3.4 Configuring a Liebert XD System
3.4.1 Number of Modules Supported by a Liebert XDP or Liebert XDC
The numerals designating the model size of a Liebert XD module may be used to configure a cooling
system. For example, a Liebert XDO20 has a model size of 20 and a Liebert XDP160 will accommodate
cooling modules with a cumulative model size of 160.
Similarly, the minimum number of modules connected to a Liebert XDP or Liebert XDC may be calculated
using the model size number for the Liebert XDP or Liebert XDC and the modules. See Table 3.1 below.
Cooling Module Type
Liebert XDC Liebert XDP
Max Min Max Min
Liebert XDCF10 16 6 16 5
Liebert XDH20 8 4 8 3
Liebert XDH32 5 2 5 2
Liebert XDO16 10 4 10 3
Liebert XDO20 8 4 8 3
Liebert XDR20 8 4 8 3
Liebert XDV8 20 8 20 6
Liebert XDV10 16 7 16 5
Table 3.1 Maximum and minimum modules supported by a Liebert XDP or Liebert XDC
Different types of Liebert XD cooling modules may be connected to the same Liebert XDP or Liebert XDC
as long as the sum of their cooling capacity does not exceed the supporting Liebert XDP’s or Liebert
XDC’s model size number.
Example
Continuing the example in Selecting Liebert XD Cooling Modules on page 22, the Liebert XD solution in
that example consisted of:
• Three (3) Liebert XDPs and
• 12 Liebert XDV10s
and any of the following:
• 13 Liebert XDH20s
• 12 Liebert XDO20s
• 15 Liebert XDR20s
1. Using the Liebert XDH20 to continue with the example, the Liebert XD systems could be
populated so that the modules were on dedicated Liebert XDPs.
Liebert XD Loop Liebert XDH20 Liebert XDV10 Maximum Loop Load, kW
Liebert XDP 1 7 modules 0 modules 154
Liebert XDP 2 6 modules 0 modules 132
Liebert XDP 3 0 modules 12 module 120
