Precautions for Connected Machinery

WARNING! Sudden Movement Hazard. Clear all personnel from the drive, motor, and machine area before applying power. System may

start unexpectedly upon application of power, causing death or serious injury.

WARNING! Sudden Movement Hazard. Always check the operation of any fast stop circuits after they are wired. Fast stop circuits are

required to provide safe and quick shutdown of the drive. Prepare to initiate an emergency stop during the test run. Operating a drive with

untested emergency circuits could result in death or serious injury.

• The motor should come to a complete stop without problems.
• Connect the load and machinery to the motor.
• Fasten all installation screws properly and check that the motor and connected machinery are held in place.
