Connecting The Motor Cables; Filter); Connection Diagram (Without Option +H366) - ABB ACS880-37 Hardware Manual

Connecting the motor cables (units without common
motor terminal cubicle or sine output filter)
On units without a common motor terminal cubicle or a sine output filter, the motor cables
connect to busbars located behind the inverter module(s). The location and dimensions of
the busbars are visible in the dimension drawings delivered with the drive, as well as the
example drawings presented in this manual (starting on page 227).
To allow the most room for the work, the modules can be removed completely from the
cabinet. For instructions, see
Especially in the case of multiple inverter modules in the same cubicle, you can consider
only removing the fan carriage of each module. This is faster than removing the entire
module, but allows less room for the connecting work. For instructions, see section
Removing and reinstalling the fan carriage of an inverter module
If the drive is equipped with a common motor terminal cubicle (option +H359) or a sine
output filter (option +E206), follow the procedure starting on page 120.
Note for frame 1×R8i + 1×R8i: It is practical to remove all three modules (LCL filter,
supply, inverter) before making the motor and input power cable connections.


All parallel-connected inverter modules are to be cabled separately to the motor. 360°
earthing is to be used at cable lead-throughs.
