Product Description

Field Connections—All Units

•Connect the control display panel cable to terminal block TB3 terminals 1 through 4 on the Lie- bert XDP control board as shown (refer to Figure 15). The display panel may be mounted on the Liebert XDP’s front right door if the Liebert XDP is located in the area that it conditions. The dis- play panel must always be installed in the conditioned space.

•Connect the provided remote temperature / humidity sensor extension cable to the factory-installed cable connected to P16 on the control board. Install the sensor in the higher- temperature portion of the cold aisle where the XD modules are located. Alternatively, it can be placed on the return air side of the primary air mover (e.g., Liebert Deluxe System/3™) in the room if it represents the conditions where all the XD cooling modules are located. Do not install the sensor where ambient air may cause false readings, for example, near unsealed doors, windows and similar areas.

Field Connections—Optional for All Units

•Connect field wiring from the optional Liebert XD cooling module condensation detection circuit to terminal strip locations H2O (24) and XDOC (51).

•Connect optional field wiring from remote devices to remote alarm device, common alarm output, site monitor and remote shutdown, if applicable. See terminal strip descriptions in Figure 15.
