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 mechanical details 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.
