Designing a Liebert XD Solution

3.25 Electrical

Make all wiring and electrical connections in accordance with local and national codes. Refer to the

applicable table in 9.0 - Specifications and Model Number Nomenclature regarding wire size

and circuit protection requirements. Refer to electrical schematic when making connections.

3.26 Temperature/Humidity Sensor Locations

The display panel sensor and Liebert iCOM sensor (shipped loose) must always be installed in the

conditioned space. The display panel sensor and Liebert iCOM sensor may be mounted on the Liebert

XDC/XDP’s front door if the unit is located in the area that it conditions.

The remote temperature / humidity sensor for the Liebert XDP and the Liebert XDC should be

installed in the higher-temperature portion of the cold aisle where the Liebert XD modules are

located. Alternatively, it can be placed on the return air side of the primary air mover, such as a

Liebert DS, in the room if it represents the conditions where all the Liebert XD cooling modules are

located. It should not be installed where ambient air might cause false readings, for example, near

unsealed doors, windows and similar areas.
