4.11.2 3-Phase Main Voltage Input Terminal Block Removal and Installation
4.11.2.1 General 3-Phase Main Voltage Input Terminal Block Removal
1. Isolate compressor power as described in Section 1.8 Electrical Isolation on page 22.
2. Disconnect the mains input cables from the Terminal Block.
3. For TT300/TG230 compressors, continue to Section 4.11.2.2 Specific 3-Phase Main Voltage Input
Terminal Block Removal - TTS300/TGS230; for all others, continue to Section 4.11.2.3 3-Phase Main
Voltage Input Terminal Block Removal - TTS/TGS/TTH/TGH (Except TTS300/TGS230) on page 103.
4.11.2.2 Specific 3-Phase Main Voltage Input Terminal Block Removal - TTS300/TGS230
1. Remove the three (3) M6x16 fasteners that connect the Fast Acting Fuses and Soft Start AC Ring
terminals L1, L2, L3, to the SCRs. Refer to Figure 4-81 Terminal Block Removal - TTS300/TGS230 for this
and the following four (4) steps.
2. Remove the six (6) Fuse to Terminal Block fasteners that secure the fuses to the Terminal Block Adapter.
3. Remove the fuses.
4. Remove the insulating Mylar.
5. Remove the Terminal Block fasteners that secure the Terminal Block to the compressor housing and
remove the Terminal Block.
