This chapter provides instructions on how to perform a final check of the installation
before power is applied to the drive.
8.1 Checking the Installation
Use the following procedure to verify the condition of the installation:
Step 1. Turn off, lock out, and tag the input power to the drive. Wait five minutes.
Step 2. Verify that the DC bus voltage is zero. Refer to section 9.3.
Step 3. If a function loss coast-stop pushbutton has been installed, verify that it has
Step 4. Remove any debris, such as metal shavings, from around the drive.
Step 5. Check that there is adequate clearance around the drive.
Step 6. Verify that there is nothing mounted behind the drive.
Step 7. Verify that the wiring to the terminal strip and the power terminals is correct.
Step 8. Check that the wire size is within terminal specification and that the wires are
Step 9. Check that user-supplied branch circuit protection is installed and correctly
