2.2.2 Connect the cascading cables between the
appliances
To install the intelligent cascading cables:
▶ Connect all appliances together to form a ring.
– Connect units in a row from the first to the last unit and
then connect the last unit to the first one to close the
ring (fig. 9 and fig. 10).
– If one cable is not long enough, connect two or more
cables in a row.
– Use the holes at the bottom of the appliance to guide
the cables to/from the appliance interior.
▶ Proceed with the same steps in section 2.2.1, in reverse
order to connect HMI and install front cover in the
appliance.
Appliances are now ready for cascading activation and
configuration.
