4.3 Instructions for motor operation

1. The ambient environment for motor is below 1000m, with temperature from -15°C to 40°C
2. The user should provide the power supply with stable voltage( single phase or
three-phase) corresponding to motor, especially for three-phase, every phase must be same
without failure, otherwise, the motor will be burned.
3. Wire connection
pay more attention to safetyand reliability of connection, no failure and wrong connection i
s allowed( especially for three-phase)
Virtual connection: the wire screw is not tightened or dropped.
Phase-losing connection: two phases are connection, the remaining phase is disconnected.
4. The motor should be installed at the dry place where is waterproof and dustproof with good
ventilation and heat dissipation condition.
5. Under normal working condition, the motor needs to be maintained at least one year, with main
maintenance on external cleaning of motor ( including internal fan cover, fan leaf surface and
surface of external housing ventilated rib), if the working condition is harsh ( outdoor or more dust),
the periodical maintenance time should be shortened( half an year, three month or even shorter)
6. The connecting wire between motor and power supply should be checked yearly for aging. In
terms of motor selection, under rated voltage, the torque should be corresponding to its related
equipment, not exceeding the rated torque; otherwise, the shaft of motor might be broken or
burned.
7. The motor must connect to grounding to avoid creepage, causing injury of person.
8. Handle and store carefully the motor.
9. The gearbox is closely connected to the motor, so the collision with motor can lead to loose
connection between motor and gearbox, which will reduce their life. Make sure good ventilation to
avoid overheating of motor.
10. Some simple solutions for motor troubles

1) Connection for 110V and 220V: the yellow and green
wires are connected to the earth, and the black and red
wires are connected to the live line and the neutral line. The
rotation of motor has no effect on operation of pump.
2) Connection for 380V: the yellow and green wires are
connected to the earth, and the other three wires are
connected to the power supply wire. The rotation of motor
has no effect on operation of pump.
Connecting the motor to power supply, the user should
1. Check if the connection between switch and stator
winding is correct
2. Check if the terminal is loose
3. Check if the wire is broken or has virtual connection,
use multimeter to check.
4. Check if starting device is connected correctly.
