2. HANDLING
2.1 Reception check
Immediately upon receipt check the motor for external damage (e.g. shaft-ends and anges and painted surfaces) and if found, inform the forwarding agent
without delay.
Check all rating plate data, especially voltage and winding connection (star or delta). The type of bearing is specied on the catalogue of all motors.
2.2 Transportation and storage
The motor should always be stored indoors (above –20°C), in dry, vibration free and dust free conditions. During transportation, shocks, falls and humidity
should be avoided. In other conditions, please contact TECHTOP.
Unprotected machined surfaces (shaft-ends and anges) should be treated against corrosion.
It is recommended that shafts are rotated periodically by hand to prevent grease migration.
Anti-condensation heaters, if tted, are recommended to be used to avoid water condensing in the motor.
The motor must not be subject to any external vibrations at standstill so as to avoid causing damage to the bearings.
Motors tted with cylindrical-roller and/or angular contact bearings must be tted with locking devices during transport.
2.3 Lifting
All TECHTOP motors above 25 kg are equipped with lifting lugs or eyebolts.
Only the main lifting lugs or eyebolts of the motor should be used for lifting the motor. They must not be used to lift the motor when it is attached to other
equipment.
Lifting lugs for auxiliaries (e.g. brakes, separate cooling fans) or terminal boxes must not be used for lifting the motor.
Motors with the same frame may have a different center of gravity because of different output, mounting arrangements and auxiliary equipment. Damaged
lifting lugs must not be used. Check that eyebolts or integrated lifting lugs are undamaged before lifting.
Lifting eyebolts must be tightened before lifting. If needed, the position of the eyebolt can be adjusted using suitable washers as spacers.
Ensure that proper lifting equipment is used and that the sizes of the hooks are suitable for the lifting lugs.
Care must be taken not to damage auxiliary equipment and cables connected to the motor.

3. INSTALLATION AND COMMISSIONING
WARNING!
Disconnect and lock out before working on the motor or the driven equipment.
3.1 General
All rating plate values must be carefully checked to ensure that the motor protection and connection will be properly done.
WARNING!
In case of motors mounted with the shaft upwards and water or liquids are expected to go down along the shaft, the user must take in account to mount
some means capable of preventing it.
Remove transport locking if employed. Turn shaft by hand to check free rotation if possible.
Motors equipped with roller bearings:
Running the motor with no radial force applied to the shaft may damage the roller bearing.
Motors equipped with angular contact bearing:
Running the motor with no axial force applied in the right direction in relation to the shaft may damage the angular contact bearing.
WARNING!
For machines with angular contact bearings the axial force must not by any means change direction.
Motors equipped with regreasing nipples:
When starting the motor for the rst time, or after long storage, apply the specied quantity of grease.
For details, see section “5.2.2 Motors with regreasable bearings“.
3.2 Insulation resistance check
Measure insulation resistance before commissioning and when winding dampness is suspected.
WARNING!
Disconnect and lock out before working on the motor or the driven equipment.
Insulation resistance, corrected to 25°C, must exceed the reference value, i.e. 100 MΩ (measured with 500 or 1000 V DC). The insulation resistance value is
halved for each 20°C rise in ambient temperature.
LOW VOLTAGE MOTORS - Installation, operation, maintenance and safety manual - rev. 01 - 1.07.2016

WARNING!
The motor frame must be grounded and the windings should be discharged against the frame immediately after each measurement to avoid risk of electrical
shock.
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 for 12-16 hours
followed by 105°C for 6-8 hours.
Drain hole plugs, if tted, must be removed and closing valves, if tted, must be opened during heating. After heating, make sure the plugs are retted.
Even if the drain plugs are tted, it is recommended to disassemble the end shields and terminal box covers for the drying process.
Windings drenched in seawater normally need to be rewound.
3.3 Foundation
The end user has full responsibility for preparation of the foundation.
Metal foundations should be painted to avoid corrosion.
Foundations must be even, and sufciently rigid to withstand possible short circuit forces. They must be designed and dimensioned to avoid the transfer of
vibration to the motor and vibration caused by resonance.
