9.0 OPERATION
The Liebert XDV’s fan controls are on the front of the unit, near the fans, for easy access. Each switch
controls the operation of one fan (see Figure 36). The separate switches permit the use of only one
fan at a time, reducing the airflow if the Liebert XDV’s full cooling capacity is not needed.
The Liebert XDV’s primary and secondary circuit breakers are also on the front of the unit. They are
at the top left when facing the Liebert XDV (see Figure 36).

9.1 Start the Liebert XDV
The Liebert XDV fans must be on before starting the Liebert XDP or Liebert XDC that will supply
coolant to the Liebert XDVs.
To start the Liebert XDV, press either of the rocker switches to turn on one or both of the Liebert
XDV’s fans.
NOTE
One of the Liebert XDV’s fans must be turned on before either the Liebert XDP or Liebert XDC
is switched on.
One of the Liebert XDV’s fans must be operating at all times that the Liebert XDP or Liebert
XDC is operating. Operating either the Liebert XDP or the Liebert XDC without at least one of
the Liebert XDV’s fans rotating may cause a system malfunction.
