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 in the inverter module cubicles. To access the terminals, the
cooling fans and other equipment in front of the terminals must be removed from the cubicle.
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 in chapter
Dimensions
.
If the drive is equipped with a common motor terminal cubicle (H359) or a sine
output filter (E206), follow the instructions in section
(units with common motor terminal cubicle or sine output filter) (page 40)
.
