3. Remove the Snubber Capacitors. Refer to Figure 4-185 Snubber Capacitor Removal - TTS/TGS/TTH/TGH
(Except TTS300/TGS230) on page 171.
4. Using a multimeter set for capacitance measurement, place the leads on the capacitor terminals. The
measured value should be 0.42μF to 0.52μF.
4.21.3 DC Capacitor Bus Bar Assembly Removal and Installation
• • • CAUTION • • •
The DC Bus Capacitor Assembly should not be disassembled. Bleed resistors (or Balanced Board), bus bars, and capacitors are factory
assembled and should only be removed and installed as a single component. Incorrect disassembly/assembly will result in damage to the
compressor.
4.21.4 DC Capacitor Bus Bar Assembly General Removal
1. Isolate the compressor power as described in Section1.8 Electrical Isolation on page 22 of this manual.
2. Remove the Soft Start. Refer to Section 4.14.3 Soft Start Removal and Installation on page 117.
3. Continue to Section 4.21.4.1 DC Capacitor Bus Bar Assembly Removal - TTS300/TGS230 for
TTS300/TGS230 compressors and for all other TT/TG compressors, continue to Section 4.21.4.2 DC
Capacitor Bus Bar Assembly Removal - TTS/TGS/TTH/TGH (Except TTS300/TGS230) on page 170.
4.21.4.1 DC Capacitor Bus Bar Assembly Removal - TTS300/TGS230
1. Remove the DC Bus Bars from the SCRs. Refer to Figure 4-179 DC Bus Bar and Soft Start Harness
Removal - TTS300/TGS230 for this and the following step.
2. Disconnect the DC+ and DC- of the Soft Start harness from the DC bus assembly noting the orientation.
Figure 4-179 DC Bus Bar and Soft Start Harness Removal - TTS300/TGS230
3. Disconnect the snubber capacitors from the Inverter noting the leg orientation of one leg is longer
than the other. Refer to Figure 4-180 Snubber Capacitor Removal - TTS300/TGS230 on page 169.
