n 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.

Step Display/Result
1.
Remove any power source lockouts on the P1000 Bypass then turn the main input disconnect
handle clockwise to energize the P1000 Bypass. Refer to Input Circuit Breaker on page
32 for details.
Use a multimeter to check all three-phase voltages for proper levels and balance and record
these levels for future reference.
During this sequence, the control logic will briefly (< 3 s) perform a self-test to ensure proper
operation.
