Installation position
The motor can be installed in any position.
Installation
When fitting the motor on the flange, it must be aligned precisely, both axially and radially. All securing
screws must be tightened to the torque prescribed by the application, taking care not to cause any warping.
Fitting transmission devices
Fitting transmission devices incorrectly could damage the motor.
Transmission devices such as pulleys and gears must be fitted with reference to the maximum axial and
radial forces specified in the data sheet for each motor.
Follow the manufacturer's fitting instructions for each transmission device.
The motor and transmission device must be aligned accurately, both radially and axially. Any failure to do so
will result in erratic operation, damage to bearings and a high level of wear.
4.5. Electrical installation
These motors are not designed to be connected directly to the electrical system.
It is the installer's responsibility to specify the electrical protection to be deployed with regard to the
regulations applicable to the field of use of the final product.
For the supply to the power part, we recommend the use of a stabilised double-insulated power supply unit.
The motor's power stage is not protected against reversed polarity.
The motor is said to be regenerative, i.e. it can feed back energy to the power supply during braking phases.
Voltage surges created in this way can reach levels that risk damaging the motor itself or to devices
connected to the same power supply.
DANGER
ELECTRIC SHOCK
High voltages can occur unexpectedly at the motor connection.
• The motor produces a voltage when the shaft rotates. Isolate the
motor shaft from any external driving force before doing any work on
the drive system.
• The system's manufacturer is responsible for complying with all the
rules applicable to the earthing of the drive system.
Failure to take these precautions could result in death or serious
injury.
WARNING
UNEXPECTED MOVEMENT
Drives may move unexpectedly, due to an incorrect connection or
some other error.
• Only start the installation if there is no person or obstacle inside the
danger zone.
• Make initial test movements with no load connected.
• Do not touch the motor shaft or connected drive components.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
