INSTRUCTIONS FOR HANDLING, INSTALLATION AND MAINTENANCE
1. HANDLING AND STORAGE
Motors should be preferably stored in their normal operating positions. They should be stored in surroundings as
clean and dry and free from vibration as possible.
If motors have been exposed to moisture during long periods of storage then the insulation resistance of the
windings against the frame (earth) should be checked with the aid of a megger (max. d.c. voltage 500V) prior to
installation.
If any motor damage is to be claimed as “warranty”, TECO Australia must be consulted prior to any work being
carried out on motor.
2. INSTALLATION AND OPERATION
Motors should be installed to the requirements of AS3000:2000 SAA Wiring Rules
The installation of the equipment shall be carried out in a manner that does not reduce the protection afforded by
the equipment design.
When installing the motor the following points should be carefully checked:
• rated voltage and frequency
• ambient temperature should not exceed 40°C, unless confirmed with TECO sales office
• altitude does not exceed 1000 meters above sea level
• correct connection of motor (see below)
The use of the motor should conform to the specified degree of protection in accordance with AS1939.
Care must be taken to ensure that the cooling air can flow in and out unhindered. The space between the air
intake and the nearest wall should be approximately equal to the shaft height of the motor. Foundations must be
designed in such a way that vibration is avoided when the motor and the driven machine are running coupled.
Care should be taken to ensure that any condensate drain plugs are located at the lowest point of motor casing.
Before mounting the transmission parts, the motor shaft should be cleaned with a solvent.
Secure motor to a level surface. Unevenness leads to mechanical deformation of the motor. The motor should be
used only with coupling systems, which are elastic with respect to centre offset, angular displacement,
longitudinal shift and torsional strain. Rigid coupling systems are not permissible (unless previously agreed).
If direct coupling is employed check centre offset and angular offset with screwed on test arm and dial gauge.
The following deviations should not be exceeded:
• Centre offset (radial measurement) 0.03 mm in 2 pole motors. 0.05 mm in motors with more than 2
poles. (the dial shows twice the value of the deviation).
• Angular offset (axial measurement) 0.10 mm.
Check alignment at normal operating temperature.
With applications involving belt transmission, unnecessary axial forces on the bearings can be avoided by
positioning the shafts parallel to each other and keeping the pulleys perfectly aligned. The belt tension should be
just sufficiently stretched to prevent slipping in service. If the pulleys are too small the motor shaft is likely to bend
and this must be avoided.
2) CONNECTION DIAGRAMS
This connection is indicated on the connection diagram inside terminal box lid and as shown on page3.
For special voltages and the like, different connections will be noted on the motor nameplate beside voltage.
All Motors are suitable for operation in both directions.
