Operation
9.0OPERATION
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).
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.
