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.
AF TER DISCONNECTING INPUT POWER , W AIT FIVE (5) MINUTES FOR THE D ĆC
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 LOS
S OF LIFE .
Step 1. T
urn off , lock out, and tag the input power to the drive. W ait five minutes.
Step 2. V erify that the D ĆC bus voltage is zero. Refer to section 9.3.
Step 3. If a function loss coast Ćstop pushbutton has been installed, verify that it has been wired
correctly . Be sure the factory Ćinstalled jumper at terminals 16 and 20 (or 16A and 20A) has
been removed so that the coast Ćstop pushbutton will work.
WARNING
THE
USER MUST PRO VIDE AN EXTERNAL , HARD WIRED EMERGENCY STOP CIRCUIT OUTSIDE OF
THE DRIVE CIRCUITRY. THIS CIRCUIT MUST DISABLE THE SYSTEM IN CASE OF IMPROPER
OPERATION.
UNCONTROLLED MACHINE OPERA TION MA Y RESUL T IF THIS PROCEDURE IS NOT
FOLLOWED. F AILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN BODIL Y 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. V erify 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 user Ćsupplied 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 .
