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
thermocouples placed on the hottest part of the component (out of any direct air flow). See longform datasheet for further information of service life.
