3.5. 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.
WARNING
UNEXPECTED MOVEMENT
As a result of incorrect wiring or other error, the drives can execute
unexpected movements.
• Do not start up the installation if there is anybody or any obstacle
in the danger zone.
• Execute the initial test movements without loads connected.
• Do not touch the motor shaft or related drive elements.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
