In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the
components listed in the table below must not be exceeded. See drawing on 2nd page of this
datasheet for component locations. The temperature should be monitored using K type thermo-
couples placed on the hottest part of the component (out of any direct air flow). See longform
datasheet for further information of service life.
