6.2Connecting Low Voltage Wiring—Optional

Low voltage connections to the Liebert XDH are available only on units with the optional condensate detection feature. The low voltage connections are on the left side of the cabinet, in the rear, near the power connections (see Figure 24). These dry contacts can to be connected to a monitoring unit, such as Liebert’s SiteScan®. For location of the entry points for the condensate detection wiring, see

Figure 25

For units equipped with condensate detection, make low voltage connections according to site-specific drawings.

The Liebert Liqui-tect™condensate detection unit is available only as a factory-installed option.
