    4) Disconnect and remove the old reactive power controller. 5) Plug the CX plus into the switch panel section and fix it with the two mounting brackets. (Section 138 x 138 mm) 6) Connect the protective conductor to the PE terminal of the metal back of the CX plus.
  • Page 6 11) Activation of user-guided initial commissioning “FIrSt SEtUP“ after confirming “YES“. Afterwards all required parameters are requested by CX plus. The choice of “NO” requires, that the user implements the following parameters (12) … 15)) manually. 12) The current transformer factor (Ct) must be entered.
  • Page 7 Questions during commissioning: 1) No AUTO display → control stopped Reasons: Manual operation, control is switched off, temperature is too high, current is less than 15 mA, voltage or THD of voltage are not permitted 2) U ALARM display → voltage out of tolerance Check settings for rated voltage (SETUP/ Un) and voltage transformer (SETUP/ Pt) 3) I Lo ALARM display →...

  • Page 14 In case of incorrect connection of the voltage or current path (phase, polarity), the reactive power controller cannot be operated. Thus, the connection should be corrected. Since this is not always possible, the CX plus alternatively provides the following functions: Automatic initialisation: SETUP/ 100/ AI The AI switches all outputs on and off several times.
