2.0 OPERATING CONDITIONS
2.1 Proper Application
The XDK is a water-cooled enclosure and is intended for removing heat from electronic equipment
inside the cabinet. The cooling system in the cabinet is thermally independent of the room air. Water
is used to cool equipment installed in the XDK. No additional cooling of the server room is required.
NOTE
Under certain conditions, a small amount of heat, (approximately 0.5kW), can escape into the
room.
!
CAUTION
Risk of improper operation. Can cause equipment damage. For reliable function of the XDK,
cold water must be available in the correct amount, and at the correct temperature and
pressure. Observe water quality specified in VGB-R 455 P. (see 8.0 - Water Purity
Requirements ).
