Safety information Compact Operating Instructions Information for those responsible for the plant or system This electric machine has been designed and built in accordance with the specifications contained in standards EN / IEC 60034 and EN / IEC 60079, and is intended for use in industrial plants and systems. Please observe the country-specific regulations when using the electric machine outside the European Community.
The five safety rules For your own personal safety and to prevent material damage when carrying out any work, always observe the safety-relevant instructions and the following five safety rules according to EN 50110-1 "Working in a voltage-free state". Apply the five safety rules in the sequence stated before starting work. Five safety rules 1.
• It is forbidden for people with pacemakers to enter the vicinity of the machine. • Protect the personnel working in the plant by taking appropriate measures, such as erecting identifying markings, safety barriers and warning signs and giving safety talks. •...
Electrostatic sensitive devices Material damage due to electrostatic discharge Electronic modules contain components that can be destroyed by electrostatic discharge. These components can be damaged or destroyed if they are not handled correctly. To protect equipment against damage, follow the instructions given below.
Risk of explosion due to electrostatic discharge Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges can occur, for example as a result of mechanical friction, flowing air that contains particles - or persons that are not appropriately grounded, e.g. when carrying out maintenance or cleaning work. In an explosive atmosphere, there is a risk of an explosion.

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. The materials used are specially designed for the temperature range required by the customer.
Page 73
NOTICE Storage The motor can be damaged if you use it or store it unprotected outdoors. • Protect the motor against intensive solar radiation, rain, snow, ice and dust.

damage parts mounted by customers, such as cables manufactured out of materials that are not heat resistant. • Temperature-sensitive parts must not come in contact with or be attached to components mounted on the machine. • Only use heat-resistant mounting parts. The connecting cables and cable entries must be suitable for the particular application.

5. Read out the insulation resistance one minute after applying the measuring voltage. Limit values for the stator winding insulation resistance The following table specifies the measuring voltage and limit values for the insulation resistance. These values correspond to IEEE 43-2000 recommendations.
Page 85
• Dry, new windings have an insulation resistance of between 100 and 2000 M Ω , or possibly even higher values. An insulation resistance value close to the minimum value could be due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and other characteristics affect the insulation resistance and may need to be taken into account when determining measures.

3.4.2.3 Aligning the machine to the driven machine and mounting (IM B5, horizontal flange) The standard flange is provided with a centering. The choice of fit for the mating flange on the driven machine is the system manufacturer's or the plant operator's responsibility.
Page 93
1. Grease the centering flange with assembly paste to make the process easier. 2. Screw in two studs into tapped holes on opposite sides of the driven machine flange. The studs act as positioning aids. 3. Lower the machine slowly toward the driven machine and into the centering, so that the flanges do not quite touch.

WARNING Risk of explosion due to excessive temperature rise If the end of the conductor is not correctly enclosed by the end sleeve, but is trapped by it, this can lead to overheating. The temperature class of the machine can be exceeded. This can trigger ignition of an explosive mixture.
4.7.1 Connecting explosion-proof machines to the converter WARNING Machine overheating Operating explosion-protected machines at the converter without using the appropriate protective equipment can result in death or severe injury. Always use PTC thermistor monitoring when operating explosion-protected machines at the converter. Tripping units according to Directive 2014/34/ EU ("Explosion Protection Directive") are always necessary when using PTC thermistor monitoring.

Start-up Check before start-up Once the system has been correctly installed, you should check the following prior to commissioning: Note Checks to be carried out prior to commissioning The following list of checks to be performed prior to commissioning does not claim to be complete.
Page 114
Checks before the first test run Before the first test run, carry out the following checks: • The external fan is correctly fitted and aligned. • The rotor runs freely. • All of the retaining elements and electrical connections are securely tightened.

NOTICE Thermal overload of motors connected directly to the line supply In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by the moment of inertia to be accelerated. While ramping up when connected to the line supply, the inrush (starting) current is a multiple of the rated current.
Operation Safety 6.1.1 Safety instructions during operation Switching on the machine DANGER Hazardous voltages Electrical machines are at hazardous voltage levels. Contact with these can result in death, serious injury or material damage. Operating the machine on a line supply system with a non- grounded neutral point is only permitted for short periods of time that occur rarely, e.g.
Page 118
WARNING Faults in operation Changes with respect to normal operation indicate that there is an impaired function. This can cause faults which can result in eventual or immediate death, severe injury or material damage. For instance, observe the following signs that could indicate a malfunction: •...
Page 119
6.1.2 Hybrid mixtures DANGER 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 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 observed.
Page 120
WARNING Risk of explosion due to excessive bearing temperature The surface temperature cannot be maintained within maximum permissible limits if the bearing becomes too hot. The dust can ignite, resulting in an explosion. This can result in death, serious injury or material damage.
6.1.6 Switching off the anti-condensation heating when the machine is switched on Excessively high machine temperature when heating is switched on If the anti-condensation heating is operated while the machine is running, this can increase the temperatures inside the machine. Material damage can result. •...

(* ) You can perform these checks while the motor is at standstill or, if required, while running. • Further checks may be required if so specified in operating instructions of components or in accordance with the plant-specific conditions. • If you find any deviations during the inspection, you must rectify them immediately.
Page 129
NOTICE Machine damage When carrying out the inspection, if you detect any impermissible deviations from the normal state, you must rectify them immediately. They may otherwise cause damage to the machine. 7.1.5 Assessing the rolling bearings To assess the rolling bearings, it is generally not necessary to dismantle the machines.

• Rolling bearing service life – Replace the rolling bearings once the nominal service life is reached. Alternatively, you can verify they are free of mechanical damage as part of an inspection. – In the case of rolling bearings without a regreasing system, it is ensured that the nominal service life will only be achieved clearly after achievement of the service life of the grease in the bearings.

7.1.8.2 Explosion hazard due to increased surface temperature WARNING Explosion hazard due to increased surface temperature Components within the motor may be hotter than the maximum permissible surface temperature for the enclosure. In an explosive atmosphere, dust can ignite and an explosion occur. This can result in death, serious injury or material damage.
