6. Remove the motor temperature sensor leads (Fig. 23), the
motor ground lead, and the bolts that secure the VFD
enclosure to the terminal box transition piece.
7. Disconnect the communication cables from the back of
ICVC (International Chiller Visual Controller) (Fig. 24).
8. Disconnect the high pressure switch leads. Consult the
wiring diagrams in the section Make Electrical Connec-
tions (page 51) for terminal block and terminals (they are
dependent on the drive type).
9. Unplug connectors CN1A, CN1B, CN2, and CN3
10. Disconnect the control panel ground wire located next to
connectors CN1A and CN1B (see Fig. 25 for all com-
pressors).
11. Disconnect the VFD cooling lines (Fig. 27) and cover all
openings (does not apply to units with P compressors).
12. Remove the 12 screws that secure the control panel to the
VFD enclosure. Tilt the control panel away from the back
of the control center.
13. Position the control panel on a safe surface and secure it
in place to prevent damage.
