    12 LIEBERT ICOM HARDWARE INSTALLATION Your unit includes the Liebert iCOM controller. This section describes the installation of connections and cabling to fully utilize the iCOM features. 12.1 Installing Wired Remote Sensors Up to 10 remote-sensor modules, installed in the monitored racks and connected to the cooling unit, provide control and reference input to iCOM and building-management systems.
  • Page 111 If settings are incorrect, the control will not operate properly. The DIP switches in 2T sensors included with each Liebert iCOM are factory-set according to Table 11.3 below. If adding additional 2T sensors, use the steps that follow to set the DIP switches.
  • Page 112 The last 2T sensor in the array must be terminated. If more than the 3 factory-supplied sensors are installed, sensor #3 must be unterminated and the last sensor must be terminated. NOTE: Up is on, down is off on the DIP switch. Figure 11.7 DIP switches in 2T sensor Vertiv | Liebert® iCOM™ Installer/User Guide |...
