in terms of the expected unit malfunctions and are pre-dominantly intended for use in zones 1 and 21. Of course, these units can also be usedin zones 2 and 22.

Category 3 normal safetyEquipment in category 3 is safe when it is used as intended and overload is predictable.These units are designed for zones 2 and 22.

Categories and protection typesProduct Description

Motors Typical electrical drives of type II2G for zone 1 are motors with the following protectiontypes:

Protection type d flameproof enclosure

The housing is able to withstand the pressure even if an explosion occurs inside themotor. Gas which may escape is sufficiently cooled so it will not ignite a potentiallyexplosive atmosphere outside the motor. This is achieved by ignition gaps, which alsoreduce the pressure that builds up in the event of an explosion.

Protection type e increased safety

No source of ignition is present in normal operation and in the event of a foreseeablemalfunction. This is achieved by design measures such as higher quality insulationsystems or larger clearances. Normal operation is operation including the usual equip-ment malfunctions.The following graph shows a sample temperature profile on a motor with a blocked shaft.The temperature rises from the rated temperature ϑN to the maximum permitted surfacetemperature T3 = 200 °C during the heating time tE.

2 Categories and protection typesProduct Description

A special protective circuit breaker switches off the motor within the motor's heating timetE if a malfunction occurs. This ensures that the critical temperature (here: temperatureclass T3) is not reached.To ensure that the protective circuit breaker (S) reacts reliably according to EN 60079,motors (M) with protection type "e" must at least maintain the heating time tE ratio andthe ratio between starting and rated current (IA/IN) as shown in the following graph (areaabove the characteristic curve). The protective circuit breakers (S) must trip first (areabelow the characteristic curve) to protect the motors against excessive temperature.

Gear units The following protection types apply to gear units:

Protection type c constructional safety

Protection type c (constructional safety c) is achieved through constructional measuresthat provide adequate protection against the possibility of ignition due to hot surfaces,sparks and adiabatic compression caused by moving parts (DIN EN 13463-5).

Protection type k liquid immersion

Protection type k (liquid immersion k) is the protection type in which partial or completeimmersion in a non-flammable, insulating liquid or constant wetting of a potentially com-bustible surface with such a liquid is used to deactivate the potential source of ignitionor to provide separation from the potentially explosive atmosphere (DIN EN 13463-8).

Categories and protection typesProduct Description

Category 3 – normal safetyCategory 3 equipment is only intended for zones 2 and 22 where there is a low proba-bility of potentially explosive atmospheres occurring.

Protection type n Typical electrical drives of the II3G type for zone 2 (gas) are motors with protection typenA – non-sparking. The requirements of protection type n largely correspond to therequirements of protection type e, but for operation without malfunctions.

Protection type t Protection type t is for motors that are to be used in areas with ignitable dusts. The unitsare designated with tb (suitable for zone 21) or tc (suitable for zone 22) according to theequipment category.In this case, explosion protection is realized by safely preventing the ingression of ignit-able dust and the occurrence of impermissibly high temperatures on the surface. For category 3 units with protection type t, a difference is made between:• Non-conducting dust• Conducting dustDepending on the classification of the dust, the units must have a minimum IP rating of• IP5x• IP6x

Gear units Compliance with DIN EN 13463-1 must be guaranteed for gear units. In this category,no particular type of protection is required for gear units.

2.6 General notes on the product descriptionAmbient temperature

Gear units and gearmotors from SEW-EURODRIVE can be operated in a wide ambienttemperature range. The following standard temperature ranges are permitted for fillingthe gear units according to the lubricant table:

The rated data of the gear units and gearmotors specified in the catalog refer to anambient temperature of +40 °C.

Gear units and gearmotors from SEW-EURODRIVE can be operated outside thestandard temperature range if project planning is adapted to ambient temperatures fromas low as up to -40 °C in the intensive cooling range until up to +60 °C. Project planningmust take special operating conditions into account and adapt the drive to the ambientconditions by selecting suitable lubricants and seals.

