4.5.2 Uninterruptible Power Supply—Optional
If your XDF is equipped with a UPS, it will require connection to a dedicated electrical circuit. Review
the UPS’s user manual before connecting utility power to the unit.
4.5.3 MP Advanced Power Strips—Optional
MP Advanced Power Strips are available in several power ranges. Consult Table 14 in 12.0 - Specifi-
cations or the MP Advanced Power Strip user manual, SL-28015, for your model’s power require-
ments.
4.5.4 Condensate Drain Connection
The XDF cooling process removes humidity from the air inside the cabinet. The moisture is collected
in a pan and must be removed from the cabinet. The condensate may be fed into a gravity drain or
pumped away with an optional, factory-installed condensate pump.
The gravity-fed drain line must be pitched a minimum of 1/8" per foot (11mm per meter).
The standard XDF condensate drain is a 1/2" NPT female pipe connector. A factory-supplied adapter
permits connecting a 3/4" hose, the same size as a standard garden hose. The adapter is shipped with
the cabinet (see Figure 19).
