1. Safety precautions
When using the electromagnetic brake motor in a vertical drive application such as elevating
equipment, be sure to check the load condition suciently before operating. If a load exceeding the
rated torque is applied or the small torque limiting value is set, the load may fall. This may result in
injury or damage to equipment.
Only qualied and educated personnel should be allowed to perform installation, connection,
operation and inspection/troubleshooting of the product. Handling by unqualied and uneducated
personnel may result in re, electric shock, injury, or damage to equipment.
The motor is ClassⅠequipment. When installing the motor, ground the Protective Earth Terminal of
the motor. Failure to do so may result in electric shock.
Use a motor and driver only in the specied combination. An incorrect combination may cause re,
electric shock, or damage to equipment.
Always turn o the power before performing maintenance or inspection. Failure to do so may result
in electric shock.
Do not use the motor beyond the specications. Doing so may result in re, electric shock, injury, or
damage to equipment.
Do not touch the motor during operation or immediately after stopping. The surface of the motor is
hot and it may cause a skin burn(s).
Do not leave anything around the motor that would obstruct ventilation. Doing so may result in
damage to equipment.
Do not lift the motor by holding the output shaft or the cable. Doing so may result in injury.
Do not touch the motor output shaft (shaft end or pinion section) with bare hands. Doing so may
result in injury.
When assembling the motor with the gearhead, exercise caution not to pinch your ngers or other
parts of your body between the motor and gearhead. Injury may result.
When installing the motor in equipment, exercise caution not to pinch your ngers or other parts of
your body between the product and equipment. Injury may result.
Do not touch the rotating part (output shaft) during operation. Doing so may result in injury.
Securely install the motor on the mounting plate. Improper installation may cause the motor to come
loose and fall, resulting in injury or damage to equipment.
Provide a cover over the rotating part (output shaft). Failure to do so may result in injury.
Securely install a load on the output shaft. Failure to do so may result in injury.
Be sure to ground the motor and the driver to prevent damage from static electricity. Failure to do so
may result in re or damage to equipment.
The motor surface temperature may exceed 70 °C (158 °F) even under normal
operating conditions. If the operator is allowed to approach the operating motor,
attach a warning label on a conspicuous position as shown in the gure. Failure to do
so may result in a skin burn(s). Warning label
