SAFETY WARNINGS AND PRECAUTIONS
1. Voltage, frequency and the wiring style should be consistent with the
motor nameplate, power supply voltage should be maintained at plus or
minus 5% of the rated operating range.
2. No more than 1000 meters above sea level.
3. Ambient air temperature not exceeding 45 ℃.
4. The motor must have a good grounding device
5. Before option must measure 500-volt megohm table winding insulation
resistance to ground, and its value should be more than 0.2 megohm, or to
be dried.
6. Before starting pull action shaft, it should be flexible rotation, no friction
and collisions, running should be smooth and lightly, without stagnation
and the noise, if found the strange noise, overheating, burning smell,
smoke or slow speed of the phenomenon, should immediately turn off
power, shutdown inspection, repair it.
7. The surrounding environment should keep clean and dry and well
ventilated.
8. When the motors are not allowed backward in the slow, not frequent
start, Capacitor-running motors can not be long-term light-load use.
9. Bearing grease should be changed every six months, to fill the bearing
chamber is about 60% of the gap is appropriate.
10. Check whether the motor fastening is fasten.
11. Check whether the turn is right, if don’t, then in accordance with the
following methods of grafting. (A. the introduction of three-phase line can
be any swap 2. B. any swap the main section of single-phase winding
circumstances leading to side can help.)
12. According to the rated motor power continuous operation, the heating
part of the maximum permissible temperature rise shall not exceed the
following requirements.
13. Winding Temperature: 75 ℃Core: 75 ℃Rolling: 55 ℃.
14. This series of motors using environment and conditions: can be used
in wet dusty place, but should always pay attention to cleaning and
inspection to prevent the extended, dust, iron and other foreign body
broken motor interior.
15. Motor routine maintenance:

- 3 -
Electrical outlet box part of the electrical contacts should be kept
clean and good contacts, whether the motor air inlet plug, so as not to
affect the motor life. Regular maintenance should be a half a year,
check the motor remove dust and oil, grease and abrasion.
16. The motor running check:
When motor is operated it should always be paid attention to whether
the load data in current with requirement, whether the bearing has
phenomena of heat and leakage, if found abnormal or sound, should
be stopped immediately for inspection. Until fault is identified, do not
do Starting test.

COMMON PROBLEMS AND REMEDIES
Problem 1:
When you receive the motor, please check whether the front shaft of the
motor can rotate. if you find that manual rotation is not possible.
Solution:
The concentricity of the motor may be damaged during transportation. You
can hammer the shaft, front end cover and back end cover with a wooden
hammer or a rubber hammer to adjust the concentricity. Until the shaft of
the motor can be turned flexibly manually.
Problem 2:
The motor does not work when it is powered on.
Solution:
1) Please check the power supply to make sure the output voltage is
correct.
2) Please check the wiring carefully to make sure it's the same as the
wiring diagram.
3) Please press the red protector button, hear the clear "click" reset sound,
then reconnect the power, start the motor.
Problem 3:
After the motor is powered on, it rotates slowly and cannot be started
normally.
Solution:
1) Please check the power supply to make sure the output voltage is
correct.
2) Please check the wiring carefully to make sure it's the same as the
wiring diagram.
3) Check the capacitance of the motor to ensure that the capacitance is in
good condition.
Problem 4:
After running for a period of time, the motor heats up and stops working.
Solution:
Motor overloaded running, protector function. After half an hour of cooling,
press the red protector button to reset and try again.
