Completing the Installation
This chapter provides instructions on how to perform a final check of the installation
before power is applied to the drive.
7.1 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.
Step 3. If a function loss coast-to-stop pushbutton has been installed, verify that it
has been wired correctly.
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 nothing is 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 terminals
are tightened properly.
Step 9. Check that user-supplied branch circuit protection is installed and correctly
rated.
Step 10. Check that the incoming power is rated correctly.
Step 11. Check the motor installation and the length of motor leads.

ATTENTION: Only qualified electrical personnel familiar with the
construction and operation of this equipment and the hazards involved
should start and adjust it. Read and understand this manual in its entirety
before proceeding. Failure to observe this precaution could result in
severe bodily injury or loss of life.
!
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power, wait five
(5) minutes for the DC bus capacitors to discharge and then check the
voltage with a voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of life.
ATTENTION: The drive start/stop/enable control circuitry includes solid
state components. If hazards due to accidental contact with moving
machinery or unintentional flow of liquid, gas or solids exist, an additional
hardwired stop circuit may be required to remove the AC line to the drive.
An auxiliary braking method may be required.