3.4 Balancing and tting coupling halves and pulleys
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 standard balancing method
specied for the motor.
Coupling halves and pulleys must be tted on the shaft by using suitable equipment and tools which do not damage the bearings and seals.
Never t a coupling half or pulley by hammering or by removing it using a lever pressed against the body of the motor.
3.5 Mounting and alignment of the motor
Ensure that there is enough space for free airow around the motor. Minimum requirements for free space behind the motor fan cover should be achieved.
Correct alignment is essential to avoid bearing, vibration and possible shaft failures.
Mount the motor on the foundation using the appropriate bolts or studs and place shim plates between the foundation and the feet.
Align the motor using appropriate methods.
If applicable, drill locating holes and x the locating pins into position.
LOW VOLTAGE MOTORS - Installation, operation, maintenance and safety manual - rev. 01 - 1.07.2016 9
Re-check the alignment after nal tightening of the bolts or studs.
3.6 Slide rails and belt drives
Fasten the motor to the slide rails as shown in Figure 2.
Place the slide rails horizontally on the same level.
Check that the motor shaft is parallel with the drive shaft. Belts must be tensioned according to the instructions of the supplier of the driven equipment.
WARNING!
Excessive belt tension will damage bearings and can cause shaft damage.
3.7 Cabling and electrical connections
The terminal box on standard single speed motors normally contains six winding terminals and at least one earth terminal.
In addition to the main winding and earthing terminals, the terminal box can also contain connections for thermistors, heating elements or other auxiliary
devices.
Suitable cable lugs must be used for the connection of all main cables. Cables for auxiliaries can be connected into their terminal blocks as such.
Machines are intended for xed installation only. If not otherwise specied, cable entry threads are metric. The IP-class of the cable gland must be at
least the same as those of the terminal boxes.
Unused cable entries must be closed with blanking elements according to the IP class of the terminal box.
The degree of protection and diameter are specied in the documents relating to the cable gland.
WARNING!
Use appropriate cable glands and seals in the cable entries according to the type and diameter of the cable.
Earthing must be carried out according to local regulations before the machine is connected to the supply voltage.
Ensure that the motor protection corresponds to the environment and weather conditions; for example, make sure that water cannot enter the motor or the
terminal boxes.
The seals of terminal boxes must be placed correctly in the slots provided, to ensure the correct IP class.
3.7.1 Connections for different starting methods
The terminal box on standard single speed motors normally contains six winding terminals and at least one earth terminal.
This enables the use of DOL- or Y/D–starting. See Figure 1.
For two-speed and special motors, the supply connection must follow the instructions inside the terminal box or in the motor manual.
LOW VOLTAGE MOTORS - Installation, operation, maintenance and safety manual - rev. 01 - 1.07.2016
10
The voltage and connection are stamped on the terminal box cover.
Direct-on-line starting (DOL):
Y or D winding connections may be used.
For example, 690 VY, 400 VD indicates Y-connection for 690 V and D-connection for 400 V.
WARNING!
from 10KW Start/Delta (Y/D) starting is recommended Star/Delta starting (Y/D):
The supply voltage must be equal to the rated voltage of the motor when using a D-connection.
Remove all connection links from the terminal block.
3.7.2 Connections of auxiliaries
If a motor is equipped with thermistors or other RTDs (Pt100, thermal relays, etc.) and auxiliary devices, it is recommended they be used and connected by
appropriate means.
Maximum measuring voltage for the thermistors is 2.5 V. Maximum measuring current for Pt100 is 5 mA. Using a higher measuring voltage or current may cause
errors in readings or damage the system.
3.8 Terminals and direction of rotation
The shaft rotates clockwise when viewing the shaft face at the motor drive end, and the line phase sequence L1, L2, L3 is connected to the terminals as shown
in Figure 1.
To alter the direction of rotation, interchange any two connections on the supply cables.
If the motor has a unidirectional fan, ensure that it rotates in the same direction as the arrow marked on the motor.
4. OPERATION
4.1 Use
The motors are designed for the following conditions unless otherwise stated on the rating plate.
- Normal ambient temperature limits are -20°C to +40°C.
- Maximum altitude 1000 m above sea level.
