4. Install the SCR Cooling Manifold to the Inverter Cooling Manifold. Refer to Section 4.19.4 SCR Cooling
Manifold Specific Installation Steps - TTS300/TGS230 on page 160.
5. Remove the backing material from the cooling manifold of the new Inverter.
6. Install all 20 M6x30 fasteners into the Inverter assembly. This will aid in the alignment when lowering it
onto the compressor housing.
NOTE
It is recommended that the new fasteners supplied with the kit be used to ensure proper torque is obtained.
7. Carefully install the Inverter on the compressor housing with the SCR temperature sensor cable (if
equipped) run on top where the SCR cooling manifold meets the Inverter Cooling Manifold.
8. Torque the M6x30 Inverter fasteners in a diagonal pattern to 3 Nm (27 in.lb.) on the first pass then to
8.5 Nm (75 in.lb.) on the second pass. Refer to Figure 4-208 Inverter Fastener Locations -
TTS300/TGS230.
