Rockwell Automation 1606-XLP15A Power Supply Reference Manual - Manual (Page 22)

All parameters are specified at 5V, 3A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

20.11. Mounting Operations
Mounting orientations other than input terminals on the bottom and output on the top require a reduction in
continuous output power or a limitation in the max. 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).
