Rockwell Automation 1606-XLE480FP Power Supply Reference Manual - Manual (Page 24)

All parameters are specified at 48V, 10A, 230Vac, 25°C ambient and after a 5 minutes run-in time, unless noted otherwise.

22.12. Mounting Orientations
Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a
limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy
of the power supply. Therefore, two different derating curves for continuous operation can be found below:
Curve A1 Recommended output current.
Curve A2 Max allowed output current (results in approximately half the lifetime expectancy of A1).
