Field Connections—All Units
• Connect the control display panel cable to terminal block TB3 terminals 1 through 4 on the Lie-
bert XDC control board as shown (refer to Figure 18). The display panel must always be installed
in the conditioned space. The display panel may be mounted on the Liebert XDC’s front right door
if the Liebert XDC is located in the area that it conditions.
• Place the sensor in the higher-temperature portion of the cold aisle where the XD modules are
located. Alternatively, it may be placed on the return air side of the primary air mover (e.g., Lie-
bert Deluxe System/3 ™ ) in the room if it represents the conditions where all the XD cooling mod-
ules are located. Do not install the sensor where ambient air might cause false readings, for
example, near unsealed doors, windows and similar areas..
Field Connections—Optional for All Units
• Connect optional field wiring from remote devices to Remote Alarm Device, Common Alarm Out-
put, IGM and Remote Shutdown, if applicable. See terminal strip descriptions in Figure 18.
Field Connections—Air Cooled Units only
