When mounting the motor on the flange, the motor must be aligned precisely in both the axial and radial
directions. All the fixing screws must be tightened to the tightening torque stipulated by the application,
taking care not to generate any warping.
Install the transmission devices
If the transmission device is installed incorrectly, this can damage the motor.
Transmission devices such as pulleys and gears must be mounted in compliance with the maximum axial
and radial loads defined in each motor's technical data sheet.
Follow the transmission device manufacturer's assembly instructions.
The motor and the transmission device must be aligned precisely both axially and radially. If this is not done,
it will result in abnormal operation, damage to the bearings and significant wear.
5.5.Electrical Installation
These motors are not designed to be connected directly to the line supply.
It is the installer's responsibility to define the electrical protection devices to be implemented according to the
regulations applicable to the end product range of application.
For the power supply to the power part we recommend using a double-insulated stabilized power supply.
The motor is not protected against polarity reversals on the power part.
The motor is regenerative, in other words it can feed back energy to the power supply during braking
phases. Voltage surges created in this way can reach levels that risk destroying the motor itself or devices
placed on the same power supply.
DANGER
ELECTRIC SHOCK
High voltages can appear unexpectedly on the motor connection.
• The motor produces a voltage when the shaft turns. Protect the
motor shaft from any external drive operation before working on the
drive system.
• The system manufacturer is responsible for complying with all
applicable regulations with regard to grounding the drive system.
Failure to comply with these precautions will result in death or
serious injury.

5.5.1. Connecting the Holding Brake (Optional)
WARNING
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE
Engaging the holding brake while the motor is running leads to rapid
wear and loss of braking force.
• Do not use the brake as a service brake.
• Note that "emergency stops" can also cause wear.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
WARNING
UNEXPECTED MOVEMENT
Releasing the holding brake can result in unexpected movement on
the installation.
• Make sure this cannot cause any damage.
• Do not continue with the test if there is anybody or any obstacle in
the danger zone.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
CAUTION
MALFUNCTION OF THE HOLDING BRAKE DUE TO INAPPROPRIATE
VOLTAGE
• If the voltage is too low, the holding brake cannot release, resulting in
wear.
• In the event of voltages higher than the specified value, the holding
brake will be subject to significant overheating.
Failure to comply with these precautions can result in injury or
damage to equipment.
A motor with a holding brake needs a corresponding control logic which releases the holding brake at the
start of the rotation movement, locking the motor shaft in time when the motor stops.