If the drive is to be operated on a frequency inverter, you must also consider the projectplanning notes of the inverter and take into account the thermal effects of inverter oper-ation.

Installation altitude

Due to the low air density at high installation altitudes, heat dissipation on the surface ofmotors and gear units decreases. The rated data listed in the catalog/price catalogapplies to an installation altitude of maximum 1000 m above sea level. Installationaltitudes of more than 100 m asl must be taken into account for project planning of gearunits and gearmotors.

Power and torqueThe power and torque ratings listed in the catalogs refer to mounting position M1 andsimilar mounting positions in which the input stage is not completely submerged in oil.In addition, the gearmotors are assumed to be standard versions with standard lubrica-tion and under normal ambient conditions.Please note that the motor power shown in the selection tables for gearmotors is subjectto selection. However, the output torque and the desired output speed are essential forthe application and need to be checked.

Speeds The quoted output speeds of the gearmotors are recommended values. You can calcu-late the rated output speed based on the rated motor speed and the gear unit ratio.Please note that the actual output speed depends on the motor load and the supplysystem conditions.

Noise The noise levels of all SEW-EURODRIVE gear units, motors and gearmotors are wellwithin the maximum permitted noise levels set forth in the VDI guideline 2159 for gearunits and IEC/EN 60034 for motors.

Gear units Filled with Permitted standard temperature range

Helical, parallel shaft helical and helical-bevel gear units CLP(CC) VG220 -10 °C to +40 °C

Helical-worm gear units CLP(CC) VG680 0 °C to +40 °C

SPIROPLAN® gear units CLP(SEW-PG) VG460 -10 °C to +40 °C


2 General notes on the product descriptionProduct Description

Paint Gear units, motors and gearmotors from SEW-EURODRIVE are painted with"blue/gray"/RAL 7031 machine paint according to DIN 1843 as standard. Special paintsare available on request.

Note: The standard paints of drives from SEW-EURODRIVE are approved for equip-ment group IIC. The paints can also be used for gas group IIC if no processes causingstrong electrical charges are present.

Surface and corrosion protectionIf required, all gear units, motors and gearmotors from SEW-EURODRIVE can also besupplied with special surface protection for applications in extremely humid and chemi-cally aggressive environments.

WeightsPlease note that all weights shown in the catalogs exclude the oil fill for the gear unitsand gearmotors. The weights vary according to gear unit type and gear unit size. Thelubricant fill depends on the mounting position which means no universally applicableinformation can be given. Refer to "Lubricants" in the "Design and Operating Notes"chapter for recommended lubricant fill quantities depending on the mounting position.For the exact weight, refer to the order confirmation.

Air admission and accessibilityThe gearmotors/brakemotors must be mounted on the driven machine in such a waythat both axially and radially there is enough space left for unimpeded air admission, formaintenance work on the brake and, if required, for the MOVIMOT® inverter. Also referto the notes on the motor dimension sheets in the EXM1 motor catalog.

Multi-stage gear unitsYou can achieve particularly low output speeds by using multi-stage gear units or multi-stage gearmotors. Such a setup requires a helical gear unit or gearmotor on the inputend as a second gear unit. It may be necessary to limit the motor power to match themaximum permitted output torque of the gear unit.

Reduced backlash gear unitsHelical, parallel shaft helical and helical-bevel gear units with reduced backlash areavailable from gear unit size 37. The circumferential backlash of these gear units isconsiderably less than that of the standard versions so that positioning tasks can besolved with great precision. The circumferential backlash is specified in angular minutes[ '] in the technical data. The circumferential backlash for the output shaft is specifiedwithout load (max. 1% of the rated output torque); the gear unit input end is blocked. Forfurther information, refer to chapter "Reduced backlash gear units" on page 95.

