Connecting the motor cables (units without common motor
terminal cubicle)
On units without a common motor terminal cubicle, 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), follow the
instructions in section
Connecting the motor cables (units with common motor terminal
cubicle) (page 92) .
