11. Continue to "4.22.5 DC Capacitor Bus Bar Assembly General Installation Steps" on page 163.
1. Position the DC Bus Bar and Capacitor Assembly into place. Refer to "Figure 4-185 Capacitor
Assembly Removal - TTS300/TGS230" on page 160.
2. Loosely install the Snubber Capacitors to the Inverter noting the leg orientation. Refer to
"Figure 4-183 Snubber Capacitor Removal - TTS300/TGS230" on page 159.
3. Loosely install the DC Bus Bars to the SCRs. Refer to "Figure 4-182 DC Bus Bar and Soft Start
Harness Removal - TTS300/TGS230" on page 159 for this and the following step.
4. Loosely install DC Bus Bars to the DC Bus Assembly.
5. Starting from the Capacitor side, torque the M6x16 Snubber Capacitor fasteners to 7 Nm (62
in.lb.).
6. Connect the DC+ and DC- of the Soft Start harness to the DC bus assembly noting the
orientation and torque to 10 Nm (7 ft.lb.). Refer to "Figure 4-182 DC Bus Bar and Soft Start
Harness Removal - TTS300/TGS230" on page 159.
7. Torque the two (2) DC Bus Bars to SCR fasteners to 5 Nm (44 in.lb.).
8. Torque the two (2) Capacitor DC Bus Bar to SCR Bus Bar fasteners to 10 Nm (7 ft.lb.).
9. Place the capacitor membrane, foam-side up, underneath the main compressor housing and
then Install the nylon nuts to the base of the DC Capacitor Bus Bar Assembly, and torque to 7
Nm (62 in.lb.). Refer to "Figure 4-184 Capacitor Nut Removal - TTS300/TGS230" on page 159.
10. Connect the SCR Gate cable harness to the SCRs noting its orientation. Refer to "Figure 4-143
SCR Connections - TTS300/TGS230" on page 134.
11. Continue to "4.22.5 DC Capacitor Bus Bar Assembly General Installation Steps".
1. Position the DC Bus Bar and Capacitor Assembly into place.
2. Loosely Install the six (6) DC bus M8x20 fasteners to the SCRs.
3. Loosely install the Snubber Capacitors to the Inverter noting the leg orientation.
4. Starting from the Capacitor side, torque the Snubber Capacitors to 7 Nm (62 in.lb.).
5. Torque the six (6) M6x16 SCR Bus Bar fasteners to 5 Nm (44 in.lb.).
6. Place the capacitor membrane foam-side up, underneath the main compressor housing and
Install the nylon nuts to the base of the DC Capacitor Bus Bar Assembly, torque to 7 Nm (62
in.lb.).
7. Install the SCR Gate Cables onto the SCRs. Refer to "Figure 4-159 SCR Gate Cable and AC/DC
Harness Connections - TTS/TGS/TTH/TGH Rev. F and Earlier (Except TTS300/TGS230)" on page
143.
8. Continue to "4.22.5 DC Capacitor Bus Bar Assembly General Installation Steps".
1. Install the Soft Start. Refer to "4.15.6 Soft Start Installation (Closed-Top)" on page 116.
2. Install the top covers. Refer to "4.2 Compressor Covers" on page 56.
3. Return the compressor to normal operation.
