8.0 COMPLETING THE INSTALLATION
This chapter provides instructions on how to perform a final check of the installation before power is
applied to the drive.
DANGER
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.
8.1 Checking the Installation
Use the following procedure to verify the condition of the installation:
DANGER
DĆC BUS CAPACITORS RETAIN HAZARDOUS VOLTAGES AFTER INPUT POWER HAS BEEN
DISCONNECTED. AFTER DISCONNECTING INPUT POWER, WAIT FIVE (5) MINUTES FOR THE DĆC
BUS CAPACITORS TO DISCHARGE AND THEN CHECK THE VOLTAGE WITH A VOLTMETER TO
ENSURE THE DĆC BUS CAPACITORS ARE DISCHARGED BEFORE TOUCHING ANY INTERNAL
COMPONENTS. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN SEVERE BODILY
INJURY OR LOSS OF LIFE.
Step 1. Turn off, lock out, and tag the input power to the drive. Wait five minutes.
Step 2. Verify that the DĆC bus voltage is zero. Refer to section 9.3.
Step 3. If a function loss coastĆstop pushbutton has been installed, verify that it has been wired
correctly. Be sure the factoryĆinstalled jumper at terminals 16 and 20 (or 16A and 20A) has
been removed so that the coastĆstop pushbutton will work.
WARNING
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.
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 specification and that the wires are tightened
properly.
Step 8. Check that userĆsupplied branch circuit protection is installed and correctly rated.
Step 9. Check that the incoming power is rated correctly.
Step 10. Check the motor installation and length of motor leads.
Step 11. Disconnect any power correction capacitors connected between the drive and the motor.
Step 12. Check that the rating of the transformer (if used) matches the drive requirements and is
connected properly.
