2.6

Explosion hazard from hybrid mixtures

Explosion hazard from hybrid mixtures
Hybrid mixtures are mixtures of flammable dusts with explosive gas/air atmospheres which can together create a dangerous explosive atmosphere if they occur at the same time. Changes can arise in the safety performance characteristics here, such as a change in the zonal classification, increase in the explosion pressure, reduction in the minimum ignition energy and a reduction in the maximum temperatures to be complied with.
An explosion can occur. This can result in death, serious injury or material damage.
· As a consequence, when hybrid mixtures occur, carefully observe the relevant parameters both for gas (Zones 0, 1 and 2 or Class I) as well as also for dust (Zones 20, 21 and 22 or Class II). It is necessary for a competent assessing body to determine in individual cases whether the parameters determining ignition are unfavorably influenced in a particular hybrid mixture.
· Motors with dual plates for G “Gas” and D “Dust” or Class I and Class II may only be used where these two occur after prior careful examination of the properties of the hybrid mixtures by the user.
· These explosion-protected machines are not suitable for hybrid explosive environments. Use in atmospheres where there is a risk of explosion caused by both gas and dust simultaneously is absolutely prohibited.

3.3.2

Cooling and ventilation
The machines of this series are three-phase induction machines with a closed primary (internal) cooling circuit and an open secondary cooling circuit (surface cooling). The surface cooling varies depending on the version.

3.3.2.1

Machines with a fan

Self-ventilation (standard): Cooling method IC 411 according to EN / IEC 60034-6
Located at the ND end of the stator housing is an air intake cowl that guides the external air on its way to the motor. The external air is drawn in through openings in the air intake cowl and flows axially across the outer cooling ribs of the motor frame. The fan wheel for the external flow of cooling air is attached to the machine shaft. The fan wheels are bidirectional. Check the cooling effect below rated speed in the case of frequent switching or braking ­ or if the speed is controlled continually below the rated speed.

Forced ventilation (optional): Type of cooling IC 416 in accordance with EN / IEC 60034-6
Cooling that does not depend on the speed is achieved by means of a unit that is independent of the motor operating state (forced ventilation). This unit is closed to the outside by a fan cover. It has its own main drive with fan impeller which creates the cooling air flow required for cooling the motor.

3.3.2.2

Machines without a fan (optional)
Cooling method IC 410 Surface cooling by free convection: Cooling method IC 410 according to EN / IEC 60034-6
Cooling method IC 418 Surface cooling by relative movement of cooling air: Cooling method IC 418 according to EN / IEC 60034-6

Description 3.3 Installation

3.3.3

Bearings
To support the machine shaft and maintain its position in the non-moving part of the machine, DE and NDE rolling bearings are used. One end performs the function of a locating bearing that transfers axial and radial forces from the rotating machine shaft to the nonmoving part of the machine. The opposite end is implemented as a floating and support bearing to allow thermal expansion inside the machine and transfer radial forces. The nominal (theoretical) service life of the bearings according to ISO 281 is at least 20,000 hours when the permissible radial/axial forces are complied with, and the machine is operated on 50 Hz line supplies. However, the achievable useful life of the bearings can be significantly longer in the case of lower forces (e.g. operation with self-aligning couplings).
Rolling bearings with permanent lubrication are maintenance-free.

3.3.4

Axial and radial forces
Permissible values for axial and radial forces are listed in the catalog or stamped on the rating plate depending on the type of construction / mounting type. The data stamped on the rating plate have priority.
WARNING
Damage to bearings or the shaft
Large output masses and their centers of gravity outside the shaft extensions can lead to resonance in operation. This can result in damage to the bearings and shaft. In an explosive atmosphere, there is a risk of explosion. Death, serious injury, or material damage can result. · Ensure that the permissible loads for the forces on the shaft extension are adhered to in
accordance with the catalog data or configuration data. · Under all circumstances, maintain the minimum radial load of cylindrical rolling bearings
of 50 % of the permissible radial force.
The machine is equipped with grease-lubricated rolling bearings.
· In the standard version, the bearings of machines up to shaft height 250 are permanently lubricated.
· The bearings of machines from shaft height 280 and above are equipped with a relubrication system.

3.3.5

Balancing
As standard, the machine is designed with vibration severity level A. The rotor is dynamically balanced with a half feather key (code “H”). Vibration severity level B can be ordered as option, and stamped on the rating plate.

