5. SWITCHING ON
5.1. Preparations for switching on
Before switching on:
Check that the mechanical installation is correct.
Check that the electrical installation has been done professionally: in particular, check the connections
on protective conductors and earth connections. Ensure that all connections are correct and sound and
that screws are properly tight.
Check the ambient conditions and conditions for use: ensure that the prescribed ambient conditions are
met and that the drive solution complies with the intended conditions for use.
Check that any transmission devices already fitted are balanced and accurately aligned.
Check that the conditions of use do not cause any abnormal over-voltages for the product or the
application.
Check that the holding brake can support the maximum load. Check that after the braking voltage is
applied, the holding brake releases correctly. Ensure that the holding brake is properly released prior to
movement starting.
Check that the connector protection plug is in place.
WARNING
UNEXPECTED MOVEMENT
Drives may move unexpectedly, due to an incorrect connection or
some other error.
• Check the wiring.
• Only start the installation if there is no person or obstacle inside the
danger zone.
• Make initial test movements with no load coupled.
• Do not touch the motor shaft or associated drive components.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
WARNING
ROTATING PARTS
Rotating parts can cause injury or catch clothing or hair. Loose parts or
unbalanced parts can be thrown off.
• Check that all rotating parts are secure.
• Fit a guard over rotating parts.
If these precautions are not taken, the result could be death,
serious injury or damage to equipment.
