    Each sensor requires a unique address in the CANbus loop connected to the cooling unit. We recommend that you set the DIP-switch sensor-number setting to correspond to the sensor’s location on the CANbus run. If settings are incorrect, the control will not operate properly. Vertiv™ | Liebert® iCOM™ Installer/User Guide...
  • Page 119 NOTE: Sensors are connected in a daisy chain via CANbus cabling to the cooling-unit control board. You can extend the sensor network (up to 10) by adding sensors to the end of the chain and adjusting the termination settings. Do not run individual wires from the sensors to the cooling unit.
