2. Verify that the branch circuit protection and AC input
wiring 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 protection
are properly secured. Inspect the ground cable and ensure
it is properly connected at the branch and to the ground
lug in the VFD.
6. Verify the conduit for the power wiring in securely con-
nected to the VFD flanged cover and runs continuously to
the branch protection.
7. Verify that the incoming and outgoing wires have been
properly connected inside of the line reactor enclosure if a
separate line reactor has been added to the chiller.
8. Ensure the control and signal wires connected to the
chiller controller or the VFD are in separate conduit.
VFD Cooling System Leak Inspection
1. 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 and
the TXV valve.
Power Up Verification
1. Inspect control wiring inside the VFD and verify the in-
tegrity of the connections between the integrated starter
module (ISM) and the VFD module.
2. Close the control power switch in the VFD enclosure.
3. Close the oil pump power switch inside the VFD
enclosure.
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 outs
and close all disconnects.
7. Verify that the ICVC display powers up and goes to the
default 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 attempts
to reset a fault, the fault code will be shown and the VFD will
be disabled.
ICVC Parameters for VFD — The chiller controller must have
its job specific parameters set as defined by the job sheet or
installed nameplates. Below are the job specific parameters
that must be set:
