3. Bend the cable harness under the Mains Terminal Block and route it toward the capacitor side
of the compressor.
4. Install the harness onto the IGV Feedthrough.
5. Rotate the clamp over the IGV connector and torque the M5x16 fastener to 25 Nm (18 ft.lb.)
Refer to "Figure 4-26 IGV Connector Clamp".
6. Connect the SCR Manifold Sensor connector (excluding TTH compressors). Refer to "Figure
4-23 Pressure/Temperature and SCR Temperature Sensor Locations - TTS300/TGS230" on
page 69 and "Figure 4-25 Pressure/Temperature Sensors - TTH375/TGH285" for this and the
following step.
7. Connect the cables to the suction and discharge pressure sensors.
8. Insert the molded rubber grommet in the notch in the main compressor housing.
9. Install the four (4) Backplane connectors (J17, J18, J19, and J21).
• Soft Start interface connector (J22)
• Pressure/temperature sensor connectors (J17, J18, and J19)
• IGV motor drive connector (J21)
10. Install the DC Capacitor Bus Bar Assembly. Refer to "4.22 DC Capacitor Bus Bar Assembly" on
page 156.
