Up to 7 extension base units can be added.
Limit the total length of the extension cable to 13.2m or less.
When using extension cables, keep them away from the main circuit cables (high voltage,
large current).
Assign the extension stage numbers in ascending order. Do not assign two or more modules
to one stage.
Connect the extension cable from OUT of the extension cable connector of the base unit to in
of the connector of the next extension base unit.
The QA1S51B can be connected to the last extension stage only because it does not have
an extension cable connector (OUT).
