4. Remove the Terminal Block Assembly (excluding TTS300/TGS230 compressors). Refer to "4.12.2
3-Phase Main Voltage Input Terminal Block Removal and Installation" on page 98.
5. Remove the DC Bus Bar and Capacitor Assembly. Refer to "4.22.3 DC Capacitor Bus Bar
Assembly Removal and Installation" on page 158.
6. Refer to "Figure 4-22 Backplane Connections" and remove the following connectors from the
Backplane:
• Pressure/temperature sensor connectors (J17, J18, and J19)
• IGV motor drive connector (J21)
Figure 4-22 Backplane Connections
7. Disconnect the cables from the suction and discharge pressure sensors. Refer to "Figure 4-23
Pressure/Temperature and SCR Temperature Sensor Locations - TTS300/TGS230", "Figure 4-25
Pressure/Temperature Sensors - TTH375/TGH285", and "Figure 4-25 Pressure/Temperature
Sensors - TTH375/TGH285" on page 70 for this and the following step.
