1.3. Basic Information
DANGER
DANGEROUS PHENOMENON LINKED TO ELECTRIC SHOCK, EXPLOSION OR
EXPLOSION DUE TO AN ELECTRIC ARC
• Only qualified personnel who are familiar with and fully understand the contents of
this manual are authorized to work on this product. Only qualified personnel are
authorized to undertake installation, setting, repair and maintenance.
• The installation manufacturer is responsible for complying with all the applicable
requirements and regulations with regard to grounding the drive system.
• It is the user's responsibility to define whether it is necessary to ground the motor,
depending on its intended use.
• Do not touch unprotected live parts.
• Only use electrically-isolated tools.
• AC voltages can be connected to unused conductors in the motor cable. Isolate
unused conductors at both ends of the motor cable.
• The motor produces a voltage when the shaft turns. Protect the motor shaft from
any external drive operation before working on the drive system:
– De-energize all connections.
– Attach a notice saying "DO NOT START UP" on all the switches.
– Protect all the switches from switching on.
– Wait for the internal motor capacitors to discharge. Measure the voltage on the
power cable and check that it is less than 12 VDC.
• Install protective covers and ensure they are closed before energization.
Failure to comply with these precautions will result in death or serious injury.
WARNING
LOSS OF COMMAND CONTROL
• When perfecting the command concept, the installation manufacturer must take
account of the possibilities for potential failure of command paths and provide, for
certain critical functions, the means of returning to safe states during and after the
failure of a command path.
Examples of critical command functions are:
EMERGENCY STOP, end position limiting, network outage and restarting.
• Separate or redundant command paths must be available for critical functions.
• Comply with the accident prevention instructions and all current safety directives.
• Any installation in which the product described in this manual has a central role
must be carefully and meticulously checked prior to commissioning to ensure it is
working properly.
Failure to comply with these precautions can result in death or serious injury.
WARNING
UNBRAKED MOVEMENT
In the event of a power outage and errors resulting in disconnection of the power
stage, the motor is no longer braked in a controlled way and can cause damage.
• Prevent access to the hazardous zone.
• If necessary, use a damped mechanical stop or a service brake.
Failure to comply with these precautions can result in death, serious injury or
damage to equipment.
