4.12.2.3 3-Phase Main Voltage Input Terminal Block Removal - TTS/TGS/TTH/TGH Rev. F and Earlier (Except TTS300/
TGS230)
1. Disconnect the three (3) connectors of the Soft Start AC/DC harness from the bus bars.
2. Remove the three (3) fasteners that secure the AC Bus Bars to the SCRs. For Revision F and
earlier compressors, refer to "Figure 4-85 Input Terminal Block Removal - TTS/TGS/TTH/TGH
Rev. F and Earlier (Except TTS300/TGS230)" and for Revision H compressors, refer to "Figure
4-86 Input Terminal Block Removal - TTS/TGS/TTH/TGH Rev. H (Except TTS300/TGS230)" on
page 100 for this and the following three (3) steps.
3. Remove the six (6) fasteners that secure the three (3) AC Bus Bars to the Terminal Block.
4. Remove the AC Bus Bars.
NOTE
If the terminal block is being removed to access other components, it is not necessary to remove the AC Bus Bars from the
terminal block on Rev F and earlier compressors - the terminal block and bus bars can be removed as an assembly. On Rev H
compressors, the center AC Bus Bar must be removed to access a mounting fastener for the terminal block but the two (2) bus
bars can remain attached.
5. Remove the fasteners that secure the Terminal Block to the casting and remove the Terminal
Block.
a. Rev F and ealier compressors use two (2) M5x45 fasteners that attach the Terminal Block to
the compressor housing.
b. Rev H compressors use three fasteners; it uses the same two (2) as listed above and there
is an additional M6x16 fastener that is located at the back center of the Terminal Block
(under the center AC Bus Bar). This fastener secures the Terminal Block to the SCR Cooling
Plate.
6. Remove the two (2) spacers if the Terminal Block is to be replaced with a new one.
7. Continue to Section "4.12.2.5 3-Phase Main Input Terminal Block Installation - TTH/TGH/TTH/
TGH (Except TTS300/TGS230)" on page 101.