General notes on the product descriptionProduct Description

RM gear units, RM gearmotorsRM gear units and RM gearmotors are a special type of helical gear units with anextended output bearing hub. They were designed especially for agitating applicationsand allow for high overhung and axial loads and bending moments. The other data arethe same as for standard helical gear units and standard helical gearmotors. You canfind special project planning notes for RM gearmotors in the "Project Planning for GearUnits/RM gear units" chapter.

SPIROPLAN® right-angle gearmotorsSPIROPLAN® right-angle gearmotors are robust, single- and two-stage right-anglegearmotors with SPIROPLAN® gearing. The difference to the helical-worm gear units isthe material combination of the steel-on-steel gearing, the special tooth meshingrelationships and the aluminum housing. As a result, SPIROPLAN® right-angle gear-motors are wear-free, very quiet and light. The particularly short design and the alumi-num housing make for very compact and lightweight drive solutions.After the running-in period, some sizes of the SPIROPLAN® right-angle gearmotorseries are below the following sound pressure level in 4-pole motor operation on a 50 Hzsupply system:• SPIROPLAN® W..20 to W..30: 55 dB(A)The sound-pressure level may be 3 to 5 dB(A) higher at time of delivery than after hoursof regular operation.The wear-free gearing and the life-long lubrication facilitate long periods of mainte-nance-free operation. The fact that the oil filling is independent of the mounting position,except for SPIROPLAN® W..37 and W..47 in mounting position M4, makes any positionpossible for SPIROPLAN® right-angle gearmotors without having to alter the oil quantity.Identical hole spacing in the foot and face, as well as the equal shaft height to both,provides you with diverse mounting options. Two different flange diameters are avail-able. On request, SPIROPLAN® right-angle gearmotors can be equipped with a torquearm.

Brakemotors On request, motors and gearmotors can be supplied with an integrated mechanicalbrake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coilthat releases electrically and brakes using spring force. Due to its operating principle,the brake is applied if the power fails. It meets the basic safety requirements. The brakecan also be released mechanically if equipped with manual brake release. For thispurpose, the brake is supplied with either a hand lever with automatic reset or an adjust-able setscrew. The brake is controlled by a brake controller that is either installed in themotor wiring space or the control cabinet. A characteristic feature of the brakes is theirextremely short design. The brake bearing end shield is a part of both the motor and thebrake. The integrated construction of the SEW-EURODRIVE brakemotor permitsparticularly compact and sturdy solutions.

2 Extended storageProduct Description

Special protective measuresGearmotor output shafts can be treated with special optional protective measures foroperation subject to severe environmental pollution or in particularly demandingapplications.

NOCO® fluid As standard, SEW-EURODRIVE supplies NOCO® fluid corrosion protection and lubri-cant with every hollow shaft gear unit. Use NOCO® fluid when installing hollow shaftgear units. Using this fluid can help prevent contact corrosion and makes it easier todisassemble the drive at a later time. NOCO® fluid is also suitable for protectingmachined metal surfaces that do not have corrosion protection, such as parts of shaftends or flanges. You can order larger quantities of NOCO® fluid from SEW-EURODRIVE.NOCO® fluid is a food grade substance according to NSF-H1. You can tell that NOCO®

fluid is a food grade oil by the NSF-H1 identification label on its packaging.

2.8 Extended storageType You can also order gear units prepared for "extended storage." SEW-EURODRIVE

recommends the "extended storage" type for storage periods longer than 9 months.In this case, a VCI corrosion inhibitor (volatile corrosion inhibitor) is added to the lubri-cant in these gear units. Please note that this VCI anti-corrosion agent is only effectivein a temperature range from -25 °C to +50 °C. The flange contact surfaces and shaftends are also treated with anti-corrosion agent. If not specified otherwise in your order,the gear unit will be supplied with OS1 surface protection. Instead of OS1, you can orderOS2, OS3 or OS4.

Measure Protection principle Suitable for

Coating on output shaft end Surface coating of the contact surface of the oil seal
