•
Do not put fingers or foreign objects into the opening of the drive unit or reducer; possible electric shock,
personal injury, fire or damage to the equipment may result.
•
•
•
Drive unit or reducer is very hot during operation. Touching the unit may result in burns.
•
Do not loosen the oil filler plug during operation; otherwise, hot, splashing lubricant may cause burns.
•
If a problem occurs during operation, stop operation immediately; otherwise, electric shock, personal injury or
fire may result.
i
•
Do not operate the unit in excess of the name plate rating; possible, personal injury or damage to the equipment
may result.
CAUTION
•
Do not touch rotating parts (output shaft, etc.) during operation; loose clothing may become caught in these
rotating parts and cause serious injury or death.
•
When the power supply is interrupted, be sure to turn off the power switch. Unexpected resumption of power
may cause electric shock, personal injury or damage to the equipment.
•
Do not operate the unit with the terminal box cover removed. Install the terminal box cover after maintenance,
in order to prevent electric shock.
•

DANGER
After the unit is installed, filled with oil and properly wired, check the following before operating:
(1) Is the wiring correct?
(2) Is the unit properly coupled with the driven machine?
(3) Are foundation bolts tightened to the proper torque value?
(4) Is the direction of rotation as required?
When all of the above questions are positive, conduct a trial run with light load. Move on to actual operation after
confirming that are no abnormal sound, vibration, and temperature rise.
Check the items shown in Table 15.
Table 15 Items to Check During Initial Start-up and Break-in Period
•
Paramax drives are shipped without oil. Units must be filled with the proper amount of recommended oil
prior to start-up.
(1)
Is the housing deformed because the installation surface is not flat?
(2) Is insufficient rigidity of the installation base generating excessive
noise?
(3) Is the shaft center aligned with the driven machine?
(4) Is the vibration of the driven machine transmitted to the
gearmotor or reducer?
(1) Is the voltage rise or drop substantial?
(2) Is the ambient temperature too high?
(3) Does the current flowing to the motor exceed the rated
current shown on the rating plate?
(4) Is the oil level specified level?
Do you hear or feel abnormal sound
or vibration ?
Is the surface temperature of the
drive unit
or reducer abnormally
high?
If any abnormalily is found, stop operation and contact our nearest agent, distributor, or sales office.
