Inverter Assembly Component Replacement Procedures Chapter 3
Install Components
1. Mount brackets to the new Current Transducer. Torque screw to 5.6 N•m
(50 lb•in).
2. Slide Output Busbar through the Current Transducer assembly with the
angled end to the left.
3. Replace the Current Transducer assembly in mounting position by
reversing the process used in Step 6.
of the removal process.
4. Secure the Current Transducer assembly to the heatsink with two torx
screws. Torque to 2.9 N•m (26 lb•in).
5. Reinstall the AC Output Busbar:
a. Place the AC Output Busbar onto the two existing standoff set screws.
b. Reinstall the six torx screws that secure the busbar to the IGBT
heatsink. Torque to 5.6 N•m (50 lb•in).
c. Reinstall the two standoff nuts. Torque to 5.6 N•m (50 lb•in).
6. Reinstall the Output Busbar:
a. Reinstall the set screw. Hand tighten.
b. Reinstall the torx bolt that secures the Output Busbar to the AC
Output Busbar. Torque to 9.0 N•m (80 lb•in).
c. Reinstall the two hex head bolts that secure the Output Busbar to the
U, V, or W Busbar. Torque to 5.6 N•m (50 lb•in).
d. Reinstall the standoff nut to the set screw. Torque the nut to 5.6 N•m
(50 lb•in), which will torque the set screw correctly.
7. Reconnect the wire to the Current Transducer.
8. Replace all safety shields and enclosure covers before applying power to the
drive.
