WARNING
VOLTAGE SURGES
During braking phases, the motor generates voltage surges.
• Check that these voltage surges are acceptable to other devices
connected on the same power supply.
• If possible, use an external circuit to limit voltage surges.
if the brake is used intensively.
Failure to comply with these precautions can result in death,
serious injury or damage to equipment.
CAUTION
FIRE CAUSED BY BAD CONTACTS
If the connector is not properly inserted the motor connector can
overheat, causing the contacts to melt due to an electric arc.
• Incorrect connection can cause overheating due to an electric arc.
Failure to comply with these precautions can result in injury or
damage to equipment.
CAUTION
IRREPARABLE PRODUCT DAMAGE CAUSED BY REVERSED POLARITY
Incorrect connection of the power can result in reversed polarity,
resulting in destruction of the circuit board inside the motor.
• Check the conformity of the power connections.
• Place a slow-blow fuse on the power supply that is appropriately
sized for the current the motor needs to absorb in the application.
Failure to comply with these precautions can result in injury or
damage to equipment.
Connecting the protection conductor
It is the installer's responsibility to define whether the motor needs to be grounded.
The mounting flange should be used for this purpose.
Never connect or disconnect the product power supply leads while the voltage is applied.
