77DRIVE PROTECTION AND OTHER INCOMINGWIRING1. Verify that the branch disconnects or other local discon-nects are open and properly tagged out.2. Verify that the branch circuit protection and AC inputwiring to the VFD are in accordance with NEC/CEC(National Electrical Code/California Energy Commis-sion) and all other local codes.3. Verify that the fuses are per the field wiring diagram.4. Verify that the incoming source does not exceed 85 kA.5. Verify the power lugs in the VFD and branch protectionare properly secured. Inspect the ground cable and ensureit is properly connected at the branch and to the groundlug in the VFD.6. Verify the conduit for the power wiring in securely con-nected to the VFD flanged cover and runs continuously tothe branch protection.7. Verify that the incoming and outgoing wires have beenproperly connected inside of the line reactor enclosure if aseparate line reactor has been added to the chiller.8. Ensure the control and signal wires connected to thechiller controller or the VFD are in separate conduit.VFD Cooling System Leak Inspection1. Check for leaks on the refrigerant cooling flange connec-tions to the VFD enclosure.2. Check for leaks on all tubing internal to the VFD enclo-sure, the tubing flair connection to the VFD module andthe TXV valve.Power Up Verification1. Inspect control wiring inside the VFD and verify the in-tegrity of the connections between the integrated startermodule (ISM) and the VFD module.2. Close the control power switch in the VFD enclosure.3. Close the oil pump power switch inside the VFDenclosure.4. Verify the VFD disconnect switch is in the open position.5. Close and latch the doors of the VFD enclosure.6. Apply power to the VFD enclosure. Remove lock outsand close all disconnects.7. Verify that the ICVC display powers up and goes to thedefault screen.8. Close the VFD disconnect switch.The VFD is configured to attempt an automatic reset of mi-nor faults every 30 seconds. After a total of 10 failed attemptsto reset a fault, the fault code will be shown and the VFD willbe disabled.ICVC Parameters for VFD — The chiller controller must haveits job specific parameters set as defined by the job sheet orinstalled nameplates.
