Mounting the Liebert XDV
13
5.2 Suspended Mounting Method
The Liebert XDV also may be mounted above the cabinet by suspending it either from overhead com-
ponents or from Unistruts above the cabinets (see Figures 15 and 16). An optional kit available from
Liebert will simplify mounting the Liebert XDV above the computer cabinet.
Each suspended-mounting method requires that the supporting components be strong enough to sup-
port the Liebert XDV’s weight with coolant, 79 lb. (36kg). Each method also requires that the Liebert
XDV’s placement above the computer cabinet meets the criteria in Figure 10.
To ensure efficient cooling, a baffle or similar object must be installed between the suspended Liebert
XDV and the computer cabinet (see Figure 16). The baffle’s purpose is to prevent the Liebert XDV
from drawing in the cooled air that it has just discharged.
