Dangerous voltages and currents exist on the drive when it is powered, and up to 60 seconds

after power is removed and the motor stops. When possible, disconnect the drive while

troubleshooting. High current can cause serious or fatal injury.

Perform the following steps before starting any procedure in this section:

1. Disconnect DC voltage input from the drive.

2. Check the drive closely for damaged components.

3. Check that no foreign conductive material has become lodged on the printed circuit board.

4. Verify that all connections are correct and in good condition.

5. Verify that there are no short circuits or grounded connections.

6. Check that the drive’s rated armature voltage and current is consistent with the motor ratings.

7. Verify that input voltage (battery) is within specied range.
