Safety Precautions
Caution
Don't put an object or finger into the motor
opening.
Don't turn off and on power so frequently.
Don't pull leadwires with an excessive force.
Don't use the equipment in highly intensive
electric field.
Don't use the equipment under direct sunshine.
Don't use the equipment in an environment where
electro-static voltage potentials may be produced.
Don't drop or cause topple over of something
during transportation or installation.
Never attempt to perform modification,
dismantle or repair.
Perform installation by taking into
consideration the mass of the body and rated
output of the product.
Adjust the motor ambient environmental
condition to match the motor operating
temperature and humidity.
Exactly follow the installing method and
direction specified.
Connect a ground-fault interrupter, circuit breaker
and replay to the brake control relay in series so
that they are turned off upon emergency stop.
Test-run the securely fixed motor without
loading to verify normal operation, and then
connect it to the mechanical system.
Level of input voltage to peripheral devices
should correspond to the motor rated voltage.
Provide protection device against idling of
electro-magnetic brake or gear head, or
grease leakage from gear head.
Don't place any obstacle object around the
motor and peripheral, which blocks air passage.
Correctly run and arrange wiring.
Maintenance must be performed by an
experienced personnel.
Always keep power disconnected when the
power is not necessary for a long time.
Please observe safety precautions fully.

be handled by experienced personnel familiar with the product.
<note>
When export this product, follow statutory provisions of the destination country.
Unpacking
• Proceed as follows:
• First open the top of the packing and check the units for damage in transit.
• Check the motor nameplate for the model number, output, No. of poles, voltage, frequency,
etc.
Do not use the product if it does not meet your specification (if you dare to use it, burn
injury or fire may result).
• A single-phase motor comes with capacitor and capacitor cap. Check the rated capacitance
and voltage on the nameplate. Do not use the accessory capacitor if it does not meet your
specification (if you dare to use it, you may be injuried or may have fire).
• Gear head is optional.
• Check a gear ratio on the nameplate. Do not use it if it does not meet your specification (if you
dare to use it, you may be injuried or may have fire).
Should you find any discrepancy in the product, consult your local dealer.
Scraps must be treated as industrial waste.
