Completing the Installation

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

been wired correctly. Be sure the factory-installed jumper at terminals 16 and
20 has been removed so that the coast-stop pushbutton will work.

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 the wiring to the terminal strip and the power terminals is correct.

Step 7. Check that the wire size is within terminal specifications and that the wires

are tightened properly.

Step 8. Check that user-supplied branch circuit protection is installed and correctly

rated.

Step 9. Check that the incoming power is rated correctly.

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 user must provide an external, hardwired emergency
stop circuit outside of the drive circuitry. This circuit must disable the
system in case of improper operation. Uncontrolled machine operation
may result if this procedure is not followed. Failure to observe this
precaution could result in bodily injury.
