installation, refer to DPN000781, available from Liebert by calling 1-800-LIEBERT and from

your local Emerson Network Power representative.

• Smart Module—Liebert XDV smart modules allow remote shutdown, fan failure alarms and auto-

matically switching the second fan On and Off. This saves energy by permitting the unit to run

with one fan and switching on a second fan when the temperature requires both fans for cooling.
