If the rack is places horizontal the cooling is better. Temperature: horizontal mounting position: vertical mounting position: 0°C to 60°C 0°C to 40°C Regards, Marcjan

sunn7 Posts: 152 Rating: (2)	Hello Marcjan For example 6es7326-2bf41-0ab0, i found current ouptuts are different for each installtion horizontal 40 Deg C Max- 7.5 A, 60 Deg C Max -5A -- why two limits? Vertical 40 Deg C- 5A so the ouput current depends upon how it is installed and temp inside of cabinet?? Am I corrcect? Thanks sunn7

It's all about exchanging the heat, and that works better when mounted horizontal and lower temperature in the cabinet. Regards, Marcjan
