Motor cabling

The motor cabling connects to the module via a quick connector at the back of the
module. By default, each inverter module is cabled individually to the motor. With an
optional common motor terminal cubicle, the outputs of the parallel-connected inverter
modules are connected to a separate cubicle containing a single set of output busbars.
