Please note that the maximum permissible ambient temperature at
the detector surface should not be exceeded in case of failure of any
connected water cooling.
Please refer to the technical data of the operating manual for infor-
mation on the ambient temperature of the water cooling required
so protect the electronics from damage by overheating.
The max. ambient temperature decreases when the detector is not
mounted freestanding; the maximum surface temperature must not
be exceeded.
