Figure 4-90 Input Terminal Block Installation - TTS/TGS/TTH/TGH Rev. H (Except TTS300/TGS230)
1. Install the two (2) spacers if previously removed.
2. Place the Terminal Block on the compressor housing.
a. For Rev F and ealier compressors, use two (2) M5x45 fasteners to attach the Terminal Block
to the compressor housing and and torque to 4 Nm (35 in.lb.).
b. For Rev H compressors, loosely install the three (3) fasteners. Then torque the two (2)
M5x45 fasteners to 4 Nm (35 in.lb.) and torque the rear M6x16 fastener to 5 Nm (44
in.lb).
3. Place the three (3) AC Bus Bars onto the Terminal Block and and finger tighten all fasteners.
secure them with the six (6) Terminal Block fasteners. Torque the fasteners to 4 Nm (35 in.lb.).
a. For Rev F and ealier compressors, torque the six (6) fasteners to 3 Nm (27 in.lb.) and the
three (3) M8x20 AC Bus Bar Fastners to 9 Nm (80 in.lb.).
b. For Rev H compressors, torque the six (6) M5x12 fastners to 2Nm (17 in.lb.) and the three
(3) M6x16 AC Bus Bars to SCR fasteners to 5 Nm (44 in.lb.).
4. Reconnect the three (3) terminals of the Soft Start cable harness to the AC Bus Bars.
5. Install the mains input cables to the Terminal Block and torque to 21 Nm (15 ft.lb.).
6. Continue to Section "4.12.2.6 General 3-Phase Main Voltage Input Terminal Block Installation".