Storage

Storing outdoors

NOTICE
Damage to the motor
Damage can occur if incorrectly stored.
Take all precautions to protect the motor under extreme climatic conditions, e.g. salt-laden and/or dusty, moist/humid atmospheres.
Choose a dry storage location which is safe from flooding and free from vibration. Repair any damage to the packaging before putting the equipment into storage if this is necessary to ensure proper storage conditions. In order to ensure protection against ground moisture, locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent equipment from sinking into the ground. Do not impede air circulation under the stored items.
Covers or tarpaulins used to protect the equipment against the weather must not come into contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air can circulate freely around the equipment.

Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost and vibration and well ventilated.

Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated with an anti-corrosion agent which will last for a limited amount of time (<6 months). Apply suitable anti-corrosion measures for longer storage times.

4.5.3

Temperature limits during storage
The materials used are specially designed for the temperature range required by the customer. The relevant temperature limits are specified on the rating plate.

WARNING
Risk of explosion due to damaged sealing materials
Storing machines at temperatures that do not fall within the specified limits can damage the material of the seals and cause them to no longer seal correctly. The certified type of protection of the machine can no longer be complied with.
As a result, a potentially explosive gaseous atmosphere can enter the machine and be ignited during commissioning. Explosions can occur. This can result in death, serious injury or material damage. · Do not store the machine in conditions that lie outside the specified temperature limits.

Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the ambient temperature in the operating state or the installation altitude, other conditions could apply regarding the storage temperature. In this case, refer to the machine rating plate for data on the ambient temperature and installation altitude.

Storage time

Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the useful life of the bearing grease (aging).
Open bearings
· For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12 months.
· Replace the grease if it is identified that the grease has lost its lubricating properties or is polluted. The consistency of the grease will change if condensation is allowed to enter.
Closed bearings
· For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.

4.5.4

Securing the rotor
Depending on the version, the machine is fitted with a rotor shipping brace. This protects the bearings against damage due to shock and vibration during transport or storage.
NOTICE
Motor damage due to vibrations
Not using the rotor shipping brace can cause damage to the machine if it is jolted during transport or storage. Material damage can result. · If the machine is fitted with a rotor shipping brace, this should always be used when
transporting the machine. The rotor shipping brace must be attached during the transport. · Protect the motor against strong radial shocks and vibration when storing, as the rotor shipping brace cannot completely absorb these forces. · Do not remove the rotor shipping brace until you are ready to push on the output element. · If the customer already has mounted parts, such as a coupling or belt pulley, the bearings can be damaged during transport. In this case, make sure that the customer uses a rotor shipping brace. · For machines with a vertical type of construction: ­ Do not remove the rotor shipping brace until the machine is in a vertical position. ­ If a machine has to be transported in a horizontal position, the rotor must be fixed in
position before the machine is turned onto its side. Vertical machines can be supplied in the horizontal position from the manufacturing plant.

Insulation resistance and polarization index
Measuring the insulation resistance and polarization index (PI) provides information on the condition of the machine. It is therefore important to check the insulation resistance and the polarization index at the following times: · Before starting up a machine for the first time · After an extended period in storage or downtime · Within the scope of maintenance work The following information is provided regarding the state of the winding insulation: · Is the winding head insulation conductively contaminated? · Has the winding insulation absorbed moisture? From this, you can determine whether the machine needs commissioning or any necessary measures such as cleaning and/or drying the winding: · Can the machine be put into operation? · Must the windings be cleaned or dried? Detailed information on testing and the limit values can be found here: “Testing the insulation resistance and polarization index” (Page 68)
Lubricating the rolling bearings
If you correctly store the machine for a longer period of time, it can be assumed that within a period of 2 years, the grease in the bearings will not deteriorate. · For motors with thermal class 155, for normal ambient temperatures, use a lithium-soap
rolling bearing grease with a dropping point of at least 180 °C. · For machines with thermal class 180, and for certain special machines, use the special
grease specified on the machine lubricant plate.
Regreasing rolling bearings after storage periods of up to two years
· For machines with regreasing systems, briefly lubricate both bearings after commissioning with the machine running as a precautionary measure.
· Grease type, grease quantity and relubrication intervals for the regreasing system are stamped on the rating plate attached to the machine.
Releasing the rotor shipping brace before commissioning
If one is being used, release the rotor shipping brace before commissioning.

