12.10 Rules for wiring with DRIVE-CLiQ
Rules for FW2.4
● The Voltage Sensing Module may be connected directly to a DRIVE-CLiQ port of the
● If possible, the CUA31 should be connected at the end of the line.

1) If a CUA31 is connected as the first module to the Control Unit, then the maximum number is
decreased by one.
