3.3 Customer unit overview
Customer units are optional modules, which offer a variety of
control inputs and outputs in addition to the standard scope. The
options for controlling the frequency inverter can be modified
according to requirements.
A customer unit can be integrated in each frequency inverter.
After the mains voltage is connected and switched on, it is
automatically recognised by the inverter and the additional
functions are made available. The cable connection is
established using screw connectors. This makes the connection
of devices very easy and convenient.
