Returning The Module - ABB ACS880-37 Hardware Manual

Returning the module

1. Remove the air baffle and install the module in reverse order. Use the following
tightening torques:
•
DC busbar assembly to upper insulators (2 × M8): 9 N·m (6.6 lbf·ft)
•
DC busbar assembly to lower insulators (2 × M10): 18 N·m (13.3 lbf·ft)
•
Fuses to DC busbars: 50 N·m (37 lbf·ft) (Bussmann), 46 N·m (34 lbf·ft)
(Mersen/Ferraz-Shawmut)
•
Module to cabinet frame (4 × M8): 22 N·m (16 lbf·ft)
•
DC busbar assembly to module DC input (2 × M12): 70 N·m (52 lbf·ft)
2. Restore the original wiring (STO and control unit power supply whenever needed).
3. Set parameter 195.13/95.13 to 0 to disable the reduced run function.
4. If the module reinstalled was an inverter module and the Safe torque off function is in
use, perform an acceptance test as described under
test (page 243).
