the number of new analogue outputs to be connected. No free slots for additional MAO modules
are available in the existing racks.
In this case, additional MAO modules are required, in correspondence with number of new ana-
logue outputs to be connected.
Additional MAT/MAT TS/MUT modules are also required.
One or more new racks and the necessary CAN bus connecting cables will also be needed.
Always turn off the voltage when connecting a new rack. After turning off the voltage supply,
mount and install the additional rack. The connection of the racks and the necessary configuration
changes [MIB module] are described in the Installation and Start-Up Guide. Take special care to
choose the correct CAN bus baudrate and CAN node number.
NOTE: Whenever you connect additional sensors, always make sure that the voltage supply to
the system is still adequate [
