  ■ Prevent reconnection.
  ■ Make sure that the equipment is at zero voltage.

■ Ground and short-circuit the terminals.
■ Cover or isolate nearby components that are still live.

To energize the system, apply the measures in reverse order.

Electric motors have hot surfaces, contain live parts and dangerous rotating parts. Fatal or severe injuries and substantial material damage can occur if the required covers are removed or if the motors are not handled, operated or maintained properly.

LIFTING AND STORAGE

Please check the delivered product if any damages can exist in transportation process.

Motors above 25 kg weight have lifting lugs or eye bolts. The actual weight of motors is shown on the nameplate.

■ Only the main lifting lugs or eyebolts of the motor should be used for lifting the motor.
■ Use all the lifting eyes on the motors.
■ Don't use damaged lifting lug.

Shocks, falls, and humidity should be avoided during transportation

During storage, the following conditions must be satisfied.

• The storage rooms must provide protection against extreme weather conditions. They must be dry, free from dust, frost, and vibration, and well ventilated.
  ■ Temperature shall be between -15^ and 40^ .
  ■ Motor shaft shall be rotated by hand at least once per year.
• Protect motors from direct effect of sun and from gases that have corrosion impact on motors.
  ■ Unprotected machined surfaces (shaft-ends and flanges) should be treated against corrosion.
• Open any condensation drain holes to drain the condensation (<6 months).
  If an anti-condensation heater is provided, switch it on during the machine stoppages.

COMMISSIONING

Immediately upon receipt, check the motor for external damage (e.g. shaft-ends and flanges and painted surfaces) and if found, inform the forwarding agent without delay. Check all nameplate data, especially voltage and winding connection to ensure that the motor protection and connection will be properly done.

Checking The Insulation Resistance

Motor winding insulation resistance shall be measured prior to starting the motor, if the winding is too damp.

■ Only appropriately trained personnel may carry out this work.
■ Before starting commissioning, install all covers that are designed to prevent active or rotating parts from being touched.
- If any power cables are connected, check to make sure line supply voltage cannot be connected.
- Once you have measured the insulation resistance, discharge the winding by connecting it to the ground potential.
■ Measurement of insulation resistance should be performed while the motor is not in operation.
If the measurements are performed at winding temperatures not equal to 25 °C , convert the measured value to the reference temperature of 25 °C to be able to compare the values with the table below.
■ The insulation resistance halves every time the temperature rises by 10 °K.
■ The resistance doubles every time the temperature falls by 10 °K .

Insulation resistance, corrected to 25^ C, must be higher than the reference value given below.

If the reference resistance value is not attained, the winding is too damp and must be oven dried.

The oven temperature should be 90^ C - 100^ C for 12 hours.

Insulation Resistance of The Stator Winding at 25 °C
Measuring circuit voltage	500 V
Minimum insulation resistance for new, cleaned or repaired windings	100 MΩ

MECHANICAL INSTALLATION

Safety Considerations

• The machine is intended for installation and use by qualified personnel, familiar with health and safety requirements and national legislation.
  ■ Safety equipment necessary for the prevention of accidents at the installation and operating site must be provided in accordance with local regulations.
• The temperature of the outer casing of the motor may be too hot to touch during normal operation and especially after shut-down.
  ■ Be aware of rotating parts of the motor.
• Do not open terminal boxes while energized.

Before start-up, please check that:

• Condensation drain holes are always located at the lowest point of the motor!
  ■ Connect the motor corresponding to the specified direction of rotation.
  ■ Ensure that all seals and sealing surfaces are undamaged and clean.

When aligning and fastening the motor, please bear the following in mind:

• The motor shall be mounted on a base, which is rigid enough to prevent distortion and vibration.
  ■ Feet and flanges must be fastened securely.
  ■ Avoid using rigid coupling measures.
• The motors must be carefully aligned. Incorrect alignment can lead to beating failure, vibration, even shaft fracture.
• Coupling halves and pulleys must be fitted on the shaft by using suitable equipment and tools which do not damage the bearings and seals. Never fit a coupling half or pulley by hammering or by removing it using a lever pressed against the body of the motor
  ■ Excessive belt tension will damage bearings and can cause shaft damage.
  If a belt drive is used, make sure that the driving and the driven pulleys are correctly aligned.
• The motor should be mounted in such a way that the cooling air should flow to and away from the motor without obstruction.
• Do not exceed permissible loading values for bearings as stated in the product catalogues.

As standard, balancing of the motor has been carried out using half key.

Coupling halves or pulleys must be balanced after machining the keyways. Balancing must be done in accordance with the balancing method specified for the motor.

When aligning the motor to the load, it must be ensured that the couplings used are on the same axis. In addition, at least 2-5 mm axial clearance is required between the couplings.

If the belt pulley system is used when connecting the motor to the load, care must be taken to ensure that the pulleys are in parallel axes and that the belt is not too tight or too loose.

ELECTRICAL INSTALLATION AND OPERATION CONDITIONS

Before installation, check motor specifications from nameplate if they fit the requirements and specification of voltage and frequency.

Measure the insulation resistance between windings and housing.

Note the following safety information before connecting-up the motor:

- Only qualified and trained personnel should carry out work on the motor while it is stationary.

- Disconnect the motor from the power supply and take measures to prevent it being reconnected. This also applies to auxiliary circuits.

■ Check that the motor really is in a no-voltage condition.

■ Establish a safe protective conductor connection before starting any work.

It must be ensured that there are no foreign bodies, dirt, or moisture in the terminal box.

- Keep the inside of the terminal box clean and free from trimmed-off ends of wire.

- Close any additional open cable entries with O-rings or suitable flat gaskets, the terminal box itself must be sealed so that it is dust and watertight using the original seal.

■ When performing a test run, secure the feather keys without output elements.