Preparing for use 4.14 Converter operation
Note Converter · If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures, manufacturer). · Avoid that the specified limit values stipulated for the drive system (consisting of the motor and converter) are exceeded. · You must observe the EMC information from the manufacturer of the converter. · The most effective method of shielding is to conductively connect a shielded machine supply cable to the metal terminal box of the machine (with a metal screw connection) over a large surface area. · On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused by the converter may occur on the sensor cable.
When used in accordance with their proper and intended purpose and operated on an electrical supply system with characteristics according to EN 50160, the enclosed machines comply with the requirements of the EC Directive regarding electromagnetic compatibility.
Immunity to interference
The machines fulfill the requirements of interference immunity in conformity with EN / IEC 61000-6-2. For machines with integrated sensors, e.g. PTC thermistors, the operating company must ensure sufficient interference immunity by selecting a suitable sensor signal cable (possibly with shielding, connected in the same way as the machine feeder cable) and a suitable evaluation unit. When operating the machines from a converter at speeds higher than the rated speed, carefully comply with the mechanical speed limits (safe operating speed EN / IEC 60034-1).

Parameterizing the converter
· If the design of the motor requires connection to a particular converter type, the rating plate will contain corresponding additional information.
· Correctly parameterize the converter. Parameterizing data can be taken from the machine rating plates. You can find parameter data here:
­ In the converter operating instructions
­ In the TIA selection tool
­ In the SINAMICS Configuration Manual if available
­ For explosion-proof machines, also in the declaration of compliance with the order 2.1.

Preparing for use 4.14 Converter operation
· Do not exceed or fall below limit speed nmin or nmax. If no other value is specified, the minimum speed limit is nmin 5 Hz. The speed limits are either stamped on the rating plate or the supplementary plate for converter operation as the highest or lowest specified speed.
· Carefully check that it is guaranteed that the machine is cooled when it is being commissioned.

4.14.2

Converter input voltage
The insulation system of SIMOTICS LV machines always complies with the requirements of stress category C (IVIC C = high stress). If voltage peaks higher than those specified according to IVIC C can occur, contact the Service Center (Page 12).
· For a line supply voltage (converter input voltage) up to max. 480 V, and when controlled from a SINAMICS converter with uncontrolled/controlled infeed: Comply with the guidelines for configuring motor and converter.
· For line voltages (converter input voltages) higher than 480 V, motors have an appropriate insulation system when ordered for converter operation.
· Operation with a converter from another manufacturer: Comply with the permissible voltage peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the particular line voltage (converter input voltage) and the motor insulation system.
NOTICE
Material damage caused by an excessively high supply voltage
The insulation system will be damaged if the supply voltage is too high for the insulation system. This can completely destroy the machine. · Comply with the peak voltages as laid down in the guidelines above.

4.14.3

Reducing bearing currents
To prevent damage due to bearing currents, you must carefully assess the complete system, i.e. the motor, converter and driven machine.
· In addition to grounding the motors via the solid grounding conductor, use low impedance grounding in the high frequency range using braided flat copper straps or RF stranded wire conductors. Connect these conductors through a large contact surface. Solid copper cables are not suitable for RF grounding because of the skin effect.
· Use symmetrically structured, shielded connecting cables to connect the motor to a converter. The protective braided shield, comprising many strands, must have a high electrical conductivity. Braided shields made of copper or aluminum are well suited. Connect the shielding at both ends on the motor and on the converter. Keep unshielded cable ends short.

Concentric copper or aluminum shield

Steel armor

· To ensure that high-frequency currents are appropriately discharged, establish a contact through the largest possible surface area at both ends. Establish a 360° contact of the cable shielding on the motor enclosure and on the protective grounding bar of the converter, for example, as follows:

­ Motor side: EMC glands at the cable entries

­ Converter side: EMC shield clips

· In the overall system, set up a properly meshed grounding system with low impedance for high-frequency currents.

· No potential difference between the motor, converter, and working machine.

­ Use equipotential bonding cables between the terminal box and the high- frequency grounding point on the motor enclosure.

­ Use a separate high-frequency equipotential bonding cable between the motor enclosure and the protective grounding bar of the converter.

­ Use a separate high-frequency equipotential bonding cable between the motor enclosure and the driven machine.

· Use the common-mode filter (damping cores) at the converter output. The SIEMENS sales partner is responsible for selecting and dimensioning.

· Limit the rise in voltage by using output filters. Output filters dampen the harmonic content in the output voltage.

· Use the motor reactors.

· Preferably use an IT line supply with an insulated neutral point.

The operating instructions for the converter are not part of this documentation. Carefully comply with the instructions in the converter configuring information.