- Earthing must be carried out according to local regulations before the machine is connected to the supply voltage.

The losses occurring during no-load operation in single phase motors are much more than the losses in nominal load operation. Therefore, single phase motors must not be run no-load for a long time.

Terminals and Direction of Rotation

The standard motors are suitable for clockwise and counterclockwise rotation.

In three phase motor, when the power cables L1, L2, L3 are connected to U1, V1, W1 respectively, the three phase motor shaft turns in clockwise direction (looking at the shaft from drive side). If two of the power cables are interchanged then the resulting direction of rotation is counterclockwise.

In single phase motor, when the power cables L1 and N are connected to U1 and U2 respectively, the single phase motor shaft turns in clockwise direction (looking at the shaft from drive side). If the winding ends (Z1 and Z2) of the auxiliary winding are replaced then the resulting direction of rotation is counterclockwise.

In addition to the main winding terminals and earthing terminal, the terminal box can also contain connections for thermistors, heating elements or other auxiliary devices.

The terminal box on standard single speed three phase motors normally contains six winding terminals and at least one earthing terminal. This enables the use of DOL (direct online) or Y/D (star delta) starting. The standard single-phase motor terminal box contains four winding terminals (two main winding ends and two auxiliary winding ends), two capacitor terminals (CR) and at least one ground terminal.

The three phase motors shall be connected in star or delta according to rated voltage given in their nameplate and the network voltage that they will be connected to. For phase to phase 400 V supply, the motors with 230/400V nameplate values shall be connected in star (Y) and the motors with 400/690V nameplate values shall be connected in delta ( ). The connection types given below should be applied for single-phase motors, depending on the direction of rotation.

Terminal Connection For Single Speed Motor:

U1 W2 U2 V2 U1 V1 W1 L1 L2 L3 Star Connection

U1 W1 V1 Delta Connection W2 U2 V2 U1 V1 W1 L1 L2 L3

Faults During Operation

Deviations from conditions during normal operation, such as an increase in power consumption, temperatures or vibrations, unusual noises or odours, tripping of monitoring devices, etc., indicate that the motor is not functioning properly. This can cause faults which can result in eventual or immediate death, severe injury, or material damage.

■ Immediately inform the maintenance personnel.
- If you are in doubt, immediately switch off the motor, being sure to observe the system-specific safety conditions.

INSPECTION

Safety Instructions

■ Before starting work on the motors, make sure that the plant or system has been disconnected in a manner that is compliant with the appropriate specifications and regulations.
In addition to the main currents, make sure that supplementary and auxiliary circuits, particularly in heating devices, are also disconnected.
- A motor with frequency converter supply may energize even if the motor is at standstill.
- Certain parts of the motor may reach temperatures above 50°C. Physical contact with the motor could result in burn injuries! Check the temperature of parts before touching them.

General Inspection

Inspect the motor at regular intervals, at least once a year. The frequency of checks depends on, for example, the humidity level of the ambient air and on the local weather conditions. This can initially be determined experimentally and must then be strictly adhered to.

Keep the motor clean and ensure free ventilation airflow. If the motor is used in a dusty environment, the ventilation system must be regularly checked and cleaned.

• Check the condition of shaft seals and replace if necessary.
• Check the condition of connections and mounting and assembly bolts.
• Check the bearing condition by listening for any unusual noise, vibration measurement, bearing temperature, inspection of spent grease.
• Check if the electrical parameters are maintained.
• Check if the winding insulation resistances are sufficiently high.
• Check if the cables and insulating parts and components are in a good condition and are not discoloured.

Immediately correct any impermissible deviations that are determined in the inspection.

If the paint is damaged, it must be repaired to protect the unit against corrosion.

Pay special attention to bearings when their calculated rated lifetime is coming to an end.

When signs of wear are noticed, dismantle the motor, check the parts, and replace if necessary. When bearings are changed, replacement bearings must be of the same type as those originally fitted. The shaft seals must be replaced with seals of the same quality and characteristics as the originals when changing bearings.

MAINTENANCE AND REPAIR

Cleaning

Regularly clean the cooling air passages through which the ambient air flows, e.g. using dry compressed air.

Particularly when carrying out cleaning using compressed air, make sure you use suitable safety wear.

If there are condensate drain holes present, these must be opened at regular intervals, depending on climatic conditions. To maintain the degree of protection, any condensation drain holes need to be closed.

Instructions for Repair

Only appropriately qualified persons should be deployed to commission and operate equipment. Qualified persons, as far as the safety instructions specified in this manual are concerned, are those who have the necessary authorization to commission, ground and identify equipment, systems and circuits in accordance with the relevant safety standards.

Before you begin working on the three-phase motor, in particular before you open the covers of active parts, make sure that the three-phase motor or system is properly isolated from the supply.

Replacing Bearings

Special care should be taken with the bearings. These must be removed using pullers and fitted by heating or using special tools for the purpose.

Do not reuse bearings that have been removed.

Rewinding

Rewinding should always be carried out by qualified repair shops.

Assembly

If possible, assemble the motor on an alignment plate.

Avoid damaging the windings protruding out of the stator enclosure when fitting the end Shield Take care not to damage the cable jacket. Tightening torques must be adapted to suit the type of cable jacket material in use.

Shaft sealing should be assembled to the right position without any damage.

• Check the terminal box seals and if required, replace.
• Do not forget the foam cover in the cable entry (seal all holes completely and prevent cables from touching any sharp edges).
  ■ Repair any damage to the paint (also on screws/bolts).
• Check the tightening torques of all screws, as well as those of screws which have not been unscrewed.

DISPOSAL

Dismantle the motor using the general procedures commonly used in mechanical engineering. Dispose of the separated components according to local regulations or via a specialist disposal company.
